Andy- I guess we're both strokes - I bought a Nemesis II Nitrox about a year ago. I guess the name should have warned me - Nemesis was the Greek goddess of vengeance and punishment....but it had all of these neat features like multiple gas mixes and user adjustable settings. And, their brochure assured me that it had been tested by freezing it in a block of ice, boiling it in pots of water, running it over with a truck (would it be too bold to suggest that the test program could have included a bit of actual DIVING?) My first N2N worked perfect for exactly one week on a live-aboard dive trip during which I did 18 dives. The very next dive, on a local 200 ft wreck, it went tits-up on me - told me (while on the bottom) I had over 5000psi in my 3000 psi tanks, put me at the surface while I was still at my 20 ft stop and told me the water temp was about 100 degrees! Fortunately, this was a planned tables dive and I had analog gauges for everything - the N2N was just along for the ride (it died completely after I surfaced and NO - it did not flood). Cochran replaced both wrist and tank units, but the new computer has been acting screwey too - it reported (and recorded) an average water temp of 129 deg on my last dive, with max temp of 140. It does this a lot lately. The waters off Ft. Lauderdale are warm this time of year, but they aint that warm!!! I may be old fashioned, but it seems to me that if you pay about $1200.00 for a dive computer (computer + PC software + dial a mix) you SHOULD get a quality piece of equipment. Seems to me that Cochran ought to quit screwing around with rebreathers and other new stuff and devote his energies to eliminating the *OBVIOUS* quality problems in his existing products (considering the lack of reliability of the N2N, you couldn't get me to use a Prism at gunpoint). I continue to carry my EDGE on all dives because, say what you will about its relative lack of conservatism, it is one of the most reliable pieces of gear I have ever seen. I also carry tables and dive watch on every dive - and tech dives are per preplanned tables - the N2N is pretty much always just along for the ride because, frankly, I don't trust it. And THAT is a goddamned shame!
