  • Description

    Our premiere long distance optics, the Eterna angled and straight spotting scopes, impressed critics from the get-go. The inclusion of ED (extra-low dispersion fluorite) glass makes this 20-60X80 scope especially desirable for birders, outdoor enthusiasts, hunters and professionals alike.

    Constructed for optimum performance and extended durability, this waterproof Eterna offers a variety of extra features to make spotting a more enjoyable experience. Our included eyepiece offers eyeglass wearers the luxury of multi-step, long eye relief at 20 to 60 power.

    When mounted on a tripod, the Eterna can be rotated without adjusting the tripod head. A multi-step, locking ring allows the scope to be turned independent of the tripod for comfortable viewing angles.

    Our sight-alignment tube makes locating your subject a quicker process, and a glare-reducing sunshade eliminates reflections on the objective lens.

    Sometimes the little things make all the difference. In this instance, our Eterna's interactive neoprene case fills the ticket. Designed to protect the scope while in use, this flexible slip-on cover offers a sleek alternative to the typical, traditional case.
