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.

Binoculars by Delta Optical for water lovers. This is because the Sailor 7x50 is rubberised, fully waterproof and also buoyant.
It has a built-in illuminated compass, visible in the optical path of the binoculars, and an optical rangefinder, allowing you to calculate the distance based on the known height of an object and vice versa. For easier calculation, a corresponding converter is located on one of the binoculars' lenses.
The Delta Optical Sailor 7x50 is based on the classic Porro design with a convenient individual focusing system for each eye. The extremely practical functionality of these binoculars is complemented by their all-round performance and very good optical properties. A bright and clear image is achieved thanks to high-quality BaK-4 glass prisms and anti-reflection coatings that cover all the binoculars' optical elements. This guarantees high light transmission and high-contrast images.
The set includes:
- Delta Optical Sailor 7x50 C1 binoculars,
- case,
- neck strap
- cloth for cleaning optics,
- manual.

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.
