Overview
Model 40547 in Leica's Rangemaster CRF PRO line is a compact laser rangefinder built for hunters and long range shooters who need distance and ballistics data in one handheld unit. It measures out to 2,000 yards through 7x magnification and adds an onboard ballistics calculator with wind correction.
Where many rangefinders stop at a distance readout, the CRF PRO adds an onboard ballistics engine with wind correction, plus Bluetooth links to BaseMap, Kestrel and Garmin devices. That makes it more of a ranging computer than a simple laser, though the upgrade to Applied Ballistics Elite is a separate purchase. The housing is polyamide ABS rather than metal, and waterproofing is rated to 1 meter rather than full submersion.
- 7x magnification with 405 ft field of view at 1,000 yds
- Accuracy of +/-0.5 m from 10 to 200 m
- Polyamide ABS housing built for field use

Who it's for
Hunters and long range shooters ranging distant game or targets are the intended user, especially those who want ballistics and wind data without pulling out a phone app mid-stalk. If you only need a basic yardage number, the onboard ballistics engine here is more than most casual shooters use.
Pros and cons
- Onboard ballistics calculator with wind correction
- Ranges out to 2,000 yards
- Bluetooth pairing with BaseMap, Kestrel and Garmin devices
- Applied Ballistics Elite requires a separate upgrade
- ABS plastic housing rather than metal
- Waterproofing rated only to 1 meter depth
Performance notes
The unit ranges targets from 10 to 200 meters with claimed accuracy of plus or minus 0.5 meters, extending out to 2,000 yards at longer distances, and gives a 405 foot field of view at 1,000 yards through 7x magnification. The built-in ballistics calculator applies wind correction on board, and Bluetooth lets it hand data off to BaseMap or paired Kestrel and Garmin devices for a fuller shooting solution.
