BARSKA Colorado 10-30x50 Monocular AA13742

Compact monocular for outdoor observation

The BARSKA Colorado AA13742 is a 10-30x50 zoom monocular built for handheld use in the field. Variable magnification from 10x to 30x lets you scan wide or zoom in on distant detail. A 50 mm objective lens gathers light for bright images in changing conditions. Fully coated BK-7 prisms and twist-up eyecups with 14-22 mm eye relief support comfortable viewing with or without glasses.

Suits walkers and event-goers needing one-handed

This monocular fits users who want a single optic for birding, hiking, sports or concerts without carrying a full spotting scope. The centre focus knob operates with one hand and the rubber armour provides a secure grip in wet or cold weather. A built-in tripod socket adds stability for extended watches. Buyers who need wider fields at high power, larger exit pupils for low light, or waterproof and fogproof construction should look at other designs.

10-30x variable magnification range

The zoom spans 10x to 30x, altering field of view from 217 ft to 161 ft at 1000 yds and exit pupil from 2.6 mm to 1.2 mm. Close focus reaches 26.2 ft. This range decides whether the optic matches your typical viewing distance and light conditions. Check those figures against your intended use before buying.
