Here is one that always bothers me bobbing around in the Ocean:

Am I doing a correct and fast breathe up, or am I dipping in to Hyperventilation territory?

I use my Suunto to time 2x down time, I wait, body relaxed, breathing deeply through my snorkel, or sometimes, face up. How will I know if I am correctly replenishing, or instead fooling with my CO2 triggers? Typically, with my standard breathe up, I feel ready to go again at 1x downtime, the other 1x is a boring, Suunto looking wait.

I should probably add that my typical dives are 1:00 to 1:30 in about 20M of water. I am fit, but not very experienced.

In pool work I have deliberately hyperventilated, so know the slightly giddy feeling. But don't notice it in the ocean. But then again, so many others senses are in play I doubt I would.

Thanks for the advice..
