I took my new Oceanic VT Pro to the pool yesterday to get it set up and enjoyed every minute of it. However I have one question. I looked through the directions on how to turn it off so I don't waste the batteries and there was nothing. I'm new to the whole dive computer thing and just wanted to make sure I'm not missing anything. I'll assume that it will turn itself off after the fly countdown is complete. Am I right? Any input is appreciated.
