Built to U.S. military specifications for optical performance, waterproofness and durability, these are among the very best marine binoculars made. Lenses and prisms are made with Fujinon's exclusive rare-earth glass formulations featuring a proprietary zirconium oxide Electron Beam Coating (EBC) process that enables them to transmit an incredible 95% of the light striking the objective lenses, a critical advantage in low light, such as at dawn and dusk.
The rubber-armored housings are a lightweight, aluminum alloy not plastic. "Flat field" lenses eliminate all visible distortion and astigmatism from the center to the edges for excellent edge-to-edge sharpness. 23mm eye relief provides a complete image even if you wear glasses. The compass model features a large, stable and accurate compass and reticle. Nitrogen-filled, 100% waterproof. A comfortable padded neckstrap is included.

Comments about Polaris 7x50 Binoculars:
My husband and I have sailed for the past twenty years. We have owned the same pair of Fujinon Polaris binoculars for close to that entire time. We still use them and are now adding a second pair. This is an excellent investment and a great product.
