Aloha Bill,
Yes i've been diving the new model VR3 for about 7 months now, it is by far the most advanced computer on the market, seems there isn't anything it can't do, altho I wouldn't recommend if for recreational diving, if your into tech diving it's the best, no lockouts, gas editing while on the dive, complete dive planner, and it will get you out of the water faster than any other computer, some of the other guys I dive with use the Diverite Ni-Tec, probably the next best comp on the market, the Vy-tec by Sunnto also a good comp but they seem to have transmitter problems, and the Abyssmal Explorer which I wouldn't take if someone gave me one, out of 4 here all have flooded or crapped out on the first or second dives, 1 gave a depth of 78 feet while on the boat (not a wreck dive lol) they was all sent back and repaired or replaced, all flooded again, you can find them for sale on Ebay if you'd really want one 8(
