DDoptics Binoculars Kaleu 7x50 HDX (63930)

Steiger HDX-C 7×50 marine binoculars with compass (Kaleu) are classic seafaring binoculars designed for reliable navigation and observation on water.

Equipped with an integrated compass and reticle for distance estimation, these binoculars combine high-quality optical coatings with a traditional Porro prism design. The result is exceptionally bright optics, optimized for maritime use. Day and night, they deliver brilliant image clarity, sharpness right to the edges, and a wide field of view of up to 126 m. Thanks to three-step retractable eyecups, spectacle wearers can enjoy the full field of view without restriction.

Ideal marine binoculars with compass and reticle
A large, stabilized marine compass with switchable illumination helps captains maintain their heading even in rough seas. The built-in reticle enables reliable distance estimation, an essential aid for navigation.

Smart Focus – automatic sharpness adjustment
Night navigation often makes focusing difficult. The Steiger HDX-C 7×50 features Smart Focus with internal focusing. After an initial focus adjustment, the eyes automatically adapt to changing distances, eliminating the need for constant refocusing.

Optics with high light transmission
The FMC-HDX coating is optimized for the 400–500 nm wavelength range, corresponding to blue light that is particularly important for human night vision. This results in excellent image brightness and resolution, even as ambient light decreases.

Advanced optical design
High-quality barium crown glass HDX optics ensure that objects remain visible in low light when other binoculars of this class begin to fail. The Porro prism system effectively suppresses flare from moonlight or backlighting. Sharpness extends to the edge of the field, while contrast and color accuracy remain outstanding.

Robust and seaworthy construction
The durable metal housing can withstand drops from up to 1 meter and is waterproof and saltwater-resistant to a depth of 8 meters. Internal fogging is prevented, ensuring clear optics in all conditions.

Recommended as 7×50 marine binoculars
The moderate 7× magnification, wide field of view, and high waterproof rating make the Steiger HDX-C 7×50 ideal for sailing, yachting, and boating, as well as for hiking and outdoor activities. Mariners especially appreciate the bright, reflection-free image with strong contrast during twilight and at night. The integrated compass, manageable weight, and distance-estimation reticle also make these binoculars popular for mountain use and expeditions.
