Zero Tube 10×25 Monocular
The Zero Tube is an advanced monocular—engineered for backcountry missions, fast movement, and demanding conditions. Featuring ED glass, dielectric-coated BaK4 prisms, and fully multi-coated lenses, it delivers high resolution, contrast, and color accuracy in a form factor that all but disappears in a kit. This is precision optics for people who move light and look far.
Waterproof, fogproof, and built with a rugged, no-slip housing, the Zero Tube performs in the alpine, on the water, and deep in the field. A built-in carry clip keeps it within reach, while its ultra-compact design makes it easy to forget—until needed. When clarity, durability, and packability matter most, the Zero Tube is the one to bring.
- Extra-low dispersion (ED) glass sharpens resolution, improves contrast, and delivers more accurate color—so fine details stay crisp when you’re glassing terrain, wildlife, or distant lines
- Premium BaK4 prisms with dielectric and phase coatings maximize light transmission and clarity, especially in low-light conditions when seeing clearly matters most
- Rugged, impact-absorbing housing feels solid and natural in hand, with added grip to protect the optics when they inevitably take a hit along the way
- Ultra-compact form factor at just 110 × 40 mm makes the Zero Tube a highly packable high-performance monocular in its class—easy to carry, hard to leave behind
- Waterproof (IPX7) means it is built to handle storms, splashes, and full submersion up to 1 meter for 30 minutes
- Fogproof construction with nitrogen-filled chambers prevents internal fogging as temperatures and conditions change
- Twist-up eyecup adjusts easily for a comfortable fit, whether you’re wearing glasses or not
- Integrated carry clip attaches securely to packs or belts for fast, one-handed access when the moment appears
- No-Matter-What™ Lifetime Warranty backs every unit
