The  8x42 TrailSeeker Binocular from Celestron 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 colour fidelity. An immersive 65° 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.
