Hawke Endurance ED 7x42 Marine Monocular in Blue

The Hawke Endurance ED Marine Monocular is 7x42 in blue, on roof prisms with a 1/4-20 tripod mount.

A monocular is half a binocular in every sense: half the weight, half the bulk and one hand free. On a boat that free hand is usually holding something else. It also stows in a jacket pocket, which no 7x50 binocular does, so it is the glass that is actually to hand when something needs identifying quickly.

The trade is depth perception and eye comfort. Two eyes judge distance and can be used for long periods, where one eye tires on extended watching. At 42mm the objective sits between the compact 32 and the full 50, keeping useful low-light performance in a body that still pockets. Explore more outdoor optics and navigation.
