Does anyone use a D3? There have been some comments about avoiding the small suunto computers - not sure if this applies to this one....I know it is mainly a freedive computer, but it also has gauge mode like the others. I am wanting a dive computer - I thought the Vyper (wrist mount). But, I also do some freediving and thought a computer for this would be cool. One solution was to get the Stinger, that does it all, but the non-user replacable battery and some negative posts on this computer have made me shy away. I thought about just getting a D3 and using it as a bottom timer for scuba in gauge mode or do I need to get both the D3 and the Vyper? The cost of both could be a problem though. Thanks for any input.
