Compass / Range Finding Binoculars & Monocular

Binoculars and Monoculars are handy tools to have, whether you enjoy bird watching, stargazing, hunting, backpacking, sailing, or any of the other countless forms of recreation in the great outdoors.

The Oceana 8×42 monocular and 7×50 binoculars from Celestron both have some very cool features that make them stand out from the majority of optics on the market. Both of these optics have a built-in magnetic compass, which is seen when looking through the monocular or binoculars. This allows the user to know the compass heading for anything they are looking at through the monocular or binocular that is on the horizon. Aiming above or below the horizon will result in inaccurate compass readings. The compass display is illuminated via a mini skylight on top, and the binoculars having the added feature of a button cell battery-powered light for night operations, which doesn’t do a great job of illuminating the compass, but it gets the job done.

Both the Oceana monocular and binoculars also have the ability to determine the distance to an object or an objects height. This is accomplished with the reticle in the lens and the mil dot markings seen though the lens. The binoculars have a handy calculator ring built around the front of one of the lenses. This makes calculating the range to your target much easier. Unfortunately, the monocular does not have a built-in calculator ring, so doing the math the old fashioned way (L(km)= H (m)/ ) will be necessary.

They both feature Fully Multi-Coated lenses for maximum resolution and high contrast views, a protective rubberized outer coating and are waterproof and fog proof as well. Both also include a neck lanyard and protective lens caps front and back. Unfortunately, on the binoculars the front lens caps have a habit of falling off. Luckily, they have rubber straps that keep them from getting lost. They each also come with a protective nylon case that has belt loops; the binocular case also has a nice padded shoulder strap. Also, these binoculars are focused one eye at a time, so it follows the old fashioned style of binoculars. One advantage the binoculars have over the monocular is their ability to float. I personally tested this by throwing the binoculars into a lake, and as advertised, they indeed floated back to the surface without any leaks or damage.

These optics are well built, rugged, reliable, crystal clear, tack sharp, and worth every penny. If you are on a search for quality optics for adventuring, you need not look further than Celestron.
