 We're chatting with Dr. Michael Cassetta, and we're talking about underwater search and rescue. You know, Dr. Mike, I would like to know, I would like to understand, if I'm watching you dive and I'm watching you train or do your thing in real life, am I watching you with like a headband that has like a flashlight coming out of your head? In other words, what do you look like? What are the tools that you use to enable you to search underwater where it's dark?
