This is actually one of the hardest things to find any accurate info on. While DAN has some demographic info from injury reports and PDE, it is not very detailed for most divers. We're talking age, gender and smoker/non-smoker. AFAIK, the agencies will not release the information, though they...

That is really cool. You might want to find an antropologist at a University and tell them about it. They can usually get permission to remove artifacts, and then you can find out where/who/when it really came from. There have been major finds made by people happening upon something, and you...

I got to stage 2 once when a friend took me up to do aerobatics. It took me a couple hammerheads and cuban eights to figure out how to keep my eye on the horizon. Other than that, I was one of those jerks who ate curried goat on the way out to the dive site. On the other hand, I had to clean up...

Thanks for moving the thread, and thanks for the replies, I will check out those boats. I'm hoping to get a few students at the colleges to come with me, since most have not done any local boat diving.

Any boats people would recommend for one or two days of diving in the Channel Islands? I have a week with nothing to do before I graduate in May and move back to Chicago. This will be my last time to dive in SoCal for a while, so I want to do something special. Not too concerned with cost at...

I am somewhat partial to Xanadu, as I used to work there, and I believe they are the only operation that still does a shark feeding dive. The diving in May should be good, with decent vis (~60'-100'). Water temp, as mentioned should be in the high 70s. The pictures on...

Remember to check whether your insurance covers the transportation to a facility as well as the treatment. In some parts of the world, like the South Pacific, air evac costs can be well over $10,000, combined with treatment costs the total can approach $50,000. AFAIK, most dive insurance plans...

Older Suuntos would reset everything if you left the batttery out for more than 15 minutes, I think. I would try leaving the battery out for an hour or so and see what happens.

The places I have worked, the tip was usually split evenly between the crew. It is acceptable to tip at the end of a trip, after the last dive. If you think one DM was really good, take them aside and give them something extra and make it clear it is just for them. From experience in the...

I have been very satisfied with my stinger, but I would get a vyper if I was getting a computer today. The vyper is more flexible for mounting and the pc interface is less touchy than the stinger. The stinger is a royal PITA when it needs a battery change, since not many places can do it (I know...

You're going to have to talk to your registrar. Where I am, the scuba class can get you one PE credit, maybe another if you do advanced. I never even bothered trying to get my IDC to count towards anything since my school did not even recognize all my AP credits. I would not expect more than one...

I have seen the meat tied to a string that is in turn tied to a tree. It dies and the shell falls off, I think they only do this for conch shells that should look nice. Most of the ones I've seen for food prep have a hole punched through the shell, but that's as much as I know about the process.

You do it the same way. I do not find it any more difficult to remove and replace.

I actually believe the yellowing is a reaction to light, I assume UV rays. If you look at snorkels that have been displayed for a while in a shop, the silicone often looks yellow. AFAIK it will not be a problem. I've had masks and snorkels that were yellowed and did not have any problems diving...

What I think you are talking about are just deeper safety stops, but with a complete 3-5 minute safety stop as usual at 10-20 feet. Stopping at intermediate depths for a minute or two mostly increases off gassing time under pressure; in other words it slows the ascent. There are not any rules...

I don't remeber running into much flak at all as a 19 year old instructor. I mostly taught resort courses in the Bahamas, but did regular courses as well. You have to earn the students' respect, and being young, you may have to work a little harder to get it. Its fun though, and as I said...

If you are looking for some good diving in the middle of nowhere, check out Small Hope Bay Lodge (http://www.smallhope.com/). They are on Andros Island. I've never stayed there, but I did spend a good deal of time with the staff when I worked on the Island. Good guys, great diving.

Shops are not allowed to sell aqualung products on-line, if that's what you mean by site. Any shop that sells seaquest can get aqualung BC's, but they are being phased out in favor of seaquest. If you do find aqualung on-line, you cannot get a manufacture's warranty.

It is important to note that while DAN has many of the numbers on injuries and fatalities, including, experience, they are missing a very important pece: the total number of dives each year and total number of divers. Without these two things, any statistical analysis is not going to be worth...
