Alpen Apex Steady 20x42 HD Binoculars with Image Stabilization

20x magnification from a handheld binocular is nearly impossible without stabilization. The Alpen Apex Steady 20x42 HD makes it practical with a built-in optical image stabilizer and 2-axis gimbal that turns 20x handheld viewing from theory into reality. The 42mm HD glass objectives with UBX, PXA, and LPE coatings pull in bright, high-contrast images across a 58-meter field of view at 1,000 meters, and the 644-gram body runs on a single AA battery.

Key Features

• Optical image stabilization with 2-axis gimbal — A prism compensator reduces hand shake at 20x magnification. Two stabilization modes: Balance Mode (green LED) for tracking moving targets, and Detail Mode (orange LED) for maximum steadiness on stationary subjects. Binoculars remain fully functional as standard optics if the battery runs out

• 42mm HD glass with triple-coating system — UBX multi-layer coatings maximize light transmission, PXA phase coatings boost contrast, and LPE (Lotus Pearl Effect) hydrophobic coatings repel water and dirt from the lens surfaces

• 58m field of view at 1,000 meters — Focused reach at 20x magnification for picking out detail at long distances. 4-meter close focus distance allows near observation

• BaK-4 roof prism with long eye relief — Full field of view for eyeglass wearers. LE eyepieces with twist-up eyecups and individual diopter adjustment

• IPX4 splash-proof and nitrogen-filled — Withstands rain and wet conditions. Nitrogen fill prevents internal fogging during temperature swings: stepping from a warm vehicle into cold air, or glassing in marine weather

• 644 grams on a single AA battery — The stabilization system runs on one AA battery, and the binoculars still work unstabilized if it runs out. The body measures 185 x 114 x 75mm

Who It's For

Hunters who need to identify game at long range. The optical stabilizer makes this usable from unsupported positions: no tripod, no rest, just steady views across ridgelines and open terrain.

Boaters, sailors, and marine users. The IPX4 rating plus LPE hydrophobic coatings handle spray and wet conditions.

Eyeglass wearers. The long eye relief of the LE eyepieces and the twist-up eyecups deliver the full field without removing glasses.
