I've had it for over a year and it's great for those more experienced. First of all, it has a rangefinder reticle which makes it easy to calculate the distance to the target thanks to the dial on the binoculars, that's why I bought it. Under the reticle in the right eyepiece there is also a compass illuminated by daylight from above or by an LED, which is why the focus is set separately in the right and left eyepieces. Waterproofing is a plus, which often proves itself in the rain; after all, it is a sailing binocular. It is solid, handy, the magnification is sufficient, it comes with front and rear caps, and also a strap. I recommend it.

Delta Optical binoculars designed for water enthusiasts. The Sailor 7x50 is rubber-armoured, fully waterproof, and also unsinkable.
The Sailor model features a built-in illuminated compass, powered by two LR43 batteries, visible in the binoculars’ optical path, as well as an optical rangefinder that allows you to calculate distance based on the known height of an object and vice versa. For easier calculation, an appropriate scale is placed on one of the objective lenses.
The Delta Optical Sailor 7x50 is based on a classic Porro prism design with an easy-to-use, individual focus adjustment for each eye. The binoculars’ practical features are complemented by versatile specifications and excellent optical performance. Bright and clear images are ensured by high-quality BaK-4 glass prisms and anti-reflective coatings on all optical elements. This guarantees high light transmission and high-contrast images.

My father-in-law sails quite a lot, has tested many already and praises this one.

I've been using it for a few days. It is lightweight, handy, and doesn't slip from your hands. The image is bright and sharp. A binocular worth recommending for a good price.
