The disclaimer that Buff is talking about (backup gauges) is something that computer manufacturers have to place in their manuals for liability reasons. I have logged some 300 hours on computers without failure. They are very reliable. The manufacturers that I have dealt with recommend aborting the dive should the computer fail. Due to the fact that recreational diving is no-stop diving, one can simply make an ascent to the surface. However, the more technical realms require deco-stops, meaning your life depends on the calculations of an algorithm in that computer. Therefore, back up computers and gauges is a life or death decision.
I would highly recommend a Suuto or Uwatec computer. If nothing else, nitrox compatability and user replaceable batteries are a minimum.
Cheers!
