Different SCUBA agencies - different approach:

Three instructors and their students are on board a dive boat in the middle of the ocean. There is a NAUI instructor, a PADI instructor, and an SSI instructor. Everything is going fine until the boat springs a leak and starts to sink.

• The SSI instructor says to his students: "Okay, we're in the middle of the ocean, so we might as well do our deep dive."
• The NAUI instructor says to his students: "Okay, we might as well do our navigation dive, so let's get our compasses out and swim towards shore."
• The PADI instructor says to his students: "Okay, for $25 extra you guys get to do a wreck dive!"
