Electronically stabilized marine binoculars are a boon to boaters, allowing for increased magnification versus conventional binoculars because they compensate for shaky hands and rough seas to provide steady viewing.
These are different from the heavy, electrically powered gyroscopic binoculars that use a mechanical gyrostabilizer to create a stable field of vision and carry retail prices as high as $5,500.
Electronic stabilization allows for lighter, more-compact and much-less-expensive binocs. One of the most popular examples is Fujinon’s Techno-Stabi TS-X 1440 binoculars, which feature an electronic gyro-sensor that detects and corrects for any movement. Fujinon claims the world’s highest vibration-correction performance in electronically stabilized binocs.
Fujinon’s steady field of vision facilitates magnification that’s twice as strong as most traditional marine binoculars, which can multiply magnification 7x; anything greater in conventional optics becomes too jittery to be useful in rough seas. But the stability of the TS-X 1440s allows for 14x with a 70-degree field of vision. Powered by four AA batteries and boasting a nonslip finish, the TS-X 1440 binoculars are waterproof and float.

A newcomer has recently entered the market: Koden’s new Sirius 12 features electronic stabilization, an even smaller size and a more affordable price. These lightweight yet rugged binoculars are manufactured in Japan using quality optics and internal components. With a 57.6-degree field of view, the 12x magnification is slightly less than the TS-X 1440 but still stronger than conventional 7×50 nonstabilized binoculars.
The Sirius 12 features a built-in six-axis electronic gyro-sensor to isolate the binocs from the rocking and rolling motion of the boat. The IPX7-waterproof electro-optics feature an easy-to-grip textured surface and an oil-repellent coating to protect the eyepiece and objective lenses. One AA alkaline battery provides 12 hours of operation.
