How Do You Choose A Rangefinder For Hunting?

Question

Accepted Answer

Optical Specifications Magnification And Objective Lens Magnification is the first number (6x, 7x, 8x) in specifications. Higher magnification makes targets appear closer but narrows field of view. For hunting, 6-7x magnification provides good compromise between target detail and situational awareness.
Objective lens size (the second number in specifications) affects light gathering and size. A 30mm lens is common and provides adequate light gathering. Larger lenses (40-50mm) gather more light but increase weight and size.
A 6x30 or 7x42 rangefinder is ideal for hunting: good magnification, adequate light gathering, and reasonable size/weight.
Rangefinding Technology Laser rangefinding is the only practical technology for hunting. The rangefinder emits a laser pulse that reflects off the target and returns. By measuring the time of return, the rangefinder calculates distance.
Quality determines accuracy. Budget rangefinders ($50-150) are often inaccurate, reading 5-15 yards off at extended range. Quality rangefinders ($300+) are typically accurate within 1-2 yards.
Distance Capabilities Maximum Range Specifications Maximum range is the farthest distance the rangefinder can measure. Many budget rangefinders claim 1,000+ yard range, but accuracy at these distances is often poor.
Practical maximum range is more important than marketing maximum range. A rangefinder that accurately measures to 600 yards is more useful than one claiming 1,000 yards with unreliable accuracy.
For hunting, 400+ yard accurate range is adequate for rifle hunting. For bow hunting, 300+ yards is sufficient (you won’t attempt bow shots beyond 60-70 yards, but you might range distant animals to judge whether approaching is feasible).
Measurement Accuracy At Range Quality rangefinders maintain accuracy across their entire range. Budget rangefinders often become unreliable beyond 300 yards.
When comparing rangefinders, check specifications for accuracy claims. Most quality rangefinders specify plus-or-minus 1 yard accuracy. Budget models often don’t publish accuracy specifications, which is a red flag.
Specialized Features Angle Compensation (Horizontal Distance) Angle compensation calculates true horizontal distance when shooting at uphill or downhill angles. For rifle hunting in mountain terrain, this feature is valuable.
Without angle compensation, you might rangefind a target at 400 yards at a steep uphill angle, but the horizontal distance (relevant for bullet travel) might be only 350 yards. This 50-yard error significantly affects bullet drop calculations.
Rangefinders with angle compensation display the adjusted horizontal distance. This is more useful than the straight-line distance for rifle shooting at steep angles.
Speed And Measurement Reliability Some rangefinders measure quickly (under 1 second). Others are slower. For hunting, speed matters; you may only have seconds to range an animal before it moves.
Measurement reliability: Some rangefinders have difficulty locking onto certain targets (like distant animals in dark fur against vegetation). Quality rangefinders lock on more reliably.
Ballistic Information Some rangefinders include ballistic calculators, suggesting holdover or turret adjustment based on your rifle setup. This is convenient but accurate only if you’ve input correct data (draw weight, ammunition characteristics, etc.).
For most hunters, external ballistic calculators or scopes with built-in ballistics are more reliable than rangefinder ballistics.
Application-Specific Selection Rifle Hunting For rifle hunting in varied terrain, a quality rangefinder with angle compensation ($400-800) is highly valuable. The ability to accurately range targets at varied angles makes it worth the investment.
Magnification of 6-7x is adequate; higher magnification isn’t necessary since you’ll use a rifle scope for final targeting.
Bow Hunting For bow hunting, a quality rangefinder ($300-500) with 300-400 yard range is adequate. Most bow shots occur at 30-40 yards maximum, so extreme range isn’t critical.
A lighter, more compact rangefinder is preferable for hunting from tree stands where minimizing gear weight matters.
Long-Range Hunting For long-range rifle hunting (400+ yard shots), invest in a quality rangefinder with reliable extended-range accuracy. This is where the accuracy advantage of premium rangefinders justifies cost.
Brand And Quality Considerations Reputable Manufacturers Leica, Swarovski, and Zeiss produce excellent rangefinders trusted by professional hunters. These brands consistently deliver accurate, reliable products.
Vortex Optics and Bushnell offer mid-range options ($200-400) with respectable performance.
Budget brands (no-name options on Amazon, etc.) are often unreliable. You get what you pay for; a cheap rangefinder that’s inaccurate is worse than no rangefinder.
Warranty And Support Quality rangefinders come with manufacturer warranties (typically 5-10 years). This commitment to the product indicates confidence in reliability.
Reputable brands offer customer support if issues arise. Budget brands often disappear or offer no support.
Budget-Conscious Purchasing Cost-Benefit Analysis A quality rangefinder ($400-600) is a multi-year investment, used annually for a decade or more. Annual cost amortizes to $40-60, reasonable for reliable distance information that affects hunting success.
Buying a cheap rangefinder ($100-150) that’s inaccurate is false economy; you’ll be frustrated with unreliable distance information every hunt.
Sales And Discounts Quality rangefinders go on sale periodically. Buying at discount times can reduce cost. Many online retailers offer sales during hunting season.
Used rangefinders from reputable brands can offer value; quality instruments hold their value and function reliably used.
Practical Usage Tips Ranging Multiple Targets When multiple animals are present, range the closest one to determine how far that animal is, then observe other animals relative to the closest. “That bull is 40 yards further than the cow” is useful field information.
Accounting For Vegetation Rangefinders sometimes have difficulty measuring through vegetation. If vegetation is between you and the target, try angling to the side or above the vegetation to get a clear line-of-sight to the animal.
Maintaining Accuracy Through Hunting Season Rangefinders are precision optics. Protect from drops and impacts. Store in a protective case. Avoid exposing to extreme heat, which can affect laser accuracy.
Clean optics carefully with lens cloth and appropriate cleaning solution.
