The Best Optics for Big Game Hunting: A Comprehensive Guide
A successful big game hunt depends on more than just the right rifle — quality optics are equally essential. Whether you’re glassing distant ridgelines for elk, spotting pronghorns across open prairie, or taking a precise shot at 300 yards, the right scope, binocular, or rangefinder can make all the difference.
This comprehensive guide breaks down the optics every big game hunter should consider — how to choose the right magnification, features, and gear for your terrain and target species.
And when you’re ready to put your setup to the test, explore guided big game hunts across North America through Find A Hunt — your trusted source for vetted outfitters and unforgettable hunting experiences.
Why Optics Matter in Big Game Hunting
Big game animals like elk, mule deer, moose, and sheep live in vast, challenging country. Spotting them requires clarity, light transmission, and stability. Optics not only help locate game but also ensure ethical shot placement by giving you a clear, confident sight picture.
In short:
-
Binoculars locate game.
-
Spotting scopes evaluate trophy quality.
-
Riflescopes ensure precision.
-
Rangefinders confirm exact distances.
Together, these tools transform your effectiveness in the field.
1. Riflescopes: The Hunter’s Precision Tool
A reliable riflescope is your aiming system — critical for accuracy, consistency, and confidence.
Choosing the Right Magnification
-
Short to Mid-Range Hunts (Timber, thick brush): 2–7× or 3–9× scopes offer wide fields of view and quick target acquisition.
-
Open Country and Mountain Hunts: 4–16× or 3–18× models provide the reach for longer shots across canyons or plains.
-
Extreme Long Range: 5–25× scopes are ideal for precision shooters chasing mountain goats, sheep, or pronghorns.
Key Scope Features to Consider
-
Objective Lens (40–50mm): Larger lenses gather more light — useful during dawn and dusk when big game moves most.
-
Tube Diameter: 30mm or 34mm tubes allow greater elevation adjustment and durability.
-
Reticle Style:
-
Duplex or BDC for general hunting.
-
MIL or MOA reticles for long-range dialing and holdovers.
-
Turrets: Look for capped turrets for traditional hunting or exposed tactical-style dials for long-range shooting.
-
Lens Coatings: Fully multi-coated lenses improve clarity and reduce glare.
-
Durability: Waterproof, fog-proof, and shockproof construction is a must for mountain and backcountry hunts.
Expert Tip
Zero your scope at 200 yards for most North American big game hunts — it’s the most practical compromise between close and long-range shots.
2. Binoculars: Your All-Day Glass
Binoculars are your primary scouting and observation tool. A good pair saves countless miles of hiking and helps you identify game from afar.
Recommended Magnifications
Terrain Magnification Objective Size Example Use Dense Forest or Timber 8×42 Wide view for close quarters Whitetail or black bear Open Country 10×42 Balance of field of view and detail Mule deer or elk Mountain & Desert 12×50 or 15×56 Long-range glassing Pronghorn, sheep, or coues deer
Features to Look For
-
ED (Extra-low Dispersion) glass for sharper resolution and color contrast.
-
Waterproof and nitrogen-purged designs for all-weather reliability.
-
Tripod adapter compatibility for steady long sessions.
-
Lightweight frame — fatigue adds up fast during long glassing days.
Top Brands Trusted by Hunters
-
Vortex Optics (Viper HD, Razor HD)
-
Leupold BX-Series
-
Swarovski EL Range
-
Zeiss Conquest HD
Pro Tip: Use a chest harness to carry your binoculars — it keeps them accessible, stable, and protected from brush and dust.
3. Spotting Scopes: Long-Range Clarity
Spotting scopes are vital for evaluating game at long distances or confirming trophy quality. They also double as great range companions for zeroing rifles.
Spotting Scope Essentials
-
Magnification: 20–60× or 25–50× adjustable zoom.
-
Objective Lens: 65mm for packability, 80–85mm for maximum light and resolution.
-
Angled vs. Straight Eyepiece:
-
Angled for comfort during long glassing sessions and sharing with partners.
-
Straight for fast target acquisition.
-
Tripod Stability: A sturdy, lightweight carbon or aluminum tripod is essential for steady images.
Use Case Examples
-
Elk or Mule Deer: Spot from ridge to ridge and identify antler size.
-
Sheep or Goat Hunts: Evaluate full-curl rams or billy goats miles away before committing to a stalk.
4. Rangefinders: Precision at Any Distance
Rangefinders take the guesswork out of shooting. Even experienced hunters misjudge distance in broken terrain — a quality rangefinder ensures you know your hold.
Key Features to Look For
-
Range Capability: At least 1,000 yards; more for open-country hunting.
-
Angle Compensation: Critical for steep mountain shots — adjusts for true horizontal distance.
-
Scan Mode: Continuously updates distance while panning.
-
Readout Speed: Instant readings are invaluable when animals move quickly.
Recommended Options
-
Leica Rangemaster CRF 2800.COM
-
Sig Sauer KILO Series
-
Vortex Ranger 1800
-
Leupold RX-FullDraw or RX-2800
Pro Tip: Practice ranging various landmarks when setting up a stand or glassing position — it saves time when game appears suddenly.
5. Combining Optics: Building the Perfect Setup
Your optical system should complement your hunting style:
Hunting Type Recommended Optics Setup Whitetail in Timber 3–9× scope + 8×42 binoculars Western Elk / Mule Deer 4–16× scope + 10×42 binoculars + 65mm spotting scope Pronghorn / Mountain Hunts 5–25× scope + 12×50 binoculars + 80mm spotting scope Backpack or Wilderness Hunts Lightweight 3–15× scope + compact rangefinder binoculars
Efficiency Rule: Invest in clarity over magnification — a bright, sharp image at 10× is more useful than a dim, blurry one at 20×.
Maintenance and Field Care
Optics are precision tools that deserve protection.
-
Keep lenses clean using a microfiber cloth and lens pen — never wipe dust directly.
-
Store in padded cases during travel.
-
Avoid extreme heat inside vehicles.
-
Always secure tripods and harnesses to prevent drops on rocky terrain.
Pro Tip: Carry a small lens brush or anti-fog wipes — humidity and dust are constant threats on long hunts.
Why Book a Guided Hunt When Testing Optics
Professional guides not only provide access to top-tier game country but also teach field-glassing techniques honed through years of experience. Many outfitters use premium optics — giving you a chance to test brands like Swarovski, Zeiss, or Leupold in real-world conditions.
You can compare vetted guides and book your next big game hunt through Find A Hunt — where expert outfitters help you maximize your gear and your time in the field.
FAQs About Big Game Hunting Optics
Do I need both binoculars and a spotting scope?
If you hunt open terrain or judge trophy animals, yes. Binoculars scan; spotting scopes confirm.
What magnification is best for elk hunting?
A 10×42 binocular and 4–16× riflescope combo covers most elk country.
Should I choose rangefinding binoculars or a separate rangefinder?
Rangefinding binoculars simplify your setup but cost more. Separate units allow two hunters to work together more efficiently.
Are expensive optics worth it?
Yes — superior glass offers brighter, sharper images and better performance in low light, often meaning the difference between spotting or missing game.
What’s the best way to practice with new optics?
Use them before the season — glass wildlife, landmarks, or even road signs at different times of day to understand light performance and magnification limits.
Final Thoughts
Big game hunting is as much about seeing as it is about shooting. The right optics elevate your hunt — helping you find animals faster, judge them accurately, and make confident, ethical shots in any terrain.
Invest in the best glass you can afford, practice using it, and treat it as essential as your rifle. When you’re ready to field-test your gear on your next big adventure, compare outfitters and book your guided hunt through Find A Hunt — where precision optics meet premium hunting experiences.
