Hawke Endurance ED 7x50 Marine Binoculars with Compass

The Hawke Endurance ED Marine Binoculars are 7x50 in blue with a built-in compass, on roof prisms with a 1/4-20 tripod mount.

The compass is the reason to take this over the plain 7x50. It projects a bearing into the field of view, so a landmark can be sighted and its bearing read without lowering the glasses or picking up a second instrument. On a moving deck that matters. Anything that needs two hands and two objects gets done badly or not at all.

Seven power is the marine standard because it is the highest magnification a person can hold steady on a pitching boat. Anything more and the image moves faster than the eye can track. A 50mm objective against 7x gives an exit pupil of just over 7mm, so these stay bright at dawn and dusk when smaller glasses go dark. Explore more outdoor optics and navigation.
