The Minox BN 7x 50mm represents the reference class for the basic models within the Natick Line. Equipped with Porto prisms, these binoculars offer a very high light transmission combined with an extremely high plasticity for a spatial image. Position and distance to viewed objects can be precisely determined. On top of that, the compact and ergonomic construction offers a secure hold, preferred by maritime and water sports enthusiasts. The Minox BN 7x50 has a non-slip robust housing and is water tight down to a depth of 5 meters (16.4 feet). The nitrogen filling protects the inner optical elements from corrosion and fogging.
