The DCIEM algorithm has been validated by the Defence and Civil Institute of Environmental Medicine with thousands of Doppler evaluated dives assessing the formation of bubbles which are thought to contribute to decompression sickness.
Every diver can use the DCIEM algorithm. It is the preferred diving algorithm for many commercial divers, and several Navy’s throughout the world including Canada, Australia, Italy, Norway, and many more.
You can buy a Shearwater DCIEM computer, or a DCIEM unlock code for your existing Shearwater computer, from your Authorized Shearwater Dealer
