Vectronix Vector 23 Review

This review on the Vectronix Vector 23 rangefinder binoculars is based on a 3 month long field test. It reflects the thoughts of 3 different precision rifle shooters as they used the product to observe and range targets from 25 yards to 18+ miles away hundreds of times. The full field test consisted of 8 different rangefinders, so we have a very wide view of what to expect in a good pair of rangefinder binoculars. This post is compiled from our notes of what we specifically liked or didn’t like about the Vectronix Vector 23 compared to the rest of ...

Rangefinder Binoculars Reviews & Field Tests: Overall Results Summary

Welcome to the largest and most comprehensive field test & review of laser rangefinder binoculars ever conducted. I tested virtually 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. This post is the executive summary of the results. I’ve already written other posts in this series of articles, which include exhaustive details about the ranging tests and results, as well as the optical tests and results. But, I’ll try to hit the highlights here. These results are based on over 10,000 ...

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 ...

MIL vs MOA: An Objective Comparison

MIL vs MOA Comparison Article

There are a lot of articles and forum threads out there comparing MIL and MOA, but most either aren’t objective or they’re overly complex. I’ll try to avoid both of those pitfalls in this article. Executive Summary A few months ago I asked Bryan Litz whether he personally used MIL or MOA. Bryan is an expert among experts in the shooting community, and after reading his books I’ve gained a respect for his scientific approach to decisions like this. His response was so concise and objective, I thought it could serve as the executive summary for this whole comparison: “You ...
