Alpen Optics Apex XP 10×42 ED Waterproof Binoculars with Long Eye Relief, Bak4, PXA Coating

The Apex XP 10×42 binoculars combine high definition optics with a large 42 mm objective lens to deliver bright, detailed views in changing light conditions. With 10x magnification, ED extra low dispersion glass, and BaK4 roof prisms, the optical system is built to preserve contrast, clarity, and natural color across the viewing field. A 340 feet field of view provides a broad perspective for observing wildlife, scenery, and distant subjects.

Advanced Optical Coatings for Clearer Viewing

Fully multicoated lenses work with PXA phase coating to support sharp resolution and accurate color fidelity. HR metallic prism coating further enhances light transmission and image brightness, helping the binoculars maintain strong visual detail when available light begins to fade. The ED optical system also helps reduce unwanted color dispersion for a cleaner, more defined image.

Waterproof and Fog Resistant Construction

The Apex XP binoculars are waterproof to 1 meter for up to 30 minutes, supporting dependable use during changing outdoor conditions. The interior is purged with nitrogen gas to help prevent internal fogging caused by temperature changes. This sealed design helps keep the optical system clear during field use in damp, cool, or variable environments.

Comfortable Control for Extended Observation

A center focusing system allows straightforward adjustment, while twist up eyecups and 15.2 mm eye relief support comfortable viewing. The binoculars focus as close as 8.2 meters and weigh 2.3 pounds. Their combination of large objective lenses, coated BaK4 optics, and weather resistant construction makes the Apex XP 10×42 a capable choice for detailed outdoor observation in both daylight and lower light conditions.
