Steiner 7x50 Observer w/Compass Binoculars

Built to use; built to last!

The Steiner 7x50 Observer binoculars with compass are an indispensible tool for the mariner. Offering tough, dependable marine optics, they also incorporate the world's most stable and easiest-to-read compass system.

The new 7x50 Observers offer superb performance at an exceptional price. They're equipped with Steiner's Sports Auto-Focus system. That means you set them once for your eyes, and they keep everything in focus from 20 yards out to infinity without being reset. With Observers in hand, you won't miss a wind-swept rock while you're fiddling with a focus knob.

The compass system also includes a range-finding reticle to aid in docking or obstacle-avoidance, and there's electronic compass illumination to help you take bearings in darkness.

Observers are guaranteed waterproof and shockproof to stand up to harsh marine use. In fact, their rubber armoring prevents slipping, even on a wet surface. They operate on two E344 alkaline batteries, too, and they're covered by a 10-year limited warranty.

How to use the distance range reticle

Divide the known height of an object by the points read on the reticle scale as seen through the binocular. Assuming the known height of the landmark is in feet, the result is the range expressed in thousands of feet. Example: A lighthouse is known to be 150 feet high, and appears to be 15 points on the vertical scale of the reticle. 150 ?15 = 10, so the distance to the lighthouse is 10,000 feet.
