Ihave used the Leupoldrx3, andI have used my cousinsARC, and I would agree with FireDiver andWashingtonHunter that they are not worth the money. There is no doubt that a rangefinder should be a part of yourbowhuntinggear, but there is little to no benefit for a typical archer. If money is no object, I wouldsuggest the Bushnell because it is much easier to usethan the Leupold.
