Suunto personal settings

[Adham Mostafa]

A question for the experts here:

The Suunto Eon Core has5 personal settings, from +2 most conservative to -2 most aggressive.
The manual was very frugal in describing the differences and there was no numbers to compare, I'm a PADI instructor and I do dive a lot during trips and courses, on the default mode I felt it is too conservative when compared to my late Suunto Vyper.
What's your input on the matter?
Appreciate it.

Unless you are doing 50m air dives I would expect the default to be similar to the vyper. Try both in DM5 and compare.

For medium deep dives which deserve helium, but without it, it might give longer stops. Having said that I did a bunch of dives recently with a buddy on one while I was diving 50/80 CCR and was not held down excessively. There was always cake left on the boat,

This certainly won't answer all your questions, but Suunto does have a bit more information available on the settings than what is in the Eon Core manual available here:

According to the graph the most aggressive setting allows 20 minutes on 30 meters dive which is what the RDP allows, have you seen any other depths graphs?

Can you fill me in here more, why would it be different on 50m on air than the Vyper?

THe Eon runs Suunto ‘fused’ RGBM not Suunto RGBM and it treats some things differently. Plan two 50m 30 minute dive stars in DM5, one with each (maybe you have to just switch) and compare.

I had a Helo 2 and used a -2 setting. Even at -2 the algorithm is still conservative IMO. I executed 60-80m dives regularly without problems.

Is it fused rgbm?

 

[ajduplessis]

Not sure. Even if you give it a name the details is not defined. Its some version of RGBM.

My simplistic understanding is that Suunto has 3 flavors of RGBM, Suunto RGBM, Technical RGBM. and Fused RGBM. Fused RGBM runs Technical to some depth, beyond recreational, and then switches over to Full RGBM. Vyper runs Suunto RGBM, HelO2 runs Technical, Core runs Fused. I would expect HelO2 and Core to behave identically until the Core switches over to Full. I don't know how Technical compares to Suunto RGBM on the Vyper.

Running the Core (or HelO2) at P-2 would seem to be reasonably liberal. @Diving Dubai has extensive experience diving an Eon Steel (same Fused deco algorithm) and some experience diving a Perdix at the same time. He has mentioned that the Steel at P-2 is very similar to running the Perdix at 45/95.

I have seen clean, 1st dive NDLs from an Eon Steel. They are quite similar to DSAT, another quite liberal decompression algorithm. I don't know how repetitive dives would differently affect the two algorithms
