Do you want to check your math on the second half of that statement?

I don't know, just got back fro a nice steak and plenty of Beer. But if I remember correctly 33' of sea water is one atmosphere, so you double to 2 at 33. to double again you would have to add three ATM to get to four ATM, so add 99 to 33? OK, so that's what 132'?
I'm boat shopping, supposed to be having a good time and your wanting me to do math? I suck at math
Maybe my math is screwed up, point is you can hurt yourself at relatively shallow depths, you don't have to be deep to embolize

Sea level = 1atm
33ft = 2atm
66ft = 3 atm
99ft = 4atm

twice 1 = 2
twice 2 = 4

I concur that shallow depths can be dangerous.

Have fun looking at boats.

Sorry to be a nag about the numbers.
