During your Scuba training, were you taught to "Find the RAT" when learning about dive tables (rdp)? Do you remember what that means?

No but I found the cement bear on the Spiegel Grove once or twice. Does that count? On the Spiegel you find the bear, you move and hide it someplace else and then others do the same. Haven’t seen it in a while though. I think some tec divers must have taken it deep inside the ship.

Well you see you have so many of those left over bubbly things, and you figure how long you gonna be getting more of those bubbly things, and whey you put both of those together you have your total fizz.

Just joking around.

RAT is an acronym to help you remember something when calculating your dive profile...what does the acronym stand for and how is it used?

Progrower was correct. You "find the RAT" when calculating your dive profile on repetitive dives. Total Time is used to determine your pressure group on all dives after dive one.

From rashley: Well you see you have so many of those left over bubbly things, and you figure how long you gonna be getting more of those bubbly things, and whey you put both of those together you have your total fizz. Just joking around.

Left over bubbly things = RNT
length of time getting new bubbly things = ABT

Put those together and get your total fizz = TBT
