The specialist for water sports

Robust leading-edge optics

For water-sports and professional seafaring, these classic binoculars are still the obvious choice.

Here you find the top features of the Marine binoculars.

The classic 7x50

Tried and tested magnification and a large eye relief, guaranteeing comfortable observation.

Classic Porro design

A short design with a low centre of gravity offers high stability even in a strong swell. Naturally, these binoculars are fully waterproof too.

Bright images

Low light lenses, highly transparent prisms and modern coatings ensure bright, high-contrast images.

7x50 – the classic on the high seas

A 7x magnification ensures an extremely stable image, even on a rolling ocean. The large eye relief of over 7 mm makes for comfortable observation, without losing sight of the target due to a strong swell. A specialist classic with a top notch reputation.

Classic Porro design

The short, robust, classic Porro design gives these binoculars a low centre of gravity for high stability in a strong swell. This means you can set them down securely and pick them up again easily, even with gloves or wet hands.

Impressively bright images

The reason for the bright, clear images lies in the classic optical concept of these standard maritime binoculars. A large eye relief of 7.1 mm, the highly transparent Porro prisms and the modern Carl Zeiss T* coating provide you with bright, high-contrast images, even on the water, where natural contrasts tend to disappear.

Individual eyepiece adjustment

The image sharpness can be adjusted separately for the left and right eyes. Once focussed on the middle distance, you can look further afield without having to refocus. The 7x50 focussing wheel delivers the images you want without lengthy focussing.

Marine 7x50 GA T*

The 7x50 GA T* Marine nautical binoculars are perfect for use at sea. The magnification and eye relief ensure a well-balanced visual experience. Because of their brightness, however, they are also useful for hunting applications.
