I've been using it for over a year and I think it will work very well for more experienced users. The most important feature is the rangefinder reticle, which makes it easy to calculate the distance to the target with the knob—this was the reason for my purchase. Under the reticle in the right eyepiece there is a compass, illuminated by daylight or an LED, and you can adjust the focus individually in both eyepieces. Waterproofing is a big plus, especially in the rain—after all, these are sailing binoculars. It's solid, comfortable, gives the right magnification, and comes with lens covers and a strap. I definitely recommend it.

The Delta Optical binoculars have been designed with water sports enthusiasts in mind. The Sailor 7x50 model features a rubber-armoured build, is fully waterproof and unsinkable.
The Sailor is equipped with a built-in illuminated compass powered by two LR43 batteries, visible within the optical path, as well as an optical rangefinder allowing you to determine distance based on the known height of an object or vice versa. For greater convenience when converting distances, one of the objective lenses is marked with an appropriate calculation scale.
The Delta Optical Sailor 7x50 uses a classic Porro prism system and individual focus adjustment for each eye. Its universal parameters and high-quality optics ensure a sharp, bright image. The high image quality is achieved by BaK-4 glass prisms and anti-reflective coatings on all optical elements, resulting in excellent light transmission and detailed contrast.

My father-in-law sails a lot, he's tested many pieces of equipment and is very satisfied.
-
I've been using it for a few days. It's lightweight, comfortable to use and doesn't slip in your hands. The image is clear and bright. This binocular is worth noting, especially at this price.
-
It's big, but very good. I highly recommend it.
