They are good. Extremely fast lazer.
I bought them for the size and weight, as they are tiny.
I’d say glass is on par with Revic, but the right barrel is a touch darker. But clarity is same. No tint just touch darker, guessing its coating for the led read out. It took me a few times swapping before i noticed the difference though.
Lecia geo HD -R 2200 I couldn’t tell a difference glass wise, or light at dusk. GPO lazer is exponentially faster and more range, the Lecia did have a higher FOV though. With that said that Lecia is discounted. I ran against HD B and same glass but Geo laser was closer to GPO just a touch slow, but it is thinking of a solution though.
The Leica R I actually think has better glass then the Lecia pro/HD and is a touch better then GPO and Revic, but there is a very big difference in size and weigh of the Leica R vs 40mm GPO
If you want best glass Leica R
If you want lightest least bulky package with good glass GPO 10x40 @ 26oz.. it’s palm sized basically super
