DCIEM Unlock Code

DCIEM UNLOCK CODE

SKU: 10055

Unlock the DCIEM algorithm for commercial diving on your existing compatible Shearwater dive computer.  

The Shearwater DCIEM diving algorithm is based on the Kidd/Stubbs serial decompression model developed by the Defence and Civil Institute of Environmental Medicine (DCIEM).


  • The DCIEM model has been tested by the Defence and Civil Institute of Environmental Medicine with thousands of Doppler evaluated dives assessing bubble formation.
  • DCIEM is available on the Peregrine, Peregrine TX, Perdix 2, Perdix AI, Nerd 2 and Petrel 3 in single gas Air and Nitrox modes only.
  • Access the Buhlmann algorithm and the DCIEM algorithm on the same dive computer.
  • Switch between diving algorithms while on the surface.

DCIEM FOR COMMERCIAL DIVING

DCIEM

Shearwater’s DCIEM algorithm implementation is suitable for commercial divers where regulations allow. You must always follow local diving guidelines and their rules for using dive computers.

Shearwater’s DCIEM implementation does not produce repetitive groups or repetitive factors, instead the DCIEM algorithm constantly tracks the diver’s tissue compartments even between dives. There are many advantages to using a dive computer over tables, including:

  • Increased dive time on multi-level dives and repetitive dives
  • Flexibility during decompression stops
  • Automatic electronic dive logging
  • Built in dive planning

ACKNOWLEDGEMENTS

Shearwater has worked closely with the Royal Canadian Navy to ensure our DCIEM algorithm implementation is true to their model. We would like to give credit and thanks to the Royal Canadian Navy for their work on developing the DCIEM decompression model but note that they are not responsible for our implementation of the algorithm.
