Building off the success of the 14x40 TSN IS binoculars, the Fujinon 14x40 TSX1440 Techno-Stabi Image-Stabilized Binoculars get an upgrade with a wider stabilization range of ±6°, a buoyant chassis design, and the capability of running on rechargeable NiMH batteries—significant improvements over the regular model.
With these new X version binoculars, you can enjoy the high power of 14x magnification without having to use a tripod. You'll see the details of far-off subjects without the distracting hand shake that typically spoils the view of traditional high-power optics, and you'll find them especially useful when glassing from a moving vehicle or while running a boat across choppy seas.
Fully multi-coated optics and reverse-Porro prisms deliver a bright and crisp image with accurate color and vivid contrast, and the wide exit pupil and twist-up eyecups make the Techno-Stabi comfortable to use while wearing glasses and viewing through them for long periods of time. They will run for up to 18 hours on the four included AA batteries, or 22 hours with your NiMH rechargeables, and come with a case and a strap.
