Highest precision in distance determination

Leica Rangemasters have been an essential aide for field sportsmen for many years now. They combine high-quality optics with durable mechanics and complex electronics in an extremely compact design. Like all other Leica rangefinders, they always meet precise parameter determination standards – anytime and anywhere. This way, they support every hunter and provide answers to of his essential questions. In a record-breaking time of 0.3 seconds, Rangemasters determine all the important parameters with maximum precision and ensure the necessary safety for accurate shots. Thanks to their compact form, they fit easily into any pocket.

Ballistic rangefinding has never been easier: Create your individual ballistics profiles quickly and conveniently with the Leica Hunting App, save them and put them to use whenever you like. With the Rangemaster CRF 3500.COM, precision long-range shooters and hunters in all environments receive precise, reliable rangefinding up to 3,500 yards – in fractions of a second, at the touch of a button and on any type of target.

Maximum ease of use

Distance determination with only one hand

Precise rangefinding, simple and compact: The unique combination of outstanding optics, state-of-the-art measurement and laser technology, and extensive ballistic functionality in a compact, rugged design makes the new Rangemaster the most versatile rangefinder in its class.


Distance determination with only one hand

From the very beginning, the Leica CRF Rangemaster series was designed with an uncompromising focus on ergonomics and compact size. It seems to nestle into the palm of the hand. This ensures a comfortable hold and allows the measuring button to be pressed easily, thus providing the foundation for precise, clean measurements. The Leica Rangemaster is incredibly versatile, powerful and rugged. Thanks to its compact, sturdy design and a weight of only 220 g, it’s the perfect companion for left- and right-handed hunters in every hunting situation.

Sharp in the extreme

Brilliant and razor-sharp images from edge to edge

Even at dusk and in difficult light conditions, the images remain exceptionally clear and razor-sharp. The large field of view and 7x magnification make it quick and easy to detect the target. The sharply defined LED display with automatic brightness control guarantees simple and reliable reading of the measured distance and the ballistic output values – in all situations and at all times.
