I cant begin to tell you how good the VR3 is. I love it. Yes its expensive and Yes it takes some getting used to but it is a veeeerrrrrrrry clever bit of kit.
My dive buddy Andrew was not convinced but he only lasted a couple more dives with him on tables and me waving my cleared deco VR3 in front of his eyes and he went out and got one.
For nitrox only diving its just too expensive but for two or three gas mix diving using say air as a bottom gas and two deco mix its worth its weight in gold (and its very heavy) When you get into Trimix there is the VR3 or the equaly expensive Explorer and i would go for the one thats used on just about every non DIR deep diving expadition in the world.
You still need a seporate bottom timer and depth gauge and you still need tables for bail out but apart from that enjoy the dive and dont be restricted by fixed table multi level dive plans.
Personaly I think the down load packet is pants so if you have a Vyper or other Sunnto keep it as a depth and bottom timer and use its down load package to record your dives. Proplanner is OK but bloody awful to use at the moment I would use Decoplanner to plan your bail out tables.
DO NOT bother with big graphics. You will get used to the small screen and big graphics does away with the very very important Time To Surface figure on the display screen. Mr Gurr dives mainly CCR so the PPO2 reading was aparently more important to him
Do get the screen guard.
Soooo if you havent guessed my advice is bite the bullit and get the VR3.
As long as your unit is reliable (Andrew and My units have been great so far) and as long as you do a fair bit of deco diving will love it.
