From Outdoorsmans:

The Leica CRF 2400-R is the most prolific western hunting rangefinder on the market for good reason. Leica is legendary for its laser rangefinder technology, and at a price only slightly above the low-but-useable end, this is the best non-ballistic-calculating rangefinder you can buy, period.

From Leica:
The Leica CRF 2400-R allows distance determination of up to 2,400 yards. In addition, the Leica Rangemaster CRF 2400-R offers a new LED display for even better readability.

The LED display adjusts itself automatically to the ambient light and ensures even more precise, faster readability. Another remarkable feature is the extremely fast scan mode, which scans the environment and the relevant targets every 0.3 seconds and displays the required measuring results accurately. Up to 200 yards, the Leica Rangemaster CRF 2400-R provides the measuring results in decimal figures, enabling even more precise distance measurement.

Like its predecessor model Leica Rangemaster CRF 1600-R, the Leica Rangemaster CRF 2400-R determines the equivalent horizontal range (EHR) relevant for hunting up to a distance of 1,200 yards when required. With this feature, the Rangemaster 2400-R provides the practical angle-compensated distance, which is essential for an accurate long-distance shot. This makes the Leica Rangemaster CRF 2400-R a true all-rounder and provides hunters and long-range shooters with all crucial data.
