The superb Adler 7x50GAL marine binocular is just £129.99 inc UK p&p!

The Adler 7x50GAL is a top specification all round night glass offering superb wide-angle viewing in all lighting conditions. The Bak 4 optics and special IR anti-reflection coatings provide high contrast images that can cut through haze and poor light. The Nautic is fully waterproof and is nitrogen gas purged to prevent fogging in temperature changes.

A further great feature of the Promarine 7x50GAL is the over-sized porro prisms delivering extra field of view (132m @1000m) compared to normal 7x50s.

The 7x50 size is often referred to as a "night glass" as it has great light gathering power and will show the user a much brighter twilight image than most other sizes (the 7x50 size have always been favoured by seamen for this reason).

However, the Adler GAL also has specialist features to make the glasses indispensable to the mariner.

Compass: Integrated compass with fully illuminated bearing display visible in the binocular.

Illuminated reticule: Distance reticule fully illuminated by red light at the touch of a button. A target distance calculator is integrated into the left-hand objective barrel.

The semi-hard case is of padded nylon weave. The Adler 7x50 GAL is supplied with a special wide flotation neck strap to allow the bino to be recovered should it be lost over the side. The extra-wide strap also helps relieve neck strain.

The wide-angle long eye relief eyepieces are equipped with large push down soft rubber eye cups to provide views of maximum FOV to all users including spectacle wearers. The Promarine 7x50 is equipped with tethered splash/rain guards to cover objective lenses and a seperate rain-guard for the eyepieces (see picture detail).
