 I'm the master diver for a 5'11 engineer dive team. So when you become a diver, we have four different levels of divers. We have a second class diver, that's what happens when you come out of dive school. The next level is to be a salvage diver. When you become a salvage diver, you get through a series of check-offs and earn to show your proficiency in different tasks. Today was one of those tasks. Today was a vessel inspection, so we set this up so that way we can have the guys go under and sweep a vessel and allow them to understand what the bottom of it looks like. So that way, if there's any future issues, they already know how to expect it and what's going on with it.
