CRF Rangemaster 3500.COM



Product Overview

Long-range hunters have the information they need for accurate shots with the Leica 7x24 Rangemaster CRF 3500.COM Laser Rangefinder. The device connects via Bluetooth to the Leica Hunting app on your phone or Apple watch to upload the ballistic profile of your ammo, and takes range, angle, and weather into account to suggest impact point correction in MOA or centimeters. It can also be used with an optional Kestrel Elite weather meter. A simple one-button interface provides critical ease of use and a red LED display clearly shows the ranging information in your line of sight in an uncluttered layout. An ambient light sensor can automatically adjust the display brightness so you'll always be able to clearly see the information without overloading your vision, or you can manually select from one of five intensity levels. Designed for durability, the housing is made of a lightweight and durable carbon-fiber-reinforced ABS plastic, and weighing in at under seven ounces, the Rangemaster CRF will be a valuable addition to your kit.
