you don't get sunburned scuba diving the water absorbs the sun rays if i am 29 feet under the water i could lye their all day and not get burned also most likely you ware a suit so how can you get burned. i think the rickster is confusing diving and preparing to go diving
I have been trained by PADI and SSI. In PADI training an octopus is the whole air delivery system (which is what SSI calls it). In SSI, it is called the safe second and it is meant for your buddy. PADI never bothered to teach me the name of this. This is a bad question.
