Are you planning on using this chamber for treatment or some type of familiarization dives? It is doubtful the tank will have enough integrity to hold the pressure required for treatments (around 100 psi for TT-6A) and 26.7 psi for standard treatment tables (TT-5 and TT-6) Your compressor...

Good points Mike, I have to say I have had quite a learning curve seeing the recreational / scientific side of diving closer over the last few years. Military dives to 300 FSW for a working dive would require surface supplied at a minimum. The dives could be conducted as either mixed gas...

The missions are different, and I do not believe the original question was asking about who was better, just what portions of the training were applicable. I see your point but your statement about being able to judge because you have flown with or talked to military trained pilots is the...

Most of the dive shops in this area will sell air to a diver with a miltary certification (although during training most students do not have this yet) so if they want to dive on the weekend they just get a civilian card. In other areas of the country it really depends on who you speak with...

I only have experience with the "working" side of military diving (ships husbandry, hard hat, salvage, port construction and demolition, etc.) My last assignment was the Naval Diving and Salvage Training Center and I left in 2001. Currently when students graduate second class school (basic...

The SarTec is a reliable and durable unit. The unit would seem from appearance to be wieghty and awkward but it does not present a problem really, at most you may choose to add a viewport weight on the opposite side of the mask but I do not feel the need to. The oxycheck is a really nice unit...

I was an Army diver, when I attended training in 1992/1993 the Army still went through the Navy course. My last tour of duty was at the Naval diving and salvage training center 99-01 The Navy has a wide variety of divers, divers are also responsible for maintaining all of thier life support...

Most of the time we use "portable" dixie double locks (220 CF) to vent a chamber this size takes less than 10 seconds. (a mono placed would take even less) I have not seen an O2 seizure, and in fact only know a couple people that have (the convulsion was in a large military system, no head...

See an ENT, I have several diver friends that develop nasal polyps and had difficulty clearing thier sinuses. An outpatient procedure ( from reports painful though...) sovled the problem. Perhaps it is a simple physiological issue. Hope it gets cleared up! Jeff

I guess it depends on the individual chambers protocol but, chambers I have worked removed the patient from O2 (in a mono-place flushing the chamber with air) waited for the symptoms to subside, then traveled.

I have had problems replacing seals on suits that had silicone used on them in the past (remember typoons special silicone impregnated powder?) Anyone else run into the same?

The Navy Experimental Dive Unit NEDU has been cataloging data on nervous system damage (there is a staement on the back of the military dive qualification card that requests autopsy results be forwarded) Long bone necrosis is a confirmed malady that is a result of long term (career)...

Most chambers used for treatment or surface decompression (non-saturation / deep water systems) are rated to a depth of 190 FSW. These chambers normally have pressure relief valves that are set to operate at 100 PSI. Most of the newer single lock treatment chambers are rated to 60 FSW...

It depends on the cause of your injury, the severity of the injury, and the length of time it takes your body to heal from the injury. A barotrauma is an injury caused by pressure variations within an air space that has not had a chance to equalize. When this pressure gradient becomes severe...

Does you suit have the low profile valves? Why don't you call them and ask if they will send you the replacement valves instead of sending the whole suit in? (the valves are installed hand tight, it is a good habit to get into disassembling it to clean and lube anyway)

You can check with Florida DEP (Department of Environmental Protection), EPA (Gulf Ecology Lab does work diving all over Florida), Florida Aquarium (collection and interactive shows), or work within the University system. DEP, EPA, FL Aquarium, FSU, UF, Miami, UWF, all have established...

Hey Ben, double check your one way valves as well, they should be facing (folding) inward towards the inside of the oral nasal. They should not allow any amount of air to escape from the oral nasal into the mask portion of the mask. I have seen them installed incorrectly in the past...

http://www.adp.fsu.edu/HistoryOfDiving/index.html Here is some more information on the various versions out there. I would spend the money on a decent unit (AGA, M-48, EXO) and if you only need it for the one project sell it afterword.

That feeling like you can not catch your breath
