Chisos 10x42 LRF ED Binoculars (Preorder)


Description

The Alpen Optics Chisos 10x42 LRF ED Binoculars are a premium all-in-one optic built for hunters, wildlife observers, and serious outdoor enthusiasts who demand precise distance data alongside exceptional image quality. Featuring ED (extra-low dispersion) glass and BaK4 roof prisms with multi-coating, these binoculars deliver strikingly bright, high-contrast views with minimal chromatic aberration - even in challenging low-light conditions. At just 890 g and with a compact footprint, they're engineered to go wherever you go without weighing you down on long days in the field.

The integrated laser rangefinder measures distances up to 2,743 metres (3,000 yards) for large structures and up to 1,097 metres (1,200 yards) for deer-sized targets, with results projected directly into your field of view via a crisp red OLED display. Two measurement modes - LOS (line of sight) and HCD (angle-compensated distance) - give you the flexibility to get accurate readings on any terrain. Twist-up eyecups, 17 mm of eye relief, and a wide central focusing wheel round out a design that's as comfortable as it is capable.


Key Features

  • ED Glass Optics: Extra-low dispersion glass minimizes chromatic aberration for sharp, color-accurate images across the full field of view.

FAQ

What is the difference between LOS mode and HCD mode on the rangefinder?

LOS (Line of Sight) mode gives you the direct, straight-line distance to your target - useful when shooting or observing on flat terrain. HCD (Horizontal Component Distance) mode compensates for the angle of incline or decline, giving you the true horizontal distance. This is especially important for bowhunters or rifle hunters shooting uphill or downhill, where the angle-corrected distance is what matters for accurate shot placement.

How far can the rangefinder actually measure on typical hunting targets like deer?

On deer-sized targets, the integrated laser rangefinder is rated to measure up to 1,097 metres (1,200 yards). For larger reflective targets such as buildings or cliff faces, it can reach out to 2,743 metres (3,000 yards). Real-world performance may vary based on lighting, weather, and target reflectivity.

Are these binoculars suitable for eyeglass wearers?

Yes - the Chisos 10x42 LRF ED are designed with eyeglass wearers in mind. They offer 17 mm of eye relief, which is generous enough for most glasses wearers to see the full field of view comfortably. The twist-up eyecups allow you to quickly adjust the eye relief position to suit your needs.

What battery does the rangefinder use, and how long does it last?

The rangefinder is powered by a single CR2 battery, which is widely available at outdoor, electronics, and camera stores. CR2 batteries are known for reliable performance in the field, including in cold weather conditions common during hunting season.

Are these binoculars waterproof?

Yes. The Chisos 10x42 LRF ED binoculars are rated waterproof to 1 metre for 30 minutes, meaning they can handle rain, splashes, and brief submersion without issue. They are built with a robust aluminium housing and rubber armouring that also provides shock resistance for rugged outdoor use.

Do these ship on a pallet or in a standard box? Is any assembly required?

These binoculars ship in standard packaging and are ready to use right out of the box - no assembly required. Free standard shipping is available on U.S. orders over $70, with delivery to the continental United States.
