 We do underwater construction. We do demolition, build boat ramps, mooring inspections, cable inspections. Depends on the job and the location. We do some salvage, debris removal, depending where it's at. Underwater when I'm working, I feel good. I feel like it's just a way for me to get to work. But at the same time, you have a lot of other things you gotta worry about. I have to worry about how much air do I have left. I gotta worry about my buddy, you know, because he's watching me and I'm watching him, making sure we're okay.
