My wife thinks it is excessive, but I bought a redundant computer. It is a hosed computer. My main one is wireless. (both same brand a sunnto D9 and a Cobra). I run the hose into the pocket of my BC, so it doesn't add a whole lot of extra stuff.
here was my rational. At the time I bought it we were planning a trip to Bonair and a Aggressor live-aboard. The cobra was $450, a fraction of the two trips we had planned. I figured that if either of our computers went out we would automatically have a back up that was "up to speed" with our dive profile.
Last weekend a buddy and I took a long weekend to Nassau. His computer went bonkers first day out. I switched it out with the cobra and he was good to go. so it paid off on its second voyage. I know buddies aren't suppose to share a computer, but I was always in the water first out of the water last and deepest, and neither of us gets anywhere close to the NDL. (Same with wife--I invariably have a slightly more aggressive dive profile--she seems to prefer being five feet above me rather than next to me, but we do seem to do a lot of walls.)
However, I do have a question. The cobra has a quick release. Does anyone know if I can dive without the quick release attached to a hose? Just with the computer in my pocket.
In otherwords if the quick release is detached is the unit sealed against water intrusion?
Then I could get rid of that extra hose and be a tiny bit happier with the arrangement.
but in any event, I consider that spare computer part of my save a dive kit. Along with tools, o-rings, straps, etc.
