7x50 Floating Marine Binoculars: BAK4 Porro prisms and FMC green film anti-reflective coating minimize reflected light and enhance light transmittance, image brightness, and clarity. The 50mm large objective lens and 23mm eyepiece with a high-definition wide view deliver comfortable viewing without eye strain or dizziness. A 6.8mm exit pupil provides ideal image brightness, and the field of view is 396 feet at 1000 yards / 132 meters at 1000 meters.

By utilizing the calculator dial on the left eyepiece, you can directly determine the distance or size of objects. The rangefinder and compass scale are illuminated by a light on/off switch. These low-light vision binoculars offer improved image brightness as long as there is light or in low-light conditions such as lamplight, dawn, and twilight (not total darkness).

Double Focusing System: Two ±5 left and right diopter adjustment rings allow for sharp optical focusing to meet the different requirements based on your individual left and right eyesight. The eye cups can be easily folded down for use with glasses. A non-slip, ergonomic rubber design ensures a secure grip, and heavy-duty rubber armor provides excellent shock resistance. 7x50 Binoculars with Bag and Floating Strap: Easy to carry. Loss-proof objective lens covers attach directly to the binoculars' body to prevent loss and protect lenses and eyepieces. 2 batteries are included.
