| Earlier this year I did a trip to norway, with a fair bit of deco racked up on the dives, and I wasn't impressed with the vyper profiles.
I felt that the vyper wanted me straight out of the deep and fizz off at 5, then 4, then 3m - on one dive the tide and wieght of the divers had dragged the buoy on the shot from the surface to about 8m and the vyper wanted me at 4m so wasn't clearing, which considering I'd done manually calculated deep stops and sensible ascent times left me a little unimpressed to say the least..
(I had a side mount with 50% so cleared the rest of the stops when we bagged off quite safely)
If I was going to replace the vyper I'd look hard at the other options and get loaners where possible to see how they work in the water |
