Been there, done that, on my first "discover scuba" dive, no less. Just make sure you keep the reg in your mouth. Your reflexes will handle the rest.

This. Salt water is 2.5% (approx.) denser than fresh. Take 2.5% of your total weight (you and all your gear), and add that to your fresh water lead requirement.

I've never heard of the term "Sport" requiring a team, but some people (like my brother) define it as a competition with objective criteria for determining a winner. So he leaves out gymnastics, ice skating and diving, for example, while track and field, various team sports, etc are included...

Just out of curiosity, where was that? I am in RI too. Though I normally dive with a buddy, I am starting to gear up for solo diving since I have such a hard time finding buddies in the colder weather.

I was thinking the same thing...

If you're floating on the surface waiting for the boat, do you leave your reg/mouthpiece in?

When I'm floating on the surface with my BC inflated, I'll take the reg out of my mouth if conditions permit (waves, mainly), but I put it back in before climbing up the boat ladder or walking up the beach slope, especially if it's rocky or slippery. I don't want to fall with my head possibly...

If you look into it, BMI charts are only (reasonably) accurate and useful for people who are NOT physically active, and were never intended to be a measure of fitness for active people. Some one who does a lot of weight lifting will have a higher muscle mass for a given overall weight and may...

Thanks for the info on the breathing. I have a personal (non-commercial) SCUBA lobster license here in RI, so am legal in catching a few while diving. Unfortunately, I haven't found any that were legal keeper-sized yet...

I spend quite a bit of time head down, looking under rocks for lobster, or taking pictures of things; it would be interesting to see how it responds to those situations.

I have dived with Giant Stride on occasion, but my main shop is The Dive Shop in Newport, since I live closer to them. Both have good operations, but Giant Stride seems a little more professional. The difference is not big, though, and I've heard Hymie in Newport recommend that people go to...

Good points here. Disposable contacts (either daily or extended wear) make using contacts while diving a much more reasonable argument. They aren't expensive to replace, you don't have to have glasses along on the boat, and it's easy to carry spares around with you. As I said earlier in this...

Yes, they will.

You don't have to do it all in one day, and hopefully the number of people who get bent is relatively small. When DAN does research at Duke University, chambers, they spread it over several weeks. As long as the various environmental conditions (temperature, dive profile, workload, etc) that...

The superstructure of the old bridge was sunk there as an artificial reef, after it was blown up a few years ago.

You don't have to run them all at the same time...

If they had a chamber on site to allow for immediate treatment of DCS, I'd probably be willing to volunteer for such a study...

Yup, it definitely gets easer the more I dive.

Yup. Opening your eyes under water with contacts in, is no big deal. I wouldn't want to have to swim very far because they'd probably wash out, but other than that, there's no issue.

1. Certification fees, primarily. I don't think replacing lost cert cards should be one; card replacement should be at (at most) cost, IMO. 2. Administrative overhead, insurance and legal costs; maybe some research on injuries and deaths. 3. Monitoring and (hopefully) enforcing standards...
