Recent reviews thoughts on Liquivision Lynx U2?

[Diving Dubai]

Hi Erik

Good post, and very informative. You have no idea how much I desired the Lynx - when I desire something badly I'll even overlook the bad points but there was always something niggling at the back of my head about the Lynx. I also thought long and hard about the Petrel but in fairness I wouldn't use a lot of its functionality and my wife (who shall be obeyed really wanted AI

I dislike the algorithm on the suuntos as well, and have seen people get significantly shorter bottom time after repetitive dives.l)

I'm no experts on Algorithms however from actual experience I've never found the Eon to limit my NDL. Indeed on a recent trip on the deep dives to 30m we had more NDL than people on other computers (the Atomic springs to mind. If memory serves (without checking my logs) at 30m I had about 35mins on 32%. My old Cressi Leonardo was hugely more conservative. That said I feel that Suunto's advertising of the Eon being for serious Tech diving is a bit far fetched.

Everything that locks you out has nothing to do with Tech computers.

It's not so much noticeable on the first dive with the eon, but have you compared what happens to your allowable bottom time after 2 or 3 dives compared to others? Not much of an issue if you don't do much repetitive diving per day, but I was on a trip in Aruba, and 2 guys had suuntos and we had to really drag out the surface interval to get their computers to give them the bottom time we were planning. I don't remember specifics, but it was something like they were showing 5 minutes allowable bottom time while I was figuring around 30 depth planned was around 50-60, and we ended up waiting 30 minutes to get them to 20 minutes and the both entered deco and were much shallower a large portion of the dive. This was after multiple days of 2/3 dives a day. The first dive profile and Ndl was very similar, but after that, it got extremely conservative, extremely quickly.

im very happy with the Lynx and don't regret it at all, of course stick with the wifey on your decesions and her desires, have you looked into the mares hd at all? I have some friends who use them for recreational diving, might be another option you want to consider. I went with the Lynx over the mares for the tech aspect, but one annoying thing about the Lynx transmitter, is it like audibly clicks or makes a cracking sound when it emits its signal, which I found annoying at first.

Oh oh for heavens sake. The only way it will lock you out is if you bust your deco ceiling by 3 minutes. In extreme circumstances in tec diving I understand this may be an issue. In normal rec diving if you can't maintain your deco obligation you shouldn't be getting into deco. 150 dives no issues!

my example was day 4 so dive 10 on a Liveaboard. Got around 150 dives on the Eon so far and no real issues. There have been a couple of slight problems but that was the human interface not the unit. I have reported some minor functionality changes I would like to see - but they're down to personal preferences.

Glad you love your Lynx. The real issue was living where I do I would have to import the batteries, and no in country dealer so if something did go wrong it would need to be sent back. On of the other major factors was wanting something my LDS could support as I dive most weeks. Interesting note on the TX noise. Hadn't thought of that.

dis look at the Mares, or I should say I tried to look. The LDS at the time (now gone) wouldn't even sell me it, he knew the type of diving I did and couldn't recommend it to me, even though he knew I'd buy 2 then and there. Can't fault his honesty for losing a sale, but I've never had one in my hand so can't comment

actually the wife didn't really have that much say in it. But I will say one thing, she hates reading manuals but picked up The Eon very easily.


i also think different computer brands are favoured in different countries. For instance 5 others have them here, I went on 2 separate liveaboard, one to the Red Sea and One in the Phillipines this year. On both boats there were as least one or two others with Eon's - yet I only know (and have seen one other petrel. I'm not saying that is an indication of anything other than territory mRketing and sales perhaps.

horses for courses and all that

i hate lockouts, I've had my dg03 go out of gauge mode into normal, and i set it to gauge (besides that being how i dive tec) because i don't program my deco gasses in, so on my ascent, it told me i had some 50+ minutes of extra deco time (assuming air only) so i blew it off and followed my cut tables using my petrel and the correct gas switch, but it becomes undiveable for 24 hours, which to me is a problem. i also hated that i had to set it to gauge mode then immediately descend or it would revert to dive mode. that to me was one of the reason i bought the lynx for gauge, expensive bottom timer, but so easy to read.

i wasn't going to deal with the battery issue, so i paid for the rechargeable ones, i much prefer the way shearwater does it with the AA's on my petrel, you can get them anywhere in a pinch.

im glad you are enjoying the eon and aren't having the same algorithm conservatism I've seen displayed by them

When I was looking this was the top of my list. However a Lynx owner PM'd me letting me know about the battery tray. Also because the batteries are very specialised getting replacements looked to be a PITA. Even the rechargeable batteries needed new O rings so I'd have needed a whole bunch. In the end the disadvantages for me far out weight the advantages and I went with the EON - which is universally hated on SB because it has AI cost the same as a Lynx and is not made by Shearwater

Ding ding round 3, you are correct in that the Eon is not often recommended here on SB but not because of the reasons you state. Hate is such a strong word, dislike immensely is more accurate Just playing

On two occasions I have been asked, — "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

If I wrote the software for that thing, it'd go into gameover mode instead of a 24-hour lockout. Reverting from gauge to dive is definitely a problem worth taking to tech. support. And if you never tell them, they'll never fix it.

Ding ding round 3,

I haven't heard that phrase in years My Father used to use it

It made me smile this morning as it brought back happy memories from times past. Thank you

I'll weigh in here, especially as I'm quoted earlier in the thread.

I had a lot of issues in both the T1 transmitter and Lynx computer with the rechargeable batteries sold by Liquivision.
Liquivision first replaced my T1 with a U2 - I still had battery issues.
Then Liquivision tried to service the wrist computer (at great shipping expense to my local LDS) - no improvement.
Then Liquivision replaced my Lynx wrist computer and all batteries and even the charger unit.

I just got back from a 32 dive trip and can report that you can get approximately 15hrs from the blue disposable batteries and maybe 4 hrs from the rechargeable.

Things to note:
- You MUST correctly designate the type of battery used in both the wrist computer and the transmitter.
- At the end of each dive, it is imperative to immediately close your tank and purge all pressure from the 1st stage - otherwise the transmitter will stay on. I managed to get only ONE dive out of a freshly charged battery when I did not do this.

I'm a photographer and am used to a daily schedule of camera & strobe battery switching and maintenance. I've added the Lynx and transmitter to this routine.
It adds the need of a second set of rechargeable batteries, and the need for o-ring care.

The benefit is an exceptionally easy to use (tapping gets ridiculed by other divers, but it is very simple to do) and extremely easy to read computer.

(NB: All dives done in tropical waters, with no deco/ mixed gas/ etc.)
