Always thought dive computers were overkill, but a recent silt-out proved me wrong
I used to skip the dive computer on shallow jobs, just relying on my watch and tables. Last Tuesday, we were fixing a valve on an offshore rig, and the water was pretty clear at first. Then out of nowhere, a big cloud of silt came up from the bottom, and I couldn't see my hand in front of my face. My buddy's computer started beeping like crazy, showing he was near his no-stop time. I had no idea where I was depth-wise, and it got real scary real fast. We had to feel our way up slow, and I kept thinking about the bends. That beeping noise probably saved us from a bad day. Now I get why everyone says to always use one, even on easy dives.
