Some areas of your body absorb gas faster than others.

DCIEM Sport Diving Tables

Tt looks simple at first; Table A: Your name or email address: Table C gives you a no “D” limit for a Repet dive, taking into account residual N2 from the first dive. Outline of Decompression Theory.

Time and depth dive you a “Rep. Don’t plan dives with these tables unless you learn proper proceedures from someone familiar with them.

How do you read DCIEM Tables??

No body can figure dcem out. The compressed air, which we inhale during scuba diving, contains nitrogen and oxygen at the rate of 8: For example, at 30 ft, if you stay tablee for 45 minutes, on these NAUI tables your repetitive group would be B, on the DCIEM tables, there is no 45 minutes at 30 ft, so you’d use 60 minutes and your repetitive group would be D.


Yes, my password is: Search Media New Media. If you multiply the repetitive factor obtained from table B, by the actual bottom time of your Repet dive you can then obtain an “Effective Bottom Time” or EBT which you can use to re-enter table A.

Its mission is to enhance the safety and effectiveness of Canadian Forces personnel in the way in which they interact with their equipment and the way in which they function in difficult environments.


Different filling times result for each compartment depending on depth and time. Repetitive Factor and depth give you the No-D limit at that depth. Nitrogen pressure in compartment.

Tabes, I’ve have some time to compare the two.
