- Page 3 YOU REALLY ARE RISKING YOUR LIFE WITH THIS ACTIVITY. W ARNING Shearwater computers have bugs. Although we haven’t found them all yet, they are there. It is certain that there are things that our computers do that either we didn’t think about, or planned for them to do something different.
- Page 4 Shearwater has worked closely with DRDC Toronto to ensure our DCIEM algorithm implementation is true to their model. We would like to give credit and thanks to DRDC for their work on developing the DCIEM decompression model but note that they are not responsible for our implementation of the algorithm.
- Page 5 Divers who are accustomed to other decompression algorithms may be surprised at the conservatism of the DCIEM algorithm. The built in NDL and decompression planners will run DCIEM when enabled. This is a good tool for understanding the effects of the algorithm on NDL and decompression requirements.
- Page 6 No, if you are a certified diver comfortable using a dive computer you should not notice a practical difference in how the dive computer operates. The DCIEM algorithm is more conservative than some other algorithms, so it’s important to plan your dives and prepare accordingly.
- Page 7 Bühlmann ZHL-16C tissue compartments, exactly like it does when running the Bühlmann decompression algorithm. We chose to leave this graph in place while the computer is running DCIEM for interest and so tissue loading could be compared. The tissues represented in this graph have no impact on decompression calculations when running the DCIEM algorithm.
