Celestron TrailSeeker 10x42 binoculars

Superb performance and value

Take Celestron's rugged TrailSeeker 10 x 42 binoculars with on your next outdoor adventure. Their waterproof and fogproof magnesium alloy housing is ready to handle whatever comes your way. The included binocular harness strap helps takes the weight off your neck for comfortable, all day use. These powerful binoculars provide a crisp, clear view of distant vistas, but have an impressive minimum focus distance of only 6.5 feet so you can get a spectacular, close-up view of Mr. Cardinal on your back-deck bird feeder, too.

The TrailSeeker's fully multi-coated lenses and phase- and dielectric-coated BaK-4 prisms minimize light loss for greater brightness and contrast. Eyeglass wearers can better appreciate the view, too, thanks to twist-up, multi-stop rubber eye cups. Their non-slip, rubberized exterior makes them easy to grip. Celestron's durable, high-quality construction is even backed by a lifetime warranty to ensure long-lasting performance.

    Product Research


    Overview: The Trailseeker Series 10x42 binocular by Celestron is designed for many outdoor activities, including hunting, bird watching, or wildlife and nature viewing. It comes with a neck strap, rainguard, objective lens caps, an innovative binocular harness system, and a padded carrying case.

    Binocular Harness Strap: The Trailseeker 10x42 binocular includes a unique binocular harness system, which is worn like a vest. The harness takes the strain off of your neck and distributes the weight load to your shoulders and torso. The harness is comfortable and keeps the binoculars handy when carrying them during extended use. In addition to the harness, the 10x42 includes a traditional neck strap.

    BaK-4 Prisms: The 10x42 binocular includes high quality BaK-4 prisms and fully multi-coated optics for great image detail, and brighter images, even in low light. The phase- and dielectric-coated prisms dramatically increase light transmission through the prism system for exceptional image quality and views.

    Waterproof: The 10x42 model has a magnesium alloy body with a rubberized coating which keeps water out. The binocular is nitrogen-purged to prevent internal fogging.

    Central Focusing Knob: This Trailseeker Series 10x42 binocular has a large central focusing knob. In addition, the right eyepiece has a diopter for focusing the binocular to your eyesight.

    Twist-up Eyecups: The twist-up eyecups can accommodate eyeglass and non-eyeglass wearers. For non-eyeglass wearers, the eyecups can be twisted to the full "up" position, or twisted to the "down" position for use by eyeglass wearers. There is a middle position which may be more comfortable for some users.

    Tripod Adaptable: The 10x42 binocular has built-in threads that allows the unit to be mounted to a tripod, using an optional tripod adapter.
