Rangefinders are interesting pieces of equipment. The Bushnell 800 that I once owned did not range properly as the "box" reticle shifted around and made for inconsistent and inaccurate readings; so did the Simons that I tried. The Leica LRF 1200 has worked Very well. However it works best in the early mornings, late afternoon / evenings and also with cloud cover. Does it work in the Rain, Snow, fog, or haze? No, it really doesn't. Battery life is severely restricted in the cold, and the mirage from heat really messes with them. What's the best range finder or one of the Best? The Leica Vector. Big Money though…
