Hawke Endurance ED Marine 7x50 Compass Binoculars

Offshore, when the chartplotter blinks out, the navigation aid you can still trust is the one built into the glass in your hands. Closing an unfamiliar harbor at dusk, you sight the headland or a lighthouse, read a built-in illuminated compass and milliradian rangefinding reticle right in the view, and take a bearing while ranging a known-size landmark as a cross-check. It is a GPS-free failsafe for the moment the electronics quit, wrapped around low 7x power you can hold steady while the deck rolls under you.

This is the flagship of Hawke's Endurance ED Marine line: the same genuine ED (extra-low dispersion) marine glass as the standard 7x50, with the internal compass and reticle added on top. That pairing is what the traditional premium marine-compass binoculars charge two to three times as much for. The compass is calibrated for northern latitudes, so treat every bearing and range as a visual cross-check against your onboard navigation, not a replacement for it. What you get for the price is real ED optics and a genuine backup instrument in one sealed, waterproof package.

Key Features

• Illuminated compass + rangefinding reticle — read a bearing and estimate the range to a known-size object without leaving the cockpit; the compass lights up for low-light use (CR1225 battery included). A navigation failsafe, not a precision instrument.
• ED glass, fully multi-coated with phase-corrected roof prisms — extra-low dispersion elements curb the color fringing that is worst in the high-glare, backlit-water conditions marine optics live in.
• A true 7x50 night glass — a large exit pupil keeps the view bright at dawn, dusk, and under the stars, while low 7x power stays steady by hand or on a pitching deck.
• Sealed for the water — nitrogen-purged waterproof and fog-proof, built to shrug off spray and weather.
• Floating strap included — drop them over the side and they stay at the surface.
• Compact roof-prism body — lighter and more packable than the classic porro-prism marine binocular, and it focuses closer for double-duty on land.

Ideal For

• Boaters & sailors — an electronics-independent bearing compass and distance reticle in the same glass you scan the horizon with.
• Stargazers — a classic low-power 7x50 for sweeping the Milky Way, framing the Moon, and picking up bright deep-sky objects.
• Dawn-and-dusk birders, anglers & wildlife watchers — the large exit pupil and long eye relief reward glassing in the half-light when wildlife and fish are most active.
