The 8x42 TrailSeeker ED binocular provides high-level outdoor
performance-a perfect choice for avid birders, hunters, and outdoor
enthusiasts. TrailSeeker ED is packed with optical, mechanical, and
ergonomic features that make it comparable to binoculars costing two to
five times as much.

ED Objective Lenses

Extra-Low Dispersion (ED) glass virtually eliminates chromatic
aberration, also known as color fringing, a visual defect common in
binoculars. TrailSeeker ED delivers edge-to-edge sharpness with
excellent color correction and razor-sharp images.

Not all ED glass is created equal. Celestron's high quality ED glass
delivers visibly brighter, sharper images compared to non-ED binoculars.
The difference is especially apparent in low light conditions, such as
at dawn or dusk.

Coatings and Prisms

TrailSeeker ED features fully multi-coated optics and phase- and
dielectric-coated BaK-4 prisms. A binocular can be considered "fully
multi-coated" when all air-to-glass surfaces are coated with multiple
layers of anti-reflectivity coatings so that the maximum amount of light
passes through the glass to the eye.

The prism inside TrailSeeker ED is made of high quality BaK-4 glass
with both phase and dielectric coatings so that more light is reflected
off the prism and diverted through the eye. Taken together, fully
multi-coatings and BaK-4 prisms maximize light transmission for the
brightest, most detailed images possible.

The Body

TrailSeeker ED is composed of lightweight and durable magnesium
alloy. Its tough, rigid frame is coated with rubber to stand up to hard
use in the field. What's more, the binocular is fully waterproof and
filled with dry nitrogen gas to prevent internal fogging of lenses.
TrailSeeeker ED can stand up to even the toughest outdoor conditions.

Viewing through TrailSeeker ED is comfortable for both eyeglass
wearers and non-eyeglass wearers alike, thanks to the durable twist-up
eyecups. Twist through multiple click stops to find the position that
works best for you.

Perfect for a Variety of Uses

TrailSeeker ED features a close focus of just 6.5 feet, making
it perfect for viewing birds, butterflies, plants, or other nearby
subjects. But this 8x42 binocular also offers the magnification needed
to get great views of distance subjects, plus a wide field of view so
you can easily follow them as they move. No matter how you choose to
observe, this versatile binocular is an excellent all-around performer.

Ways to Observe

TrailSeeker ED includes both a neck strap and a carrying harness so
you can choose the option that's most comfortable for you. It's also
tripod adaptable, so you can mount it on any standard photographic
tripod for extended viewing or digiscoping sessions. (Tripod adapter
sold separately.) The binocular also includes a protective soft case for
storage or transport.
