no not new done a small amount of dives no marks all in excellent condition up to date software, so bargain?
Around £150 off new (or more depending where you shop) so yes, a pretty good deal. Earlier Petrels can be had for less but then they are older and are missing some features
I have an eon core, which works as a wonderful bottom timer.
If only they had proper algorithms where you could choose your dive planner....
If only they had an algorithm that wasn't broken...
Does the EON have a screwed up MOD calculation too? e.g. 28% = 40m in normal terms, but 38.3m in made up Suunto terms
dose / mix = MOD (actually pressure in bar or ATA)
1.4 / 0.28 = 5 = 40m
Apparently the discrepancy is some "added conservatism" which they've pulled out of their jacksies.
My mate, on his OSTC, was diving with a buddy on trimix. They got to 21m, gas switched and the buddy's Eon didn't want a stop. They did at least 3 minutes at 21m, went up to 18m and the Eon wanted 2 mins. Its ceiling calculations are weird.
I've heard many things, but the one I believe is that it rounds the percentage mix and depth both up and down respectively to form a worse case scenario and gives the MOD based on that. Apparently I can't analyse gas accurately or stay within the MOD without the added help of a computer...
Personally, my level of conservatism is using a max ppo2 of 1.3 instead of 1.4 - which is a conservative maximum in itself anyway.
I don't, and never will trust the suunto, it's fine for no stop stuff but past that I'm backing myself up with proper deco planning before hand anyway. I'm not lying when I tell you the thing spends at least 70% of its time in gauge mode...
Was looking at the Suunto Eon core and steel comps from comments here glad I did not buy one. I managed to get an Oceanic VTX with just the 2 test dives but ex-display for a really great price and hopefully will be a good backup when I eventually upgrade in a year or two.
