Gunwerks G7 BR2 Rangefinder Field Test
Like most new gadgets in a guy's hands, when one is done playing with all the buttons it's time to get the directions and actually learn how everything works. I found that the learning curve for the was fairly short, and after a few minutes I was able to navigate the functions fairly easily. I noticed quickly that the Gunwerks G7 BR2 Rangefinder is different than most rangefinders.

The Gunwerks G7 BR2 Rangefinder


The G7 BR2 Rangefinder has a complete ballistic calculator powered by a G7 ballistic engine built into it, not just generic ballistic profiles but an actual ballistic calculator that allows you to enter your specific bullet characteristics. The G7 BR2's ballistic calculator gives you shooting solutions in 3 modes out to 1400 yards: BDC mode (Bullet Drop Compensator), which is configured to work with custom BDC turrets, MOA mode, which gives shooting solutions in minutes of angle adjustments, and inches mode, which gives you inches of hold over.

The Gunwerks G7 BR2 Rangefinder allows you to enter up to 5 different cartridge profiles and save them. Each profile allows you to enter muzzle velocity, sight height, and ballistic coefficient, and, in BDC mode, the turret's calibrated altitude and temperature. The rangefinder then measures air density, incline angle, temperature and range. Then, the G7 BR2 gives a true real time shooting solution in a BDC range for your custom turret or MOA adjustments. It can also calculate the inches of holdover if you select that mode. As if that wasnít enough, the Gunwerks G7 BR2 Rangefinder will also calculate wind compensation in MOA for up to a 50mph wind.

Now that I was familiar with what the G7 BR2 Rangefinder was capable of and how it worked, it was time to start testing this thing. First, I ranged everything I could find just to see if I could get a range. I live in the city and there is an endless supply of objects to range. I ranged cars, building, trees, birds, dogs, pretty much everything you can think of in a city. The Gunwerks G7 BR2 Rangefinder ranged up everything. I was able to get ranges as close as 10 yards and as far away as a mind blowing 2500 yards. But the city is full of reflective targets. So, it was time to move on to other terrain.

Next, I took the G7 BR2 Rangefinder to the open plains, where most rangefinders rarely range objects beyond 400 yards. I was getting open prairie readings of 2000 yards on bushes and antelope. This is where I started to play with some of the rangefinder's other functions.

The Gunwerks G7 BR2 Rangefinder has a nearest, farthest and continuous mode. Nearest mode allows you to range the object closest to you. For example, I ranged a lone antelope on the prairie at 1400 yards. The rangefinder is capable of ranging beyond the antelope but in closest mode it ranges all the targets in view and displays only the closest range. The G7 BR2 Rangefinderís closest mode is perfect for this scenario with the antelope on the prairie, where there isn't much of a profile for the laser to reflect off of, and if you were ranging the wrong object it could be the difference between a hit or miss.

The G7 BR2 Rangefinder's farthest mode allows you to range the farthest object from you. For example, you see a deer standing through some bushes. You range the bush and it is at 500 yards, but you know the deer is farther back in the bush. You set the G7 BR2 to farthest mode and it will range the bushes, then range the deer in the bush. Then the G7 BR2 will determine that the deer is the farthest object and give you the range of the deer.

The Gunwerks G7 BR2 Rangefinder's continuous mode allows you to scan the terrain and then the unit will give the various ranges of the terrain as you scan. I ranged a coyote as it was running away from me until it disappeared over a knoll. Itís easy to change modes on the G7 BR2 Rangefinder by pressing the mode button on the top.
