DeltaOptical Sailor 7x50 C1 Marine Binoculars with Compass

The DeltaOptical Sailor 7x50 C1 are marine binoculars designed for use at sea - for yacht owners, boat captains, and anyone who loves life on the water. Every detail of their construction serves one purpose: to work reliably in the most demanding conditions afloat. The binoculars are nitrogen-filled and fully waterproof, so rain and waves are no obstacle. The bright-coloured body makes them easy to spot on deck - and in the water too, because the Sailor 7x50 C1 floats. Dropping them overboard does not have to mean losing them.

Illuminated compass and rangefinder - always within sight

The key feature of these marine binoculars with compass is the built-in illuminated compass. Its readings appear directly in your field of view, so you never need to look away from the horizon. Equally useful is the rangefinder scale, combined with a mechanical calculator on the left objective barrel. Together they let you estimate the distance to any object of known height - even in poor light. Every sailor who needs to read a situation quickly and accurately will appreciate both tools.

Optics built for low light on the water

The DeltaOptical Sailor 7x50 C1 uses premium BaK-4 prisms in a Porro arrangement. This combination delivers high image contrast and excellent brightness at dusk or under overcast skies. The FMC (Fully Multi-Coated) anti-reflection coating suppresses unwanted reflections and reproduces colours naturally. The large 7.1 mm exit pupil and a 7.5-degree field of view (132 m/1,000 m) make it easy to follow a moving horizon from a rolling deck. The minimum focus distance of 5 m is practical even in a harbour or a narrow channel.

Individual focus - set once, always ready

Instead of a central focus wheel, the Sailor 7x50 C1 uses separate individual focusing for each barrel. This is the standard approach for professional marine binoculars - once you have set them to your eyes, there is nothing more to adjust. They are always ready to use immediately. The package includes a black nylon case, a tripod adapter, and rubber-rimmed objective caps that stay attached even when you are working with gloves or in bad weather. At 810 g, the weight is reasonable for binoculars with this level of equipment.
