The image-stabilized Fujinon 12x40 S1240D Stabiscope Binoculars use gyroscopic stabilization to counteract any movements applied to the binoculars, whether from shaky hands or speeding watercraft. Unlike other stabilizers, the Stabiscope's ±5° of compensation will work with the optics aimed along any axis. A user can aim the Stabiscope straight up or down, at the zenith or nadir, and still enjoy stable viewing, making the Stabiscope the most sensible choice for law enforcement use from a helicopter.
The Stabiscope binoculars are compatible with multiple power sources. They can be powered with 12-32 VDC electrical systems found on most land, sea, and air vehicles, as well as four AA batteries or a single 2CR5 battery.
The Stabiscope binoculars are designed for either left- or right-hand use, and optional accessories include polarizing filters and eyecups.
