Wow!
I posted this thread and watched a little TV before heading to bed, hoping I'd get a response or two. I fire up the 'puter this morning and discover a HUGE trove of information. Thank you ALL!
I'm doing this on a laptop, so I'm not going to try to multi-quote all the fantastic suggestions.
One person asked about my target audience. I'm intending for this to be a medical techno-thriller, appealing to a wide audience. I wanted to add the diving element into my novel because, no surprise, I love diving and want others to see my passion in it as well. So, while I don't want to lose readers delving into a lot of technical diving description, I also don't want to lose any divers reading this book and thinking "No way, this is total BS! Besides, that guy is diving with neon yellow fins, so he's gonna die!"

One of the biggest turnoffs for me, and this is such a trivial detail, is when an author refers to a magazine as a clip. After that, it's hard to take the author seriously when reading about anything firearms related after that. That's why I want to, ahem, do it right, on even the smaller parts of the story.
Since everyone has been so generous with their time and knowledge here, I'll expand a little on my general concept. That might also help refine what I'm asking. Following the adage to "write what you know," my character "Zach" works in infectious disease research. While on vacation, he and his tech/wreck instructor decide to dive this newly discovered wreck, a freighter. Zach is an experienced recreational diver, and has finished his advanced wreck diving training. His mentor found out about this wreck from some of his fellow tech divers. He thought Zach might find this to be a good way to gain experience. Much of this is backstory here, and may or may not make it into the final cut.
Anyway, while exploring an interior part of the wreck, Zach finds a crate of old vials, similar to what he's seen at work in their reference collection. Is that Cyrillic writing on the vials? What are they doing in a freighter in the Gulf of Mexico? Hhhmmmm, the plot thickens!
Zach takes the vials back to his employer (there's a reason for this that will come out as part of the plot) and this discovery will drive the rest of the novel.
At this point, depending on how the story develops, Zach might have to re-enter the wreck to find more samples. That, right now, is where the climax of the story will be.
So, that's why I was asking about the technical aspects of wreck penetration. I want to do it right, and let my non-diving readers get a glimpse of what we do and love.
Thanks again, y'all, an I truly appreciate your help! (And yes, I actually dive with bright green fins. Just ask KWS. )
