Best Rangefinder – What The Pros Use

Best Rangefinder

This article covers the rangefinders the top precision rifle shooters in the country carry in long-range competitions. This is the first year I’ve asked about rangefinders, so it was exciting to see which brands these experts trust to give them an accurate target distances. The data is based on a recent survey I conducted of the top-ranked shooters across the country in both the Precision Rifle Series (PRS) and National Rifle League (NRL).

Pocket Rangefinder Field Test Showdown

Pocket Rangefinder Review

Over the past few months, I’ve been testing several high-end pocket laser rangefinders, like the new Vectronix Terrapin X and Leica Rangemaster CRF 2800.COM, alongside other popular, top-of-the-line models in the $1,000+ price range. I used all of them extensively, and took them out to the field to test their ranging performance side-by-side. This post summarizes those results and other noteworthy points about features on each one. An accurate rangefinder is one of the most critical pieces of gear for long-range shooting. A few years ago, I wrote a post that quantifies how much range uncertainty can impact hit probability. ...

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 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 ...
