It's not all blowing stuff up, some of it is repair work on ships, checking out how big the hole is when the captain parks on a rock and so on.
Dead rich, nice witty comment there
Yeah, not exactly sure how much it is, but divers get an extra bonus on top of their salary as it's one of the more dangerous jobs. And on top of all that, I get HSE diving qualifications without paying to do the courses (infact I get PAID to do it!), so can then go onto a commercial diving job.
