My choice would be the current Swarovski with a couple upgrades. Optics are very good, a bino would be great but would add alot of weight and $$$
What I would do is change the aiming system to a fine crosshair retical with an open dot center. Similiar to the center of the Leupold TMR or IOR MP-8 scope reticle.
This would be lazer etched just like a rifle scope reticle and with the illumination option just like the upper end tactical scopes, Nightforce, IOR and such so the intensity can be adjusted for different light conditions.
No need for the extra hashes like the TMR or MP-8, just want the fine main crosshair with floating center dot.
More importantly, the rangefinder should be tuned to range the exact spot that the dot was pointing to!!!
Other then that I would change the power from 8x to 10x. More would be nice at times but in low light conditions you would run out of light for accurate ranging. 10x would be a good balance of higher mag power and good light transmission.
As far as ranging ability, the other night I was out shooting with my Dad. I was getting consistant +1650 yard readings inclined, bare grass hill sides. Repeatable as well.
I also got several readings at longer ranges and two that measured 1965 and 1967 yards again on an inclined bare grass covered hill side. The sun had just dropped behind some clouds but it was still quite light out.
I have no complaints about the performance of my Swari. Would just like a bit finer aiming system and a bit more power.
