The ultimate compact rangefinder with innovative technology.
For discerning hunters and precision shooters who demand maximum performance in a compact design, the Leica Rangemaster CRF MAX sets new standards. The most advanced technology and outstanding optical quality come packaged in a rugged, weatherproof housing for the toughest hunting conditions. An innovative Active Matrix MicroLED display offers unrivaled brightness and individual configuration options, while the integrated Applied Ballistics Elite® software including Shot Probability Analysis provides precise ballistic solutions in real time.
Three intelligent target modes enable reliable and precise rangefinding in a wide variety of situations – from small or close targets, to clearly visible objects, to targets that are partially obscured. High-quality optical components ensure a detailed, color-neutral and razor-sharp image. Thanks to Bluetooth® integration and extensive connectivity options in combination with the Leica Ballistics app, the CRF MAX is the ideal companion for modern, professional hunting and shooting.
