Bel. I did three weeks of research and found the RX65 Pro to beat the V1 in EVERYTHING except the "over the hill X-Band", which the V1 beat it by about 100'. Everything else, from ranges to false detects, the RX65 Pro beat the V1 and Passport 8500 by wide margins.
Since then, Bel has released an even more advanced version of the RX65, which widens the lead over the V1 and Passport even more.
Some people swear by the gimmicky arrows of the V1. Who cares. If the detector goes off, slow down. It doesn't matter what direction they're coming from.
