What Western Elk Hunting Demands
Elk hunting out West means glassing open basins, timber edges and far ridgelines at first and last light — often in wind, rain or snow. Most elk are found with binoculars before they're ever seen with the naked eye, so your binoculars do more work than any other piece of gear you carry. They need to stay steady enough to pick out a tan patch at long range, gather enough light at dawn and dusk, and survive weeks of hard use.
10x, 12x or 15x? Choosing Magnification
- 10x42 — the all-round choice. Steady enough to hold by hand all day, bright in low light, and wide enough to scan timber quickly. If you only buy one binocular for hunting, make it a quality 10x42.
- 8x42 — for timber and close country. A wider, steadier view that's easier to use when elk are under 300 yards in thick cover.
- 12x50 — more reach, still handheld. Shows more detail across a canyon, but hand shake is more noticeable. Resting on a pack or tripod helps.
- 15x56 and up — tripod glassing. On a tripod, 15x lets you sit and pick a basin apart, finding bedded elk that a 10x would miss. Handheld, the shake makes them tiring to use.
The western setup many hunters use: a 10x42 on a chest harness for moving and quick looks, plus a 15x56 on a tripod (or a spotting scope) for long glassing sessions. See Magnification vs Field of View for why higher power isn't always better.
Objective Size and Low Light
The second number (42, 50, 56) is the width of the front lenses in millimeters. Bigger lenses gather more light, which matters in the first and last half hour of legal light — when elk move most. Divide it by the magnification to get the exit pupil: a 10x42 gives 4.2 mm, a 12x50 4.2 mm, and a 15x56 about 3.7 mm. Around 4 mm or more stays usefully bright at dawn and dusk. The trade-off is weight: a 56 mm binocular is noticeably heavier to carry up a mountain.
Glass Quality: What You're Paying For
- HD / ED glass reduces color fringing, so the image looks sharper and edges of animals stand out against the background.
- Lens coatings let more light through and cut glare when you glass toward the sun.
- Sealing and fog-proofing (nitrogen or argon purged, O-ring sealed) are essential in rain, snow and big temperature swings.
- Edge sharpness — premium glass like Swarovski's field-flattener designs stays sharp nearly to the edge, which makes long glassing sessions less tiring.

Buying tip: quality used glass often outperforms a new entry-level binocular. See our used optics and read New vs Used Optics first.
Harness and Tripod
A chest harness keeps binoculars protected and ready, spreads the weight, and stops them swinging on a neck strap during long hikes. For 12x and above, a light tripod with a binocular adapter turns hand-shaky glassing into a steady, detailed view — and finds more elk. See Choosing a Tripod and our accessories.
Quick Checklist
- 10x42 for an all-round hunting binocular; 8x42 for thick timber.
- Add a 15x56 or spotting scope on a tripod for big open country.
- Look for HD/ED glass, full waterproofing and fog-proofing.
- Check eye relief if you wear glasses, and try the weight with a harness.
