We have created the new Delta Optical binoculars for long-sighted water lovers. It is an irresistible companion during canoeing or boat trip on the lake. Sailor 7x50 is rubber-coated, fully waterproof, and unsinkable. It's only worth keeping her tethered, so that if she falls overboard she does not go too far. However, this is not the end of its advantages. It has a built-in illuminated compass, visible in the optical path of the binoculars and an optical rangefinder, allowing to calculate the distance based on the known height of the object and vice versa. For easier calculation, a suitable calculator was placed on one of the lenses. Delta Optical Sailor 7x50 is based on a classic porro construction with a comfortable, individual focusing system for each eye. The extremely practical functionality of this binoculars complements its universal parameters and very good optical properties. The bright and clear image is obtained thanks to the high-quality BaK-4 glass prisms and antireflection layers that cover all optical elements of the binoculars. It guarantees a high transmission of light and contrasting images that we will enjoy during our cruise.
