Suunto EON Steel
Before updating the firmware, make sure the USB is securely connected. The cable must not
be unplugged until update process is completed.
Watch the video on YouTube.
To update firmware:
1. Select Suunto EON Steel from the devices list in DM5 If you are also using Suunto
Moveslink, exit Moveslink before proceeding.
2. Synchronize if needed.
3. Click update and wait for the update process to complete. This may take 10 minutes or
more.
3.31. Suunto Fused RGBM
Suunto's decompression model development originates from the 1980s when Suunto
implemented Bühlmann's model based on M-values in Suunto SME. Since then research and
development has been ongoing with the help of both external and internal experts.
In the late 1990s, Suunto implemented Dr. Bruce Wienke's RGBM (Reduced Gradient Bubble
Model) bubble model to work with the earlier M-value based model. The first commercial
products with the feature were the iconic Suunto Vyper and Suunto Stinger. With these
products the improvement of diver safety was significant as they addressed a number of
diving circumstances outside the range of dissolved-gas-only models by:
Monitoring continuous multiday diving
•
Computing closely spaced repetitive diving
•
Reacting to a dive deeper than the previous dive
•
Adapting to rapid ascents which produce high microbubble (silent-bubble) build-up
•
•
Incorporating consistency with real physical laws for gas kinetics
In Suunto Fused™ RGBM the tissue half-times are derived from Wienke's FullRGBM where
human body is modeled by fifteen different tissue groups. FullRGBM can utilize these
additional tissues and model the on-gassing and off-gassing more accurately. The amounts of
nitrogen and helium on-gassing and off-gassing in the tissues are calculated independently
from each other.
The advantage of Suunto Fused RGBM is additional safety through its ability to adapt to a
wide variety of situations. For recreational divers it may offer slightly longer no- deco times,
depending on the chosen personal setting. For open-circuit technical divers it allows use of
gas mixes with helium - on deeper and longer dives helium based gas mixes provide shorter
ascent times. And finally, for rebreather divers the Suunto Fused RGBM algorithm gives the
perfect tool to be used as a non-monitoring, set point dive computer.
3.31.1. Diver safety
Because any decompression model is purely theoretical and does not monitor the actual
body of a diver, no decompression model can guarantee the absence of DCS. Experimentally
it has been shown that the body adapts to decompression to some degree when diving is
constant and frequent. Two personal adjustment settings (P-1 and P-2) are available for divers
who dive constantly and are ready to accept greater personal risk.
