The rule of thumb is to account for the difference in specific gravity of salt water and fresh water. If you are diving the *same* equipment (wet suit, BC, tank, etc. all identical), take the TOTAL weight on land of EVERYTHING that you are wearing into the water, INCLUDING yourself and your...

Another reason back inflation BCs may tend to tip a person forward is trying to lift too much of the body out of the water. Assume that you are properly weighted and neutral in the water. Once you lift your head entirely out of the water, you have at least about 10 pounds weight in air, and...

Since when do we learn only from our own experience? I thought the whole point of having a brain is that we can learn from the experience of others, and exercise judgment about the increased marginal risk (however small) of adding additional potential failure points to our equipment. I thought...

Here's another site that is very well put together from a diver in Tucson (which I just found by searching this forum), with other useful information about traveling to and diving in San Carlos: http://www.vancesystems.com/scuba/

Depending on how much stuff you are hauling with you, you can take a bus or taxi from Guaymas to San Carlos. The same bus service that is taking you to Guaymas may also serve San Carlos, so you might want to check with them. I think a taxi should run about $15-20, but I haven't done it...

I have been looking at a BP/W setup, and have been asking some of the same kinds of questions for a little while. So I'm no expert, but here's what I have been doing. I suggest checking out the pretty pictures and the little blurbs that the manufacturers publish on the internet about their...

But being "mistaken for a snack" takes in a lot of territory when you're talking about certain sharks, because some of them are inclined to sample just about anything. In fact, I think that's probably why tiger sharks worry me more than great whites; I don't think the latter commonly mistake...

Bob (Grateful Diver): "Sad to say ... we had one of those here a couple years ago. The fellow died with a full tank of air, a 45-lb weightbelt wrapped around his waist, and a "buddy" who didn't even know what happened till he completed his dive." And I think that illustrates that it isn't...

I saw a diver checking to make sure his buddy's valve was open by reaching out and unscrewing the yoke on the regulator. He stopped when I said "that's the yoke," but I was half tempted not to say anything because I was curious to see what would happen if he kept going. And he knew better, but...

You might want to post your question to the Arizona SCUBA sub-forum down there in Dive Clubs and Regional Travel, where there are a number of people who enjoy lake diving. I would pay special attention to people who have been diving (and boating) there *recently* - because the long drought on...

What I missed was not a skill so much as a little better awareness of currents and underwater geography. When I was skin diving, every trip back to the surface reminded me of where I was in relation to the boat, or the beach, or whatever. I never wandered very far without knowing it. Very...

I once saw a video of a skydiver who jumped out of an airplane without a parachute. He had a helmet with a little video camera mounted on it, and he did remember to put on the helmet and turn on the camera, so he shot the video of his own death. You could spot the moment when he realized what...

I dove from a smaller boat, and getting in the water was never a problem. I don't think a small ladder is likely to work for people wearing their gear, getting in *or* out of the water. If you have a small ladder, and don't have the room or inclination to replace it with something really...

http://www.flmnh.ufl.edu/fish/Gallery/Descript/Tigershark/tigershark.htm I have always associated them with the South Pacific (that big red blotch on the map in the article just linked to), where I have never been diving. You can see they occur along the Pacific coast of the U.S. and Mexico...

On the subject of statistics, I think most people believe things about shark attacks that just aren't true. The idea that people are at greater risk on the surface than on the bottom is probably false - more people get attacked on the surface because more people are swimming on the surface than...

I'm not a doctor, either. I don't know what you may already have done to look for information about this from other sources, but there is at least some discussion of the potential risks specific to diving here: http://scuba-doc.com/alertdiver2.pdf That seems to be assuming that most...

Strap fins and, more likely than not, a *smaller* boot than your street shoe size, but the only way to know for sure is to try them on. Don't try on a pair of boots and say they fit just right, even if you think they do. Try on the same boot in the next smaller size, or the next bigger...

Kgrover, I think it sounds a little ambitious, although I admire your enthusiasm. It looks like you're going to be in San Carlos for several days, so it may be possible to get in the required number of dives in the same trip, if the agency and your instructor will permit it (I don't know PADI's...

No. That's just the first three years. In the fourth year, the govt schools will not have to be graded, because the fact that they are run by the govt will be conclusively presumed to be evidence of their satisfactory performance. Only the remaining half of the schools still in private...

"Sorry, no buddy is going to get my nose in his butt no matter what. ..." Yeah, that's what the snorkel is for! With proper training and good placement of the snorkel, you can push your buddy all the way to the beach. And then replace the snorkel, of course. I think I'm generally on the...
