Fujinon Techno Stabi 14×40 Binocular Review

The Fujinon Techno Stabi binoculars in this test are 3rd generation and feature a magnification factor of 14x coupled with 40mm objective lenses.

Black rubber armor coating in combination with a polycarbonate case offers a high degree of impact protection for the lenses and electronics.

Fujinon Techno Stabi 14×40 Binocular

The rear case panel holds pair of adjustable eyepieces, the battery case release, and in the upper right-hand corner the focus knob.

The range of interpupillary distance adjustment of the eyepieces is not as high as some of the other binoculars, however in testing we did not find this to be an issue.

These binoculars were the heaviest tested weighing at 47.5 ounces. Still that is only 7 ounces heavier than the lightest IS binoculars in our test.

Fujinon Image Stabilization

Fujinon uses one of the most sophisticated stabilization system we’ve seen in an image stabilized binocular. It utilizes input from two piezo gyro vibration sensors, one for the vertical axis and one for the horizontal axis, to detect cyclical and repetitive motion. Plus it uses the input from another pair of gyro sensors, again one on the vertical axis and one on the horizontal axis, to detect binocular direction.

These four inputs are sent to a microprocessor that sends output signals to a pair of direct drive motors that instantaneously move the gimbaled erecting prism to correct for any movement. Fujinon, in the owner’s manual, says the system will correct for up to 5 degrees of motion in either direction. Our testers found the Fujinon image stabilization system to be a top performer.


This binocular focus by using the right eyepiece diopter and center focus knob. We found the focus knob a bit hard to turn with one finger.

Rubber eyecups extend back from the ocular lenses and must be folded down to accommodate eyeglass wearers.


Two switches located on the top left-hand side of the case control the stabilization on the Fujinon binoculars. An LED facing the user indicates condition. Power-up the IS system by momentarily press of the power button. A second press activates the system. You’ll know it’s working by the electric-motor sound that emanates momentarily from the case. The LED glows green when the IS system is operating. A momentary press of the power-off button shuts down the system.


The Fujinon Techno Stabi binoculars garnered an excellent viewability rating from our test crew. Their superior stabilization system held the image steady and provided outstanding results by allowing our testers to read several markers that were beyond 1 nautical mile from the test boat.

Odds and Ends

Four AA batteries located in a latched compartment on the bottom side of the binocular case supply power for the electronics. In addition, two different option kits allow the user to power these binoculars from either ships AC or DC power if they desire.

A removable hand strap fits on either side of the case. Our testers preferred to use the Fujinon Techno Stabi binocular with the hand strap removed and neck strap installed.

One real bonus with these binoculars is the fact that Fujinon ships them in a custom fitted Pelican hard case for the ultimate in storage protection.

A wide padded neck strap is also standard.

These binoculars are not equipped with any front lens covers.

These binoculars carry a 1-year warranty.

Final Thoughts

An advanced image stabilization system coupled with good quality optics make the Fujinon Technos an excellent choice for any boater.
