Suunto Eon Core or Aqualung i770R Dive Computer

Actually, no. What prompted this particular tangent is me saying there's only one way you can change to a more aggressive deco schedule during a dive without appreciably increasing your risk, and that is if your planned ascent schedule was overly conservative. And the point is that you weren't in deco to begin with.

What defines whether you are in deco or not, if it's not "what your computer says"?

As I said earlier, at early stages of dive training, deco is taught as a black-and-white, 0-or-1 kind of thing. But, in more advanced training, it starts to become clear that deco is a spectrum. What you decide is "in deco" may be "not in deco" to someone else, based purely on their training, and experience (including their experience with their own body).

"In deco" or "not in deco" really only has meaning in the context of the question "what does my computer say?" Then, the answer is yes or no. if you change your computer settings then the answer may change, but what's going on in your body hasn't changed.

If the question is "am I going to be bent if I go straight to the surface", the answer is never really yes or no. It's more like something like "very unlikely, probably not, maybe, probably so, or almost definitely." Or somewhere in between or on either side of that.

Anyway, regardless of what prompted you, I was responding to:

Hopefully someone reading it will realize how idiotic the notion that, after you're over the "safe" M-values, you can "re-calculate" yourself to be under them again, is. In which case my post was not in vain.

This post implies that selecting a computer that won't lock you out is idiotic. I disagree. You still haven't explained what the "safe" M-values are, versus the "unsafe" ones.

In the original example of the many things you can do to upset a Suunto computer, I can easily imagine some of those to be innocuous enough that a different computer would still get you out with a VERY high degree of safety (i.e. low probability of DCS). It seems to me to very similar to the idea of diving GF30/70, then looking at the computer surfacing gradient and electing to omit the very last portion of prescribed deco, in order to get out with a surfacing gradient less than 80. It may be higher risk, but is the difference meaningful at all? Any more meaningful than ignoring a Suunto that got upset by some very innocuous action and following the non-Suunto that is on your other wrist and is not demanding deco?

Ah ha. I had no idea you were so hip! LOL ;-)

I realize that it takes an extra button click or two, but when you quote someone, sometimes you really should make an effort to quote in context. To wit:

My advice is get a computer that will calculate through your mistake.

While you're at it, get one that will un-bubble your blood and de-gas your spinal fluid after you bend yourself into a pretzel.

That was the statement I later referred to as idiotic. You are of course free to disagree and consider it a fount of sage wisdom instead.

One more thought for you to consider - if you use the divelog software, I much prefer the Pelagic program that comes with the Aqualung line over the Suunto program.

There is an obtuse pattern of speaking on here.
Good luck on a computer. I think enough has been covered to help guide you. Now the conversation has turned into who has a bigger regulator. Someone felt like he got his hose stepped on.

What the what? I can't tell which computer people recommended, just this intense discussion of the thing I try to avoid (deco). I agree both look good. The Aqua Lung is new and so harder to know how it holds up. I still have the taste of rushing into the i750 (God awful battery life and invisible in the sun and shallow water). I have not met a lot of people who were wild about the Eon. Consensus on SB is to get the Shearwater Perdix AI. As long as the Aqua Lung is readable in bright light and it has the 25 hour/ charge battery life, I would suggest you would be happy with either.
Of note, the compass function on the AL i770R is very interesting being able to see it on the main screen if you have a setting to follow. That may make some difference.

Anyone have experience with both the Eon Core and the i770R? Considering getting one and they both look pretty good.

What did you end up getting, and how do you like it?

I use an eon core and love it

So on a computer which insists you do the stops or gets a strop on

Is a safety stop really the best place to be sharpening a knife?
