Need more versatility than the 25/40x100 Long-Range Observation binocular? This is a modified version of the 25/40x100, that incorporates 1.25" non-rotating helical focusers instead of permanently-mounted eyepieces on turrets. A matched pair of 25x (24.43mm) fully multi-coated wide-angle eyepieces are included. And because the helical focusers are a non-proprietary 1.25" design, your favorite 1.25" eyepieces can be used as well. The eyepieces do not rotate when focusing- a feature found only on high-end helical focusers. The rest of the binocular, including the semi-apochromatic triplet objectives, is the same proven design as found in the original 25/40x100mm. And just like the 25/40x100mm, broadband multi-coatings are used throughout, including the massive porro prisms. |
Complete package price includes binocular, 7x50mm finder-scope, removable handle, lightweight nylon form-fitted case, sturdy wooden, and 25x oculars. Because accurate collimation is critical at higher magnifications, every pair of Oberwerk binoculars is collimated to perfection prior to shipping, so you'll always enjoy perfectly merged images even at highest usable magnification.
The tripod can be upgraded to our premium jarrah hardwood tripod. Either wood tripod can also be custom laser-engraved. Want quick and easy height adjustment? Order with the Manfrotto 475B tripod, which has a crank-up elevator. Need easy mobility? Just add the Manfrotto 181B Auto-Dolly.
