Leica Rangemaster CRF 2400-R

Leica is excited to announce the Rangemaster CRF 2400-R - our most powerful simple angle compensation compact rangefinder ever - an amazing 2,400 yards. That's 50% farther than its predecessor!

The new CRF 2400-R offers a newly designed LED display for even better readability of scanned distances. The new LED display adjusts itself automatically to the ambient light to aid precise readability. Another remarkable feature is the extremely fast scan mode, which takes measurements every 0.5 seconds. Up to a measuring distance of 200 yards (182 meters), the unit displays the results in decimal figures (to 0.1y), enabling even more precise distance measurement for archers. The CRF 2400-R determines the equivalent horizontal range (EHR) up to a distance of 1,200 yards (1,097 meters) when required. With this feature, the unit provides the practical angle-compensated distance, which is essential for an accurate long-distance shot. Thanks to its compact design it fits easily into any pocket – weighing just 6.5 ounces and is waterproof to 1m. The outstanding optics with a 7x magnification ensure the best image brightness and a wide field of view.

The essentials:

  • Ideal entry-level model with an output of linear, horizontal range (EHR) of 10 m to 1,100 m / 1,200 yds
  • Distance determination of up to 2,200 m / 2,400 yds
  • Excellent readability of LED display with automatic brightness control

    so far superior, other range finders should not be called rangefinders

    Posted by john white on Oct 16th 2020

    The Leica rangefinders are in a class of their own. No other brand can even come close to the quality, accuracy, speed and clarity of Leica rangefinders. I have used several different brands while hunting in Alaska, and the Leica is the only one that works in all conditions, returns the furthest readings, works every time in the rain, and is 100% dependable. Nikon and vortex are a joke in comparison, the next closest in performance to the Leica is the Swarovski rangefinder, and it is still not on the same level as Leica. (Review provided by ExpertVoice)
