No major problems with the unit. The one minor problem he has had is the same one that I've heard others mention. It occasionally loses the signal from the transmitter. A move of the arm to put the computer close to the transmitter restores the signal with no loss of dive data. The deepest he has had it to date is 50 ffw. YMMV Do you need to track more than one travel gas? Deco gas? That said, I didn't care for the smaller face/dial read out. But I haven't seen much of an improvement in regards to that feature on any of the newer 'puters. Good luck with the permutations.

Magnitude of order more reliable. >> Just use a J valve - much simpler. > Magnitude of order more reliable. You meant less reliable, right ? 8^) The biggest problem with the J valve always was the failure of the user to open it when filling a tank and closing it before using it. Say what you will about dive computers, in the overall scheme of things they're a lot more reliable than the recreational divers that use them. Mine, for example, have never failed to reset to 78% nitrogen and 50% oxygen about 10 minutes after a nitrox dive. I, on the other hand, have failed to reset them to what I'm actually using several times. You want something like this that's really reliable, buy a regulator with an unbalanced first stage. It will get noticeably harder to breathe at approximately the same pressure that a J valve holds in reserve. If you want more margin, go with both the unbalanced regulator and J valve. A combination of distraction and narcosis, can make it possible, if not easy, to fail to notice how hard breathing has become, but we're not talking about a technical rig anyway.

Yeah, or the Dive Rite computer that resets all the gases to air at midnight, even in the middle of a dive. It is not at all uncommon for us to be cave diving at midnight. You have to remember to set its clock so it doesn't go through midnight during your dive. > Yeah, or the Dive Rite computer that resets all the gases to air at > midnight, even in the middle of a dive.

I think mine may be one of them. > Cindy's Nitek3 does it; I don't know about any of the others. My Nitek He does something related to gas at midnight. I'm just not sure what conditions affect whether it does it or not. I'll look at the manual and let you know. Lee >> Uh Oh. I think mine may be one of them. > Cindy's Nitek3 does it; I don't know about any of the others. Here's what the manual for the Nitek He says: Once the computer's gas mixes are programmed, the settings are stored in the computer until midnight unless the computer is underwater. Here's what the manual for the Nitek Duo says: If you set either mix for Nitrox or oxygen (FO2s of 22 to 99 percent), the computer assumes that subsequent dives will be made on Nitrox. Thus, to protect you from accidentally diving a Nitrox mixture that cannot accurately be monitored, the computer's FO2 setting defaults at midnight (it does not default at midnight if you are under water). Unfortunately, here's what the manual for the Nitek 3 says: If you set a Nitrox mixture, but do not dive with the computer, the NiTek3 holds the programmed gas mixture until midnight, then defaults. The computer does not default at midnight if you are diving. If you are sure that Cindy's computer resets everything at midnight, you probably should contact Dive Rite to discuss the problem. What you are reporting is contrary to what the manual says will happen. Lee > If you are sure that Cindy's computer resets everything at midnight, you > probably should contact Dive Rite to discuss the problem. What you are > reporting is contrary to what the manual says will happen. It is a well known and documented defect. Every Nitek3 does this, or at least the older ones do. It's a very popular computer in cave country, and those guys know all about it. > It is a well known and documented defect. Every Nitek3 does this, or at > least the older ones do.

This is so simple to test that, if I'd known about the issue before last weekend, I would have done it already. Before my next dive, most of which I so using the Oceanic computer in its console, I'll set the He to something other than air and the time to a few minutes before midnight.

I 'm sure it has been fixed by now. The firmware went through several changes over the life of the product, so it was probably one version that did this. I looked around tht internet for more information, and didn't immediately find as much as I though I would. It makes me wonder a bit about the big deal the cave diving community made of this a few years ago. > It makes me wonder a bit about the big deal the cave diving community made > of this a few years ago. The hard core among cave divers tend to make a bit deal out of any computer issues. I have to say, though, were I to be diving deep and long, with the kind of decompression obligations that includes, I'd be more than a little annoyed if my computer reset everything to air, or anything else, at midnight. If Cindy's computer still does this, I'd still contact Dive Rite to see what they are willing to do about it.

Well, I can scratch that off the list. Exactly. If you have to wait until after a midnight dive to start drinking, you never sober up enough for the morning dive. I try to stop my diving by 8 p.m. so I can finish my drinking by midnight and be up for diving by 8 a.m. It's the 12-hour rule. >>>Yeah, or the Dive Rite computer that resets all the gases to air at >>>midnight, even in the middle of a dive.

Well, I can scratch that off the list. First, it might be a good idea to determine if the reported problem is common to all similar units or a problem only with Cindy's. The manual for the Nitek 3 clearly states that it does not reset if you are diving. The manual for the He and Duo, both clearly state that the computer does not reset at midnight if you are under water. One has to wonder why they use different language for the three computers. Second, I think it might be good to determine that what you think Al said is what Al actually meant to say. Finally, it might be a good idea to decide whether you really care what happens at midnight.

As a software developer, I have to wonder exactly *what* they were inhaling when they wrote that code... That even more braindead than the way they had some of the UNIX workstations setup back when I was working for NASA (actually a NASA subcontractor)... They had them to automatically reboot at 02:00... Unfortunately, we were quite often still there working at that time and would end up losing work because we hadn't saved the file within the last few minutes... > As a software developer, I have to wonder exactly *what* they were > inhaling when they wrote that code...

Ummm, let's see here. You're a software developer. You knew that the computers rebooted at 2:00 AM, but you lost data because you hadn't saved the file, and you think they're brain-dead? Check. 8^) Lee >> As a software developer, I have to wonder exactly *what* they were >> inhaling when they wrote that code...

It went down for the count, would not boot up. Called Oceanic, they gave me a return auth. number. Sent it back Aug 8th and asked if I could get it back by Aug. 23rd for a dive trip. Brand new replacement arrived the 22nd, with hand written note on shipping order "expedite shipping, customer needs by 8-23. Not bad for a big company. I will keep that in mind when I replace one my others. Regards, Dan > One of the three computers I have is an Oceanic Pro Plus 2. > (for Lee--other two are not air integrated ;). [quoted text clipped - 3 lines] > 22nd, with hand written note on shipping order "expedite shipping, > customer needs by 8-23. Not bad for a big company. There's a pattern here. I had a problem with my wife's Oceanic air integrated something or other too. I sent it back through a shop with instructions that it had to be back for our vacation in a couple of weeks. They called it in and confirmed that it would be back in time. Sometime around the middle of the second week, I called to see what was going on. Oceanic overnighted a new, and better, air integrated computer the same day. I like their non air integrated computers (because I don't like air integrated from anyone) and I like the way their customer service people responde to problems. > I will keep that in mind when I replace one my others. Word of mouth advertising, pro or con, is hard to beat. Lee > Ummm, let's see here. You're a software developer. You knew that the > computers rebooted at 2:00 AM, but you lost data because you hadn't saved > the file, and you think they're brain-dead? Well, the first couple of times, we just thought it was a hickup... Considering the fact that it was that late, our caffeine level was probably a bit lacking... Eventually, I noticed that it seemed to happen around the same time, so I did a bit of investigating on the system and discovered that it was set to automatically reboot at 02:00... When we were onsite, the machines over there were not setup that way... Often, we were onsite at 02:00 and some days, we didn't end up working all the way to 02:00... As such, it took a few times for it to occur before the pattern was noticed... >> Yeah, or the Dive Rite computer that resets all the gases to air at >> midnight, even in the middle of a dive. It is not at all uncommon for [quoted text clipped - 8 lines] >still there working at that time and would end up losing work because >we hadn't saved the file within the last few minutes... Better yet, both VAXen and Auspex had an interesting problem. Their TOD clock was only 64 bits and would reset every (roughly) 412 days. So, mission critical or not, they had to be rebooted once a year to avoid this "little problem". And it wasn't documented anywhere.

And it wasn't documented anywhere. Hmmm... Sounds like a "problem" that we had with an AIX box a few years back... Don't remember the exact scenairo, but it basically needed to be rebooted every 3.5 or so years, whether it needed it or not... Too bad our Windows servers couldn't be that reliable... Hell, we felt good if they could go a day without needing to be rebooted... We found it hard to believe that companies actually used Windows for mission critical systems... >The biggest problem with the J valve always was the failure of the user to >open it when filling a tank and closing it before using it. And the other failure mode waiting for you even if you did everything right. My buddy ran out of air on one dive because the pull rod got knocked on something and the J valeve was thus set to the "use the reserve" position.

I sometimes use steel-72s in a sidemount configuration and having the J-valves right there basically in front of your face, you don't have that problem... |
