The Leica 10x42 Geovid HD-B 3000 Rangefinder Binocular combines powerful optical performance with a long-distance 3000-yard laser rangefinder and ballistic computer into a highly portable and easy-to-use optic.
Optically, the Geovid utilizes Leica's Perger-Porro prism optical design that yields the compact form factor of a roof prism with the rich depth of field and interference-free light path of a traditional Porro prism. To further improve image quality, is an internal baffle system to suppress stray light and the HDC fully multi-coated optical system that maximizes light transmission, while improving color fidelity and contrast. Its ultra-wide field of view helps to minimize the appearance of the distracting hand-shake that is often associated with holding powerful optics such as this, while also presenting the user with an immersive observational experience.
The range finding system integrates an inclinometer and ballistics computer with the powerful IR laser to improve first-shot accuracy. Its inclinometer measures the relative angle from the user to the target, then combines that with the linear range, to provide an adjusted distance to enable them to better judge the hold-over/-under. The addition of Leica's Advanced Ballistic Compensation system utilizes one of 12 pre-programmed ballistic curves based on common ammunition loads, combined with the adjusted range and environmental conditions, to further improve hold-over/-under accuracy. Users can also create custom curves on the Leica website and load them onto the Geovid, refining the precision even more. Hold-over/-under values can be displayed as the adjusted range, the relative angle, or in MOA/Mils to enable fast click adjustments to riflescope turrets.
Leica employs an open-bridge/dual-hinge design that makes the Geovid lighter and easier to handle without sacrificing strength or stability. Protecting the optics and electronics is a magnesium alloy chassis that is lightweight and durable. The body is wrapped in a protective rubber armor that provides a slip-resistant grip. To withstand the rigors of the trail, the optical tubes are nitrogen filled and O-ring sealed to be waterproof and submersible, and resistant to internal fogging when moving through extreme temperatures and environmental conditions.
