          Comments about Newcon Optik LRB 4000CI Laser Rangefinder:

          Granted.. this unit isn't as good as the Leica Laser Locater Plus.. but then it costs a quarter of that unit. The optics in this are fantastic, the build is super sturdy and the battery life is nothing short of amazing (two weeks on very heavy use). The display can be hard to read at times (when it's dark out) but that's the only complaint I have.

          We own three of these, plus the lower model (1500) and they're all well built... if you're in the market for a professional class range-finder... this is your unit.

          Beware! This product doesn't work. Here's the test I commissioned.

          By Bart Chandler

          Comments about Newcon Optik LRB 4000CI Laser Rangefinder:

          Objective: Testing the NEWCON LRB CI, Laser Range Finder Binocular. Preparation: I used the newest NEWCON (supplied by you), an older Leica Vector IV, and a newer Swarovski 8x30 monocular. Tests were accomplished in actual field conditions. First Test: This test was on a herd of cows at 850 yards. The NEWCON was found to only measure a brown cow, and not a black cow on repeated attempts. It did measure the water trough they were around. Result: Brown color = yes. Black color = no. High Reflective = yes. The Swarovski and the Vector IV measured all with ease on the first try. Longer ranges: The NEWCON did give one reading to 1950 yards, which was the farthest we saw. This was on a rock face and at dawn (no bright sunlight). The Swarovski did 1800 yards in the same condition. The Vector... is no comparison, as it gave solid readings first time, day, night or overcast out to 4500 yards minimum. So it became obvious this test was between the $850.00 Swarovski and the $3800 NEWCON. The Leica Vector was put away. Small targets at long range: We have one rifle range that has 12x12 steel white targets out to 1600 yards. The NEWCON, after repeated tries in bright sun would be reliable to 1100 yards. The Swarovski would be reliable to 1550 yards in the same conditions. (The Vector was used to verify all readings). Other findings of the NEWCON: Claims: It's Owners Manual states: Measuring capability of 4000 meters on most objects and 9500 meters on highly reflective objects. I could not get over 1000 meters with this particular unit. Battery life, what I found: One new, 9 Volt Duracell was installed. It would not initiate the screen. So the supplied rechargeable Ni-Cads were installed. One lasted 10 minutes, the second lasted 12 minutes before the unit went dead. Main Screen: You must constantly toggle back and forth to a required setting. Example: There are 3 modes with 17 codes. If you are in range finding YARDS mode, and you want to go to inclination you must remember that particular mode/code, and enter it. Then, to go back to measurement YARDS you must scroll thru the modes, then find the correct code. It also takes a full 8 seconds (per the manual, more like 15 sec.) to recharge the capacitor on the laser before the next try at reading distance. Recommendation: If all that is required is a measuring device to 1500 yards, the $850.00 Swarovski is recommended. There are plenty and cheaper ways to instantly check compass azimuth and inclination, a wrist watch for example. The Vector IV still remains the unit in which to be judged by. The main judgment factor is it's overwhelming price at this time. In my opinion the NEWCON is not up to the task to take on the Swarovski on either optic clarity or range finding ability. It's price does include a nice hardened case, computer interface cable and disc though. Dave CheyTac, LLC
