The Celestron TrailSeeker ED 10x42 is a roof-prism binocular built for birders, hunters and general outdoor use. Its edge-to-edge sharpness comes from extra-low dispersion objective glass, fully multi-coated optics and phase- and dielectric-coated BaK-4 prisms, which together cut color fringing and hold brightness in low light. A 10x magnification and 42mm objectives give a versatile all-round view, and the magnesium body is sealed and nitrogen-purged for weather resistance. It competes with prisms that cost far more, though at this level it is not a true alpha-glass rival.

Owners of the TrailSeeker ED line generally rate the optics highly for the money, praising sharpness and color control, while noting the usual 10x handling trade-offs.
The TrailSeeker ED 10x42mm is a roof prism binocular for outdoor use such as birding and hunting. Its extra-low dispersion (ED) objective lenses reduce chromatic aberration, also called color fringing. The optics are fully multi-coated, and the BaK-4 prisms have phase and dielectric coatings to increase light transmission.
The body is lightweight magnesium alloy covered in rubber. It is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of the lenses. Twist-up eyecups with multiple click stops suit both eyeglass wearers and non-wearers.
Close focus is 8.2 feet, so it can be used on nearby subjects like birds, butterflies and plants. The 10x magnification and wide field of view are meant for distant subjects as well. It can be mounted on a standard photographic tripod with a tripod adapter, which is sold separately, for extended viewing or digiscoping.
