	I dive with the Cobra, the air-integrated version (Which I 
	would not do if had it to do over, just 'cause it's not
	DIR to have your computer on an air hose - I'd get the Vyper).

	I love this computer - everyting you need to know in a small,
	easy to read screen. Can be used in nitrox, air or gauge 
	mode, has a good PC interface (no Mac or Linux version 
	though, which is a drag).

	It's more conservative than a lot of computers, but IMO that's a 
	good thing - and it's really good at calculating the fact that 
	as you come up in the water column, you are decompressing. So 
	where my old Prodigy used to just decide I was saturated 
	when it got in the red and want me to be done, the Cobra 
	will count deco as I ascend and treat that (as long as I 
	don't violate it's preferred ascent rate) as part of my deco.

	It's really user-friendly. 

	Down sides - the manual sucks. You can't get it into Nitrox mode
	if you've used it on air (why does it even HAVE different 
	modes? It should always been in nitrox mode!), until you 
	are out of the water for 24 hours. It has a fixed ascent rate,
	which should be conditional on depth - if I'm at 200', it doesn't 
	mattter that much if I pop up 10'. If I'm at 25, it matters a lot. 
	The computer should understand that. 

	But all things considered, it's a great computer, I'd buy one 
	again. Until really good multi-gas decompression computers 
	come out and get afordable), this is the computer I'll use,
	both for rec diving and in gauge mode, for technical diving
	(or at least, I'll use the Vyper, which I hope to trade my
	Cobra for, eventually).
