Fujinon S 16x40 Binoculars

The Fujinon 16x40 Stabiscope Binoculars deliver perfectly stable views even at extended distances. Using advanced gyroscopic stabilisation, they counteract shake from unsteady hands, moving vehicles, or rough seas, keeping the image steady whether pointed straight ahead, upwards, or downwards. With enhanced 16x magnification and a 167 ft (51 m) minimum focus distance, these binoculars are ideal for long-range observation.

Exceptional Optics

Equipped with phase-coated BAK4 roof prisms and full Fujinon EBC multi-coatings on all optical surfaces, the S1640D provides bright, sharp, high-contrast images. Optional haze eyepiece filters further improve clarity under challenging conditions.

Built to Last

100% waterproof and fogproof, with a rugged rubber-armoured housing, the binoculars withstand harsh marine, aerial, and land-based environments. Interpupillary adjustment of 60–70 mm and ±5 dioptric correction allow comfortable, precise focus for any user. Peel-down eyecups enhance viewing comfort, and the binoculars are designed for left- or right-hand use.

Flexible Power Options

The Fujinon S 16x40 Binoculars can be powered from 12–32 VDC vehicle systems or with four AA batteries or a single 2CR5 battery, providing versatility in the field.
