NEW — Really Nice. Read on…..

Developed and used by the US Government, these are 8×40 military grade binoculars.  The NATO Stock Number (NSN) is 6650-01-423-2834.  These are used in the field by DEA, FBI, Border patrol, USAF and other agencies on gunnery ranges, for security, surveillance and at borders for observation.  These feature a natural rubber exterior and superb optics with excellent light transmission, good eye relief, and high color accuracy.

Have you ever caught a glimpse of a brightly colored bird while sitting in your backyard and wished you could see it closer?  You’ll love this pair of full-size Clearvu binoculars from Marathon.  They’re the perfect accompaniment for sporting events, sightseeing, bird watching, wildlife viewing, hunting, astronomy, personal security and so much more.  The Marathon Watch Company supplies these high-quality binoculars to the US military.

Get even more use out of this product by mounting the binoculars on a tripod to view an object for an extended period of time.  Each pair of Marathon Clearvu Binoculars features BMC Coating on lenses and Fully Broad Band Multi-Coated Lenses that provide superior image brightness that allows you to easily see in low light conditions.

I have personally used this same model for birding in the mid-western US and find it to be excellent in all respects.  These are extremely easy to use with glasses and are preferred to my Nikon and Leitz optics of similar focal length.  I’ve also supplied a large number of these to professional birders, ornithologists, geologists and globe travelers…..all have been impressed with the quality especially at this price point.

The binoculars also have a tripod mount for fixed or stationary observation.  The 40mm objective allows for a lot of light to enter thus providing a brighter image in low light. Great for birds, surveillance, marine use or stars!
