What is the beam width divergence of the Gunwerks G7 BR2
Lots of discerning customers won't spend $1600 without knowing this specification.
2 x 4 milradians. So, bigger than the Swarovski Laser Guide, which is round shape and 2 milradians. Not sure which dimenion is horizontal/vertical on the G7. Pretty big divergence, but I'm not sure how often these guys plan on shooting much beyond 1K. This has been one of my main concerns with this unit. Perhaps the near/far targeting mode can help with this, but I just don't see when a large beam divergence is ever going to be a good thing. Until I can afford the new Swarovski bino/rangefinder combo, I'm sticking with the smaller divergence and rectangular shape beam that Leica has.
Good article that discusses beam divergence/shape issues a bit showing what happens with this, although a bit out of date. Note the 2.5 milradian width x .5 milradian height of the Leica beam and the issues later on with the large beam divergence of the Swarovski Laser guide.
Page 6 of this Swarovski Training Document for the EL Range shows a beam divergence of 1.5 milradians by .5 milradians. Now that is pretty doggone good beam divergence and shape.
Not sure what the Vectronix units are doing...
