 Dive Timer with Multiple Alarms
Does anyone know of a dive timer into which you can program multiple alarms to remind you when to make a gas switch. I know this might seem a dull question but, I'm hoping to start a DSAT Tec Rec course in a couple of weeks and I'm wondering how people remind themselves as too when to make the gas switches in line with the dive plan?
Do you keeping looking at your plan and your timer/computer?
Do you all use computers that do this for you? |
