Leica CRF 1600-B and CRF 1000-R Rangefinders
Leica has recently made some changes to its laser rangefinder lineup, with the upgrading of both of its rangefinder models. The CRF1600 has now evolved into the CRF-1600-B while the CRF 1000 has been upgraded to the CRF 1000-R.
Material – Unlike most rangefinders that are either made out of aluminum or plastic, the Leica CRF rangefinders feature a metal framework covered by a plastic housing reinforced with carbon fiber. This design is rated as waterproof up to one meter for thirty minutes.
Viewing - The CRF rangefinders both feature a 7x magnification which is higher than other vertical style rangefinders. Information is displayed by means of an auto adjusting red LED readout. These units also feature fold down eyecups for those with glasses and have a diopter adjustment range of +/- 3.5.
Yards or Meters – One of the biggest complaints previously was that earlier versions of Leica rangefinders had to be ordered in either meter or yard versions only. Fortunately, both the new 1600-B and 1000-R models are capable of measuring in both yards and meters with the 1600-B even capable of giving addition information such as holdover in centimeters or inches depending on which mode is selected.
Leica CRF 1600-B – The new 1600-B is capable of compensating for not only the angle of the shot, but also the temperature and atmospheric pressure. Furthermore this unit is equipped with 12 ballistic tables which the user selects from to best match his cartridge load/ combo. The user also chooses from one of three sight in distances 100, 200, or 300 (yards or meter, six total options). Once this information has been entered the unit is capable of displaying the output in three different ways: true horizontal range, units of holdover such as inches or centimeters, or units of adjustments in clicks either Mils or MOAs. Despite its maximum range the unit will only give these types of readings out to 875 yards for “safety reasons”.
Leica CRF 1000-R – While its 1600-B older brother received a laundry list of special features and functions, the CRF 1000-R basically received the addition of angle compensated readings when compared to its previous version. This version does not take into account temperature or atmospheric pressure when calculating the EHR, equivalent horizontal range, as Leica calls it. However, this model is capable of giving this angle compensated ranges from 10yds to 600yds, again with safety being listed as the reason.
CRF Rangefinder Comparison Chart
CRF-1600-B while not specifically stated it appears that line of sight measurements are given after the maximum of 875 yards is reached, and it appears that you can get the unit to display angle, temperature and atmospheric pressure if you want to use the information in your own ballistic calculator. Also, the three types of ballistic information available appear to have a minimum range of 100 yards, therefore it appears true horizontal range may not be available until ranges of 100 yards, if correct this would likely only effect those who might also use this unit for archery hunting.
CRF-1000-R – Since this unit is listed as giving true ballistic range out from 10-600 yards and is listed as for use both archery and rifle hunting, it appears to be the safer bet of the two if you plan on using the unit for archery hunting and need angle compensated ranges. Also, since the max range of this unit is 1000 yards we assume that after the 600 yard maximum on angle compensated distances is reached that the unit would return line of sight readings beyond that distance.
Magnification – When ranging at extreme distances both a steady hold and increased magnification are required to successfully range targets. However, as magnification increases so does any unsteadiness in the operators hand and the view can appear to shake. While most vertical style rangefinders have a 6x or less magnification the CRF’s both feature 7x, which is necessary for long range precision targeting but may be a problem for some users. Also, many long distance shooters prefer the flat horizontal style rangefinders as they often times provide 8x magnification and allow for a steadier two handed binocular style grip. However, the increased magnification and stability of these units come at the cost of a larger size and heavier weight.
Both these CRF rangefinders received meaningful updates over there previous versions, and perhaps equally impressive remained the same price as their predecessors. These Leica rangefinders are unique in that they are long distance high magnification models but of a compact vertical design. Strictly long range bench and target shooters would probably be better served by what we refer to as rifle shooting rangefinders, while many hunters could easily get by with a cheaper less powerful dual use rangefinder. However, for those hunters that need to shoot at extreme ranges, the CRF 1600-B and CRF 1000-R offer a nice option between the larger and heavier shooting rangefinders, and the shorter distance vertical style units.
