I had an entry level Vortex rangefinder (?1000). It was stolen. I was very pleased with it. But, wanting a good monocular/rangefinder, I decided to get a Vortex 4000. With Vortex’s military program, I got 50% off advertised retail, now 40%, so that was some incentive to go Vortex again. Lifetime warranty, sees thru fog, rain, snow, plexiglass windows, camo mesh in Rhino blinds, excellent glass. Very pleased with the Ranging 4000.
If I had it to do again, I’d somehow try to experience a Leica as I suspect its a step up even though the Vortex 4000 seems hard to beat.
