20x magnification from a handheld binocular is nearly impossible without stabilization — at that power, the shake from your own pulse makes the image unusable. 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 30 hours on a single AA battery.

Key Features

• Optical image stabilization with 2-axis gimbal — A precision prism compensator neutralizes 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 edge sharpness, 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 extreme distances. 4-meter close focus distance allows near observation without refocusing

• BaK-4 roof prism with 15mm eye relief — Full field of view for eyeglass wearers. LE eyepieces with twist-up eyecups and individual diopter adjustment on the right barrel

• 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 with 30-hour battery life — One AA battery powers the stabilization system for 30 hours. The 185 x 114 x 75mm body balances well for extended glassing sessions

Who It's For

Hunters who need to identify game at extreme range. At 20x, you can pick out antler points, body shape, and movement that lower-magnification binoculars miss entirely. The optical stabilizer makes this usable from unsupported positions — no tripod, no rest, just steady views across ridgelines and open terrain.

Birders and nature watchers who want spotting-scope reach in a binocular form factor. The stabilized 20x optics with a twilight factor of 29 resolve plumage detail and behavior at distances where standard binoculars show only a silhouette.

Boaters, sailors, and marine users who need to read buoy numbers, identify vessels, or spot navigation hazards at distance. The stabilizer compensates for wave motion, and the IPX4 rating plus LPE hydrophobic coatings handle spray and wet conditions.

Eyeglass wearers who have struggled with limited field of view at high magnification. The 15mm eye relief and twist-up eyecups deliver the full field without removing glasses.
