Stopped guessing my decompression stops with a $12 dive watch and a grease pencil
About 15 years back I was working a dock job in Morgan City and kept second guessing my stops because the console computer was on the fritz. An old hand named Ray showed me his trick, he taped a cheap dive watch to his wrist and wrote his stop depths and times on his slate before every dive. I started doing the same thing, planned every stop by hand off the tables and just used the watch to time them. Cut my surface intervals down by about 10 minutes a day because I wasnt waiting on the computer to think. Still do it on shallow jobs even now with a working computer. Anyone else still run a backup watch or have you all gone full digital?
Cutting surface intervals because the computer was too slow to think sounds backwards to me. That extra time on the surface is your body actually off gassing, not wasted minutes. I get the watch as a backup but planning stops by hand every dive just adds room for math errors when you're tired.
