As others have said in various ways, the profile you propose should pose no significant problems. In the future, however, if you are driving to altitude after a dive you might consider planning the dive as an altitude dive. You just use equivalent depths assuming you are diving at the greatest...

I usually attach my regulator to a tank, jump in the water and rinse it for about an hour and then take it off and hang it up to dry.

I seldom use bolts to assemble my doubles. I just buy stainless threaded rod, cut pieces to length and dress the cut ends with a file.

I think a remote air intake is a requirement. You need to consider not only the exhaust of the gas powered compressor but also the boat exhaust. You need to be able to move the air intake around so that the intake can always be located upwind of all exhausts.

Good hoses do not just blow. Perhaps, it might be a good idea to give your equipment a visual check before relying on it for life support.

Stripping and/or painting tanks is a waste of time and energy. Leave them alone. Nobody cares what your tanks look like. Make them look pretty and everyone will know you are a new diver. After a few days diving with them they will be all banged up again anyway.

I have found that most problems of this sort are not the fault of the equipment. First, visually check the mouthpiece and case for tears and cracks and then do a vacuum check. Once you have verified that there are no leaks then think about how you were using the regulator. If the regulator...

There is little difference between the MIK20 and the MK25. Probably most MK20's out there have been upgraded to MK25 anyhow. The G250 is a great, high performance regulator that uses a relatively standard cofiguration. Parts are easy to get and most technicians are familiar with servicing...

If you really want to be devious - Instead of the flare, try taking a small stainless clevis pin and a bent up stainlesss cotter pin and shoot them into the offending boat's main sail with a sling shot. They will fall to the deck and have the entire crew wondering what piece of rigging is...

You're right, and the winner doesn't even get to keep it. It is, in effect, a traveling trophy.

Actually I have quite a few cups from my racing days that I can and do drink beer from. You are quite right, though, A protest flag is about the only thing these guys fear. In order to get a competitor to protest someone who is violating your rights you need to educate the competitors. Once...

There is no legal requirement for a boat to maintain any distance from a navigational aid. In fact, boats often come within a hair's breadth while navigating around them. The only prohibition in the law is that a vessel may not tie up to a navigational aid. The best way to handle sail boat...

You say that the regulator freeflows when you remove it from your mouth. Are you holding it with the mouthpiece down, horizontally or up? If you are not turning the mouthpiece down as you remove it from your mouth, you might expect a precisely tuned regulator to free flow. If, however, you...

There is only one known wreck off of the Great Lakes Naval Training Base. It is the wreck of the side-wheel steamer, "Seabird." She burned to the waterline and sank in the late 1860's. She lies in 28 feet of water about 3/4 mile off shore just north of Great Lakes harbor. That is a bit too...

I have had dozens of freeflows and witnessed hundreds more. The key to the successfully handling a free flow when one has only one gas supply is to be constantly aware of the operation of one's regulator. the time from when a regulator just starts to slowly bubble during the exhalation phase...

Even without bubbles to obstruct vision, it has been my experience that divers in an out-of-gas situation often loose all perception of the outside world. They are focused intently and solely on their breathing, or lack thereof. I believe there is only way to approach a diver who is in an...

I'm not really sure where I heard that phrase first but it may have been from Joe. I did my TDI / SDI instructor training / cross-over with Joe Odom and Brian Carney back in the mid 90's.

Try "The Urinators' Shop." Look it up in your Funk and Wagnels.

Safety and practicality are what is important. It really does not make any difference what set of units are used as long as they are used consistently. All team members must be using the same units for optimal communications and optimal safety. Remember NASA and the Mars probe. Different...

It really does not make much difference what system you use, as long as everyone in the team is using the same system. NASA will attest to that.
