Delta Optical Sailor 7x50 is a compact waterproof binocular. If you like going on a raft or on a boat while observing the surrounding landscape, or you monitor nearby vessels from your yacht, the Sailor series, i.e. “sailor”, is the ideal choice for you. The binoculars are completely waterproof and the optics are protected against fogging with nitrogen. The body is also fully rubber-armoured so that nothing happens to the binoculars even if they fall into the water. And if they really do slip out of your hands somewhere, you will easily find them in a moment thanks to their yellow-black reflective colour.
It is an ideal tool for every sailor. It features a built-in illuminated compass, which is visible in the optical path of the binoculars, and an optical rangefinder. Thanks to these, you can determine distance based on the known height of an object, and vice versa.
BaK4 prisms combined with lenses coated with magnesium fluoride (MgF2) give the binoculars high image quality. The binoculars offer an ideal balance of compact dimensions, magnification, and image brightness. The dioptre adjustment of +/- 5 dioptres is located directly at the eyepieces. They weigh only 810 g, so you can comfortably take them almost anywhere. Carrying is made much easier thanks to the strap with caps, or the hard case with its own strap.
