Have not been able to find much good info on this. I'm looking for a good 3 gas deco dive computer. I have seen a few but some have not gotten that great of reviews. Now I have heard good things about the Hollis DG03 and was wondering what those of you think of it that use it. I also understand the cobalt does 3 gas too, but I prefer wrist mounted and wasn't lookin to drop $1200 atm. If anyone else knows of any other good computer's that will do 3 gas mixes i'd like to hear bout em
