> I have developed quite an interest in the DCIEM tables after reading Lippman's
> Deep into Diving. I recently saw an article in Underwater USA giving a US

> one. I just received my tables in the mail today and thought I would post the
> address to order them from. For anyone else with an interest.

> I paid US$ 9.95 plus $1.25 shipping and handling. The tables come on a very

> US Navy UDT-SEAL people and they just aren't normal people. Physically they
> are in outstanding shape. (Definitely in some other than normal mental state,
> but then look what they do...B-)  ) Any validation using people like them
> just doesn't seem like playing fair to someone like me. (I sit in front of
> a terminal all day with a phone glued to my ear. I am not at the peak of
> my physical conditon. Probably like a lot of you!) Lippman is very neutral
> on all the tables presented in Deeper into Diving but he does make it clear
> that the DCIEM tables are well validated and have the lowest DCS incidence 
> going. Validations were done by doing cold-water working dives and adjusted
> to eliminate some problems with the initial model.

> I used a copy of the tables (via Xerox magic) on a series of five dives over
> four days this past weekend. It is normal for us to make a 3 minute stop at
> 15 ft for safety. Only one dive was even moderately deep and that was to
> 72 ft. We only dove to the limit of the NAUI table on the 72 ft dive. Their
> were no major difference between the two tables in any dive except for the 
> 72 ft. dive. The NAUI table called for no stop. The DCIEM table called for
> a 5 minute stop at 10 ft. All dives were square profile calculations. We 
> tend to go to the deepest point to begin with on our dives and work our way
> back into the shallows. Stops are usually taken sitting on the bottom at 15
> ft, using a hangline off our float, or holding onto a kelp plant, and 
> establihing positive buoyance so we don't drag the plant down. We're very
> careful to use a big plant so we don't pull it loose. We didn't get bent this
> weekend but it would have been interesting to do a doppler eval after the 
> deep dive.
