The Predator 10x42 is the long-range half of Steiner's hunter-focused pair, adding reach for western and open-country hunting while keeping the CAT game-contrast coatings, bombproof NBR armor, and lifetime warranty that define the line. The sentiment pattern mirrors the 8x42: hunters who own them tend to be loyal - citing decades-long durability and bright legal-light performance - while optics-forum enthusiasts argue Steiner's roof-prism glass is a step behind similarly priced Vortex and Nikon options and reserve their real Steiner affection for the porro-prism Marine classics.
Practically, the 10x42 is light for its class at 23.8 oz, grips beautifully with gloves, and focuses down to 6 ft. The two biggest knocks are specific to this configuration: 14mm of eye relief is simply not enough for most eyeglass wearers, and the 4.2mm exit pupil gives up some of the dusk brightness that makes the 8x42 shine. Add the line-wide gripes - stiff diopter, an eyebox that wants precise eye placement, and marketing claims for the CAT coating that independent testers couldn't reproduce - and this is a binocular you should handle before buying if you wear glasses.
It's best for open-country deer and antelope hunters who want tough, no-babying glass with hunting-tuned contrast and don't wear eyeglasses behind it. On sale around $350-400 it's a defensible alternative to the Vortex Diamondback HD 10x42 (better armor, comparable glass) and undercuts the Viper HD; at full retail, most forum threads steer buyers to the Viper HD 10x42 or up to Steiner's own HX 10x42, which fixes much of what the Predator compromises. Glasses wearers and low-light obsessives should default to the 8x42 version.
Pros
- +The 10x reach suits the open-country side of the Predator's hunting mission - antelope, mule deer, and cross-canyon glassing where 8x runs out of magnification
- +Same CAT (Color Adjusted Transmission) coatings hunters buy the line for - owners report game colors standing out against foliage and filtered glare off leaves
- +Low-light capability earns repeated praise in hunting reviews - testers found dawn and dusk images stayed impressively bright through legal shooting light
- +Steiner's build toughness is the brand's calling card, with NBR rubber armor and owner reports of Predators lasting decades of field abuse
- +Grippy, hunter-friendly ergonomics with molded thumb rests that reviewers single out - easy to hold steady with gloves on
- +6 ft close focus is excellent for a 10x hunting binocular
- +At 23.8 oz it's light for a rugged 10x42 - lighter than a Vortex Viper HD 10x42 and much lighter than alpha hunting glass
- +Lifetime Heritage Warranty and US-based service, with long-term owners vouching that the company stands behind it
Cons
- −The 14mm eye relief is genuinely tight - eyeglass-wearing hunters struggle to see the full field, a bigger problem on this 10x than on the 17mm 8x42
- −Independent testers couldn't verify the CAT coating's game-highlighting claims, finding no measurable visibility advantage over ordinary competitors
- −Optics-forum enthusiasts are notoriously lukewarm on Steiner roof prisms, calling them overpriced for the optical performance and pointing buyers to Vortex Viper HD instead
- −Comparative testing of the Predator line scored clarity and brightness mid-pack for the price bracket
- −315 ft field of view is average, and combined with the fussy eyebox some owners describe, finding and holding the image takes more care than with easier-viewing rivals
- −The stiff, awkward diopter adjustment complaint applies across the Predator line
- −10x magnification amplifies hand shake, and the light weight actually makes it slightly harder to hold dead-steady than heavier 10x42s
- −Wild street-price swings (roughly $330 to $650) mean you can easily overpay - forum advice is to only buy on sale
