The computer will “offgas” overnight so there should be no problem, worst case one of you might see mildly shorter no-stop time. Just don’t share it on the same day, that would actually be dangerous.

Try it yourself. Plan few dives, stick in 12 hours surface interval and see that it doesn’t really impact your no-stop time at all, not at these depths.

Same situation when you rent a computer from a dive shop - someone might have used it the day before, doesn’t matter.

If I were you, I would take an SPG too (get one without the funny console and clip it to a D-ring) and the second computer, in case that something breaks. Or at least the second computer as you could rent an SPG.
i dont know for you but when i go dive in belize and honduras i could dive up to 3 even 4 dive a day believe me for a period of 10 consecutive days my mares m1 is taking the hit.
 
If the original plan was to bring both your EON Core and the I330R, one possibility might be for both of you to use both computers on your alternating days. Put the EON in gauge mode so that you maintain the convenience of AI without the risk of its more conservative (especially with repetitive dives over multiple days) RGBM-based algorithm indicating shorter NDL times, and use the I330R with its Buhlmann implementation for the NDL calculations

You really should not compare your Mares to his Suunto. His computer has a conservative, proprietary algorithm that penalizes you for yo-yo profiles, short surface intervals, fast ascents, and using Nitrox, plus maybe other things. Her computer does none of those things, and is fairly aggressive. It would be easy to keep her computer happy and within NDLs but bend his.

i understand that my comment was more in regard to dive likemuppet.

Be safe
 
Your computers are running different algorithm's and the Suunto will be the one that penalizes you the most on consecutive dives and will lock out if you don't keep it happy. If you choose do this, both of you dive both computers and follow the Suunto.

Same with my Garmin Mk2i. It takes a beathing in Roatan. I had a Sunnto and absolutely hated it. My first trip to Roatan, it quit at 75 ft because it wanted me to switch gases. I'm using air, asshat! Why would I switch? Luckily for my wife and I, we had brought our clunky, chunky Scubapro Lunas. At least, they considered our feelings.

It wanted you to switch because the multi gas function was turned on. The computer doesn't quit it's just a notification and if you hit any button it goes away and continues to track your gas loading based on what gas was originally selected. You have to manually switch the gas for it to start calculating based on the new gas selected, turn the function off and problem solved. Suunto gets a bad rap but they are perfectively fine computers I used one for years with no issues and my wife still uses her D9 as a back up.
 
On a personal note, I prefer my gear to be compassionate, considers my feelings and accepts me for who I am. I refuse to dive with a computer that doesn't care.
That's smart. I have had my computer get pissed at me before, sometimes in the presence of my friends. It can be embarrassing for me and inconvenient for everyone.

It is not a good situation, sometimes it takes an extended period of time to cool her off and this can be a boring and tedious task, waiting for that b!tch to make up her mind and forgive me for past transgressions. My buddies will sit and complain through the whole ordeal and when I return, they can't seem to comprehend why "I can't just treat her right"?

However, sometimes she becomes completely irrational; I generally make a feeble attempt at appeasement and when that proves to be futile, I just blow her off completely and lock her in the garage for the night. She seems to have a better attitude after a night outdoors.

That's one advantage of Shearwaters;you never have to lock them in the garage overnight.
 
lol she was acting up today. Never seen this before, started complaining about oxygen levels! She threw such a hissy fit, just gave me zero time at all depths on the bottom and during ascent and provided no information on nitrogen! 3 days of hard diving did not sit well with her apparently.

She’s getting a cold bath and gonna stay in the garage for the rest of the weekend.
