How to Choose Binoculars for Hunting

Choosing hunting binoculars comes down to one question: can you hold them steady, see through them clearly when the light is bad, and carry them all day without resenting them? Everything else — brand prestige, spec-sheet numbers, marketing language about "HD glass" — is secondary.

The short version: most hunters are best served by a quality 8×42 or 10×42 roof-prism binocular with full multi-coating, phase-corrected prisms, nitrogen or argon purging, and a chest harness. Bigger magnification is not automatically better. Bigger objectives are not automatically brighter in the way people assume. And a $400 binocular with excellent coatings will out-glass a $150 binocular with a larger objective almost every time.

This guide walks through every specification that actually changes what you see in the field, how to test glass before you buy, what to spend at each tier, and how to match a binocular to the way you personally hunt.

Quick Answer: The 60-Second Recommendation

If you take away nothing else: buy the best glass you can afford in an 8×42 or 10×42, and buy a harness with it. That combination solves 90% of hunters' needs.

Reading the Numbers: What "10×42" Actually Means

Every binocular is labelled with two numbers.

• The first number is magnification. A 10× binocular makes an object appear ten times closer than it does to the naked eye. A deer at 400 yards looks like a deer at 40 yards.
• The second number is objective lens diameter in millimetres. A 42 mm objective is the front lens the light enters through.

So a 10×42 is a ten-power binocular with 42 mm front lenses. A 8×32 is an eight-power binocular with 32 mm front lenses.

That is the entire code — but the two numbers interact in ways that matter enormously, and that interaction is where most buying mistakes happen.

The trade-off triangle

Magnification, field of view, and brightness pull against each other:

• More magnification = narrower field of view, more visible hand shake, dimmer image (at the same objective size), and a shallower depth of field so you refocus more often.
• Bigger objectives = brighter image and larger exit pupil, but more weight, more bulk, and a higher price for equivalent optical quality.
• Smaller, lighter binoculars = easier to carry and faster to raise, but less light-gathering when the animal finally steps out at 6:05 p.m.

There is no configuration that wins all three. Choosing hunting binoculars is choosing which compromise you can live with.

Magnification: Why 8× Beats 10× More Often Than Hunters Admit

Magnification is the number buyers fixate on and the one most likely to be over-bought.

The steadiness problem

Magnification multiplies the image — and it multiplies your heartbeat, your breathing, and your shivering right along with it. At 8×, a normal adult can hold a reasonably still image standing unsupported. At 10×, most people can too, but the image visibly "breathes." At 12× and above, handheld glassing becomes genuinely fatiguing: you spend more mental effort stabilising the picture than analysing what is in it.

In practice, the resolution advantage of 10× over 8× is often cancelled out by tremor. A common mistake is buying 12× or 15× binoculars for handheld use because "more power finds more animals," then discovering you cannot detect a bedded deer's ear flick through a jittering image. If you are going above 10×, plan on a tripod from day one — not as an upgrade you'll get around to.

The field-of-view problem

At the same optical design level, going from 8× to 10× typically costs you roughly 15–20% of your field of view. In timber, that difference is the gap between catching a flicker of movement at the edge of the frame and missing it entirely.

When 10× (or more) genuinely earns its keep

• Glassing open sagebrush, alpine basins, or crop fields where animals are routinely 600+ yards out
• Judging antler mass, tine length, or horn curl before committing to a two-hour stalk
• Any situation where you can brace against a pack, a rock, a truck window, or an adjustable shooting stick — bracing recovers most of the shake penalty instantly

Field-tested rule: if more than half your glassing happens inside 200 yards or under a canopy, buy 8×. If more than half happens beyond 400 yards in the open, buy 10×.

Objective Lens Size: Light Gathering vs. Carry Weight

The objective lens determines how much light enters the system. Bigger front lenses collect more photons, which is why 50 mm and 56 mm binoculars dominate serious low-light glassing.

But raw diameter is a blunt instrument. A 42 mm binocular with fully multi-coated lenses, phase-corrected roof prisms, and dielectric mirror coatings will deliver a brighter, higher-contrast image at dusk than a 50 mm binocular with basic coatings. Coatings and prism quality beat diameter at every price point up to roughly $800. If you want the deeper explanation of that relationship, our breakdown of whether larger front lenses help covers the optics in detail.

Practical size classes

A 32 mm binocular is not "bad in low light" — modern 32s with premium coatings are startlingly good. It is simply less forgiving, because the smaller exit pupil demands more precise eye alignment exactly when you are cold, tired, and rushing.

Exit Pupil and Twilight Performance

Exit pupil = objective diameter ÷ magnification.

• 8×42 → 5.25 mm
• 10×42 → 4.2 mm
• 10×50 → 5.0 mm
• 8×32 → 4.0 mm
• 15×56 → 3.7 mm

This is the diameter of the light cone leaving the eyepiece. Hold a binocular at arm's length and you can see it as a bright circle floating in the eyepiece.

Why it matters at dawn and dusk

A healthy human pupil dilates from about 2–3 mm in bright daylight to roughly 5–7 mm in near-darkness, and that maximum shrinks with age — a hunter in their fifties may only reach 4.5–5 mm. When the binocular's exit pupil is larger than your dilated pupil, your eye becomes the limiting factor and the extra light is wasted. When it is smaller, the binocular is the limiting factor and the image looks dim.

That is why an 8×42 (5.25 mm) feels noticeably brighter than a 10×42 (4.2 mm) in the final ten minutes of shooting light, even though both have identical front lenses.

The forgiveness factor nobody mentions

A large exit pupil is also more tolerant of imperfect eye placement. With a 5.25 mm exit pupil you can raise the binoculars slightly off-centre and still get a full image. With a 3.7 mm exit pupil, the same sloppiness produces black crescents on the edge of the view. When a bull steps out and you are snatching the binoculars up one-handed, that forgiveness is worth real money.

Because legal shooting hours are typically defined relative to sunrise and sunset, this twilight window is where most opportunities happen — check the current rules for your state and species through your wildlife agency or the U.S. Fish and Wildlife Service, since hunting hours and species regulations are set locally and change season to season.

Field of View: The Spec That Wins Hunts

Field of view (FOV) is usually printed as feet at 1,000 yards (e.g., "341 ft @ 1000 yds") or as an angular degree figure. Multiply degrees by roughly 52.5 to get feet at 1,000 yards.

Typical ranges:

• 8×42: 380–430 ft at 1,000 yards
• 10×42: 310–345 ft
• 12×50: 270–300 ft
• 15×56: 220–240 ft

Why wide matters more than hunters expect

Hunting rarely involves finding a stationary animal in the open. It involves detecting movement, asymmetry, or a horizontal line in a chaotic background of vertical timber. A wide field lets you sweep terrain in fewer passes, keeps landmarks in frame so you don't lose your place, and dramatically speeds up reacquiring an animal that moves.

A separate spec, apparent field of view, describes how immersive the image feels. Anything above about 60° apparent FOV is considered "wide-angle" and produces that pleasant sense of looking through a window rather than a tube. Wide-angle eyepieces are harder to build without edge distortion, which is one legitimate reason premium binoculars cost more.

Glass, Coatings, and Prisms: Where Your Money Actually Goes

Two binoculars can share identical 10×42 specs and differ by $1,500. The difference lives in components that never appear in the model name.

Coatings — read the exact wording

Manufacturers use precise, legally meaningful terms:

• Coated — a single anti-reflective layer on at least one surface. Entry-level.
• Fully coated — a single layer on all air-to-glass surfaces.
• Multi-coated — multiple layers on at least one surface.
• Fully multi-coated — multiple layers on every air-to-glass surface. This is the minimum you should accept for hunting.

Each uncoated glass-air surface reflects away roughly 4–5% of incoming light. A binocular has 10–16 such surfaces. Do the arithmetic and you can see why coatings, not diameter, dominate real-world brightness.

Prism type

• Roof prisms — straight, slim barrels. Modern standard; more compact and easier to weatherproof. Require phase correction coatings and high-reflectivity mirror coatings (dielectric is best, silver is good, aluminium is basic) to reach their potential. If a roof-prism binocular doesn't state "phase corrected," assume it isn't.
• Porro prisms — the classic offset "N" shape. Optically efficient and cheap to make well, with excellent depth perception, but bulkier and harder to seal. Excellent value if you don't mind the shape.

Glass type

ED (extra-low dispersion) glass, sometimes branded HD or fluoride glass, reduces chromatic aberration — the purple/green fringing you see on high-contrast edges like a dark branch against bright sky. On a well-executed binocular, ED glass produces visibly cleaner edges and better contrast in flat light. On a cheap binocular, "ED" is often marketing decoration.

Optical manufacturers publish transmission curves and coating data for their lines; comparing published specs on official sites such as Zeiss is a far more reliable exercise than comparing retailer bullet points.

What each price tier realistically buys

Waterproofing, Fogproofing, and Build Quality

Hunting optics live in rain, snow, sleet, dust, sweat, and vehicle heat cycles. Sealing is not a luxury feature.

The two separate protections

1. Waterproofing — O-ring seals prevent water intrusion. Quality hunting binoculars are typically rated to survive submersion at a stated depth and duration (commonly 1–5 metres for several minutes). Check the manufacturer's actual claim rather than the word "waterproof" on a box.
2. Fogproofing — the internal air is purged and replaced with dry nitrogen or argon. This eliminates internal condensation when you step from a 20°F morning into a heated truck cab. Argon molecules are larger and leak more slowly over the years, which is why premium optics tend to use it.

Sealing only protects the interior. External lens fogging still happens, and the fix is airflow and patience, not wiping.

Mechanical build checklist

• Rubber armour — sound-deadening and grippy, especially with cold or gloved hands
• Focus wheel — smooth throughout its travel, no gritty spots, no backlash when you reverse direction. Should be reachable and turnable with a gloved index finger
• Twist-up eyecups — must click firmly into detents and stay there. Eyecups that creep down under pressure are a chronic annoyance
• Hinge tension — firm enough that your interpupillary setting doesn't shift when the binocular knocks against your chest
• Tripod adapter socket — a threaded port under the front hinge cover. Even if you don't own a tripod now, don't buy a binocular without it
• Warranty — several major optics brands offer unconditional, transferable lifetime warranties. Over a 20-year ownership window this is a genuine financial factor, not marketing fluff

Fit, Eye Relief, and Eyeglass Compatibility

The best glass in the world is useless if it doesn't fit your face.

Eye relief

Eye relief is the distance behind the eyepiece where you see the full field of view. Eyeglass wearers need 15 mm minimum, and 16–18 mm is meaningfully more comfortable. Below that, you will see a tunnelled, cropped image with your glasses on.

If you wear glasses: twist the eyecups fully down, press the binocular gently against your lenses, and confirm you can see the full circular field with no black edges. If you don't wear glasses, twist the eyecups fully up so your eye sits at the correct distance.

Interpupillary distance (IPD)

Adjust the central hinge until the two circles merge into one perfect circle — not a figure-eight, not an oval. Adult IPD ranges roughly 58–72 mm. Hunters with narrow-set eyes should check the binocular's minimum IPD spec, because some large 50 mm and 56 mm models won't close far enough to fit smaller faces.

Setting the diopter — do this once, properly

Nearly every hunter skips this, and nearly every hunter is glassing with a slightly blurred eye as a result.

1. Set your IPD and eyecups first.
2. Find a detailed object 30–50 yards away — bark texture, a fence post, a sign.
3. Cover the objective lens on the diopter side (usually the right) with your hand or a lens cap. Never close one eye; that changes your eye's focus.
4. Focus the centre wheel until the image in your open eye is razor sharp.
5. Now cover the other objective and, without touching the centre wheel, adjust the diopter ring until that eye is razor sharp.
6. Uncover both. The image should snap into three-dimensional clarity.
7. Note or lock the diopter position — many binoculars have a scale or a locking collar.

Recheck it once a season. A binocular that "went soft" is usually just a bumped diopter.

Testing Binoculars Before You Buy

Store lighting flatters every optic ever made. Test properly:

1. Go outside, or at minimum to a window. Bright fluorescents hide almost every optical flaw.
2. Look at a high-contrast edge — a dark roofline against grey sky, a bare branch against clouds. Check the boundary for purple or green fringing. Less fringing = better glass control.
3. Check edge sharpness. Centre a detailed object, then slide it to the edge of the field. Some softening is normal; mushy, smeared edges are not.
4. Examine deep shadow. Find the darkest area in view — under a vehicle, inside a treeline — and see how much detail you can pull out. This predicts twilight performance better than any spec.
5. Do the exit pupil check. Hold the binocular at arm's length toward a bright surface. The bright circles should be perfectly round and evenly bright. Squared-off or greyed edges indicate cheap prism glass (BK-7 instead of BaK-4) or undersized prisms.
6. Run the focus wheel end to end several times. Count how many turns from close focus to infinity — around 1.5 turns is a good compromise between speed and precision.
7. Hold them up for a full 60 seconds. Arm fatigue, image shake, and eyecup comfort all reveal themselves in the second half of that minute.
8. Compare two models back to back in the same conditions. Optical memory is terrible; sequential comparison is the only reliable method.

Carry Systems: The Accessory That Changes Everything

A neck strap is the worst way to carry hunting binoculars. It bounces, it swings into your rifle stock, it lets the lenses collect rain, and after six miles it makes your neck ache.

A bino harness — ideally a chest pack with a closing lid — is the single highest-value upgrade a hunter can make. It:

• Transfers weight to your shoulders and torso
• Keeps the binocular still while you walk, hike, or climb
• Protects the lenses from rain, snow, brush, and dust
• Gets the glass to your eyes in about a second, one-handed
• Usually adds a pocket for a rangefinder, wind checker, or tags

If you hunt from an elevated position, a harness is also what keeps your optic from dangling into your bow string or safety line — a consideration worth thinking through alongside staying tethered aloft and the rest of your stand setup.

Add a tripod adapter

For anything 10× and up, a tripod adapter transforms the optic. Mounting a 10×42 on a tripod reveals detail you simply cannot resolve handheld — bedded animals, ear tips, antler tines behind brush. Hunters routinely find animals on a tripod that they missed on three handheld passes over the same hillside.

Matching Binoculars to How You Actually Hunt

Whitetail in timber and from stands

Distances are short, light is marginal at both ends of the day, and detection beats magnification. 8×42 is close to ideal — wide field, big exit pupil, forgiving eye placement when you're rushing. Some stand hunters go 8×32 purely to reduce bulk in a confined space. If deer are your primary quarry, our dedicated write-up on whitetail-specific glassing advice goes further into stand-hunting setups.

Western open-country and mountain hunting

You will spend hours glassing, not minutes. 10×42 handheld plus a tripod, or 12×50 / 15×56 tripod-mounted, is the standard approach. Many mountain hunters run a two-optic system: 10×42 on the chest for walking and quick checks, plus a bigger binocular or spotter in the pack for grid-glassing. That system is exactly what pays off on demanding high-altitude spot-and-stalk hunts where you may glass an entire basin before moving.

Bowhunting

Ranges are short and speed matters. A compact 8×32 in a harness is often perfect — light enough to forget about, wide enough to catch movement, and small enough not to foul a release or a string. Bowhunters weighing broader setup decisions may also want to compare fixed and mechanical head designs while they're refining gear.

Predator, varmint, and turkey hunting

Fast acquisition and a wide view beat reach. 8×32 or 8×42 with fast focus. Turkey hunters especially benefit from low weight, since the binocular hangs on a vest all morning.

Guided or vehicle-based hunts

Weight barely matters. Buy the biggest, brightest binocular you're willing to carry from the truck — 10×50 or 12×50 — and enjoy the extra light.

Binoculars vs. Rangefinders vs. Spotting Scopes

Optics overlap, and buying the wrong tool for a job is expensive.

• Binoculars are for finding and evaluating game. Two-eyed viewing is dramatically less fatiguing than one eye, and gives you depth perception. This is your primary optic and should get the largest share of your optics budget.
• Laser rangefinders measure distance. Increasingly common, and worth owning separately or as a rangefinding binocular — a single unit that glasses and ranges. Rangefinding binoculars cost more and weigh more, but eliminate a device and a strap. They shine on Western hunts where every shot needs a verified distance.
• Spotting scopes deliver 20–60× for judging trophy quality and counting points at extreme range. They are not detection tools; they're evaluation tools. If you're deciding whether you need one, our comparison of spotting optics and astronomical designs explains why a hunting spotter is built differently from a stargazing instrument.
• Riflescopes are for aiming, not searching. Never use a mounted riflescope to scan for game — it points a firearm at whatever you're identifying, which violates fundamental firearm safety. Choose it separately; our guidance on selecting the optic on your rifle covers that decision.

For scouting before the season, glass isn't your only option — remote scouting tools can tell you where to point your binoculars in the first place.

How to Actually Glass: Technique Beats Specs

Great binoculars used badly find fewer animals than average binoculars used well.

Sit down and get supported. Standing handheld glassing is the least productive method there is. Sit, brace elbows on knees, or rest the binocular on a pack. Stability directly converts into detected detail.

Grid the terrain. Divide the hillside into bands and sweep each one slowly, left to right, then drop to the next band with a slight overlap. Move in small increments and pause every few seconds — your eye needs stationary time to resolve fine detail.

Look for parts, not animals. You will almost never see a whole deer. You will see a horizontal back line among vertical trunks, an ear rotating, a patch of tan that's slightly the wrong shade, or the white of a rump. Train yourself to notice shape fragments and colour anomalies.

Glass the same country twice. Animals stand, feed, and shift. A second pass over ground you "already cleared" is one of the highest-percentage moves in hunting.

Work the light. First and last light are when animals move and when contrast is highest. Have the binoculars up before legal light and keep them up until you genuinely cannot see.

Rest your eyes. After 20–30 minutes of continuous glassing, look at something 20 feet away for a minute. Eye fatigue degrades detection sharply, and most hunters never notice it happening.

Care, Cleaning, and Storage

Good optics last decades if you treat them sensibly.

• Never dry-wipe a lens. Grit dragged across coated glass leaves permanent micro-scratches. Blow off loose debris first with a blower bulb or lens pen brush.
• Then use a microfibre cloth with a proper optics cleaning fluid or your own breath, working in gentle circles from the centre outward.
• Skip household glass cleaner, paper towels, shirt tails, and alcohol wipes — all of them attack lens coatings over time.
• Dry before storing. After a wet hunt, wipe the body down and leave the binocular out in a warm, ventilated room overnight. Sealing a damp optic into a closed case invites mould on the coatings.
• Store cool and dry, not in a hot vehicle. Repeated heat cycling stresses seals and adhesives over the years.
• Use lens caps in transit, and keep the objective covers on when the binocular sits in a chest harness in brush.

Our step-by-step routine for keeping the lenses spotless covers the process in more detail — worth reading once before your first cleaning, because most coating damage happens in the first attempt.

Common Mistakes to Avoid

• Buying magnification instead of glass quality. A well-coated 8×42 outperforms a poorly coated 12×50 in almost every real hunting scenario.
• Ignoring eye relief because you don't wear glasses today. Prescriptions change. Long eye relief is more comfortable for everyone.
• Skipping the diopter setup. You will blame the binocular for something your right eye is doing.
• Trusting "ruby-coated" or heavily tinted lenses. Coloured coatings on cheap optics distort colour and reduce transmission. Good coatings look faint green, purple, or blue at an angle — never mirror-red.
• Using a neck strap on a full-size binocular. Buy the harness. It costs a fraction of the optic and improves the experience more than a $300 upgrade would.
• Never testing at dusk. The only conditions that matter are the ones you'll hunt in.
• Forgetting the tripod thread. Discovering there's no adapter socket the day you decide to grid-glass a basin is a painful lesson.

FAQ

Are 8×42 or 10×42 binoculars better for hunting?

Both are excellent; they suit different hunters. 8×42 gives a wider field of view, a larger 5.25 mm exit pupil, a steadier handheld image, and better performance in the last minutes of legal light — the better pick for timber, stands, brush, and anyone whose hands aren't rock-steady. 10×42 offers roughly 25% more reach for judging antlers and picking apart distant slopes, at the cost of a narrower field and more visible shake. If you hunt mostly under 300 yards, choose 8×. Beyond 400 yards in open country, choose 10×.

Is higher magnification always better?

No — and this is the most expensive misconception in optics buying. Above about 10×, handheld hand tremor magnifies faster than useful detail, the field of view narrows to the point where scanning becomes slow, the exit pupil shrinks and the image dims, and depth of field shortens so you refocus constantly. Twelve-power and fifteen-power binoculars are genuinely superior — on a tripod. Handheld, most hunters resolve more real detail through a steady 8× than a shaky 12×.

What does "fully multi-coated" mean, and does it matter?

It means every air-to-glass surface in the optical path has multiple anti-reflective layers. Since each uncoated surface reflects away 4–5% of the light entering it, and a binocular has 10–16 such surfaces, coatings can swing total light transmission from roughly 60% to over 90%. That is a bigger real-world brightness difference than jumping from a 42 mm to a 50 mm objective. Treat "fully multi-coated" as a hard minimum requirement.

Do I need waterproof binoculars for hunting?

Yes, in almost all cases. Rain, snow, river crossings, sweat, and condensation from moving between cold air and a heated vehicle are routine. Look for O-ring sealing plus nitrogen or argon purging — the first keeps water out, the second prevents internal fogging when temperature swings. Non-purged binoculars can fog internally for hours, and there is nothing you can do about it in the field.

Should I buy compact binoculars for hunting?

Compacts (28–32 mm) are a legitimate choice, not a compromise pick, if you understand the trade. A quality 8×32 saves 6–10 ounces and significant bulk — meaningful on backpack hunts, in a turkey vest, or in a cramped blind. The cost is a smaller exit pupil, so the final and first ten minutes of legal light are dimmer and eye placement must be more precise. A good 32 mm beats a mediocre 42 mm. A cheap compact is genuinely frustrating at dawn.

How much should I spend on hunting binoculars?

Spend more than feels comfortable, once. Under $150, you get daylight-only performance. The $250–$450 range delivers the largest quality jump per dollar and produces binoculars many hunters keep for twenty years. Above $800 you're buying edge-to-edge sharpness, colour fidelity, and mechanical refinement that matter most if you glass for several hours a day. A practical guideline: if you glass more than an hour per hunt, buy up a tier. Also plan roughly $50–$120 for a chest harness, because it will improve your experience more than the next $300 of glass.

Are rangefinding binoculars worth it?

For Western and long-range hunting, often yes. Combining glass and laser into one unit removes a device from your chest and a step from your shot sequence — you range while you're already looking at the animal. They cost substantially more, weigh more, and need batteries you must remember to check. For timber whitetail hunting inside 150 yards, a separate rangefinder or none at all is usually the smarter allocation of money.

Can I use my riflescope instead of binoculars?

Never for searching. Scanning with a mounted riflescope means pointing a firearm at everything you're trying to identify, which breaks the most basic rules of muzzle discipline — worth revisiting the core rules of safe handling if that habit has crept in. Beyond safety, one-eyed viewing through a narrow field is far slower and more fatiguing than two-eyed binocular use. Binoculars find and identify; the riflescope only aims.

How do I stop my binoculars fogging up externally in cold weather?

External fog forms when warm, moist air meets cold glass — typically when you exhale over the eyepieces or step out of a heated cab. Prevent it by keeping the binocular outside your jacket so it stays at ambient temperature rather than warming against your body, exhaling downward and away, and letting the optic acclimatise for 10–15 minutes before the hunt. Anti-fog wipes designed for optics help. If the lenses do fog, let airflow clear them; wiping just smears the moisture and risks scratching.

Your Buying Checklist

Before you hand over money, confirm every line:

• Magnification you can hold steady for a full minute — 8× or 10× unless you own a tripod
• Fully multi-coated optics stated explicitly (not just "coated" or "multi-coated")
• Phase-corrected roof prisms, or porro prisms
• Waterproof and nitrogen/argon purged
• 15 mm+ eye relief if you wear glasses (16–18 mm preferred)
• Twist-up eyecups that hold their position firmly
• Smooth focus wheel, reachable with gloves, no gritty spots
• Tripod adapter socket present under the hinge cap
• Round, evenly bright exit pupils when held at arm's length
• Field of view appropriate to your terrain (wide for timber)
• Total weight checked with your loaded pack, not on its own
• Strong, ideally transferable, manufacturer warranty
• A chest harness budgeted alongside the binocular
• Retailer return window long enough to test at last light

Pair that with the rest of a well-considered kit — a solid rest, reliable hearing and eye protection, and the fundamentals covered in our full field kit rundown — and your optics will be the strongest part of your setup rather than the weakest.

Conclusion

The best hunting binocular is not the one with the biggest numbers on the barrel — it's the one you can hold steady, see through clearly at last light, and carry comfortably for ten hours without thinking about it. For the overwhelming majority of hunters, that means an 8×42 or 10×42 with fully multi-coated, phase-corrected optics, nitrogen or argon purging, and at least 15 mm of eye relief, worn in a chest harness. Choose 8× if you hunt timber and close cover; choose 10× if you hunt open country. Then spend whatever remains of your budget on glass quality rather than on extra magnification.

Your next step: take your top two candidates outside within 30 minutes of sunset, set the diopter properly on both, and look into the darkest shadow you can find. Whichever one shows you more detail in that shadow is the one to buy — that single test will tell you more than any spec sheet ever will.
