First of all, I would like to thank Shawn for a very accurate portrait of the G7 BR2 product.
I've always been interested in the beam divergence debate. Frankly, I find the arbitrary concept of smaller is better very similar to the bigger is better argument in the cartridge selection debate. The intended application must be considered, and an understanding of the underlying science. I've always loved the comparison of the terminal velocity comparison of a 30-378 wby with a 165 Barnes TSX vs the 7mm Rem Mag and a 168 Berger VLD.
To have a discussion about the merits of beam divergence without discussion signal processing technology or FCC Class one requirements is fruitless.
SBruce's function test is a good idea. If there is no standard to judge by, test it. I'm happy to put one up, I doesn't do me any good to do it and report it. I'm not certain it passes, but from my experience with the measurement mode (Nearest in this case), I have high expectations.
I think a brief understanding of signal processing options is covered in the article at 6mmbr:
Look at the information about pulsing systems and target priority. The G7 works because the beam is bigger and you can remain on target even without a rock steady rest. The bigger beam allows more power output while staying class one eye-safe. The most other RFs send out a burst on firing, the G7 will continuously sample and add signals to detect targets for up to 5 seconds. Target priority is the key to difficult shot situations. We see it, detect it, and the measurement mode allows us to select which one you are after.
For example, if we selected N for nearest mode (one button press to switch between measurement modes) we would return the hanging target, not the hillside behind. If it did identify multiple viable targets, an indicator shows it, and the different ranges are shown. You will have the information available that you need to make the shot.
The device uses a 905nm laser diode. The expensive models achieve better ranging performance because they use a 1550nm diode which is more expensive and is not limited on power output to remain eye safe.
Bottom line, this device was configured to work with nearly any scope turret or reticle system (sorry Mrad guys) and give a sophisticated ballistic solution with a single button press. Very precise and very easy to use.
The ballistic calculations match the G7 program calculations available here on this forum or at our site gseven - Home
Learn to use the Trajectory Validation feature and the G7 drag model standard (if necessary) to fit field performance data. If you like the calcs online, the RF matches exactly. By the way you can use your G7 ballistic coefficient in the RF if you prefer.
