About Celestron 10x42 TrailSeeker

The Celestron 10x 42mm TrailSeeker Binocular is a weather-sealed optic designed for close to mid-range observations. This lightweight binocular weighs less than 2 lbs and is compact enough to fit in the side pocket of a daypack. In addition to the TrailSeeker series' streamlined form factor, this fixed-magnification binocular features a phase-correcting dielectric prism coating that renders enhanced clarity and color fidelity. An immersive 65deg. apparent viewing angle and impressive 6.5 ft minimum focus distance complement the fully multicoated lens system and help provide a user-friendly glassing experience that is ideal for birding.

The TrailSeeker binocular has a nitrogen-filled magnesium alloy housing that is built to withstand heavy rain and deliver fogproof performance, making this Celestron optic ready to handle almost any outdoor glassing activity.

Great clarity, good with eyeglasses


from Hillsboro, OR  -  Casual/ Recreational

I am using these for birding and am very happy with my purchase. They are very usable for eyeglass wearers. They are fairly light-weight and are very comfortable to use with the provided back-harness.
