Rangefinder Binoculars Reviews & Field Tests: Ranging Performance Results

Not long ago, I helped build a 2,000 yard range for long-range, precision rifles. That range seems like the ideal facilities for a field test. It doesn’t get more real-world than this. Remember this isn’t a laboratory test … it is a field test. Although I was meticulous to ensure each model was tested in the same exact way and under the same exact circumstances, the targets and ranging scenarios varied just like they would in the field. By that, I mean the target shape, exact size, and surroundings were not identical at every range … just like they would ...

Rangefinder Binoculars Reviews & Field Tests: The Optical Performance Results

This is one of a series of posts about the results of field tests on rangefinding binoculars. Here are the models included in the test: Leica Geovid HD-B 10×42 (View Full Review) Leica Geovid HD Classic 10×42 Zeiss Victory RF 10×45 (View Full Review) Bushnell Fusion 1 Mile 10×42 (View Full Review) Bushnell Fusion 1600 10×42 Vectronix Vector 23 (View Full Review) Vectronix Terrapin (View Full Review) Leupold RX-1000i I hear so many people claim there is no way to objectively test optical clarity, because everyone’s eyes are different, so you just have to look through each pair for yourself. ...

Rangefinder Binoculars Reviews & Field Tests: The Models & Specs

Welcome to the largest and most comprehensive field test & review of laser rangefinder binoculars ever conducted. I tested almost every pair available in a variety of real-world scenarios, to see which had the best performance in the field in terms of both optical clarity and ranging capabilities. The results are based on over 10,000 data points collected from the field over 3 months of testing. I shoot in long-range rifle competitions, and some have known distance targets and some are unknown distance. For example, in the Steel Safari competitors have to locate, range, and engage 6 targets within 5 ...

How Do Rangefinders Work?

By understanding how rangefinders work, you’ll be able to employ them more skillfully in the field. This article should equip you with the fundamental principles. Laser rangefinders (LRF) all work using the same basic concept. The rangefinder emits laser beams at the push of a button. Those beams bounce off distant objects and the rangefinder’s high-speed clock measures the total time it took from when the beams left the unit until they returned. Since we know how fast the beam was traveling (speed of light) the unit can simply use that time measurement to calculate the distance it traveled, and ...
