Air Integrated.
It's a computer that is connected to the tank and tells you its pressure. Some computers can also use this information to estimate remaining bottom time based on actual air consumption, in addition to NDL info. It's a pretty slick feature, and why I own AI computers (Cobra and Vytec).
The connection to the tank can be via a standard HP hose, or via a wireless transmitter that connects to the reg HP port. This allows you to wear the computer on the wrist, or wherever, without having to deal with a hose.
Well, don't keep us in suspense!! Let us know what you buy!!Thanks to everyone for a bunch of highly informative responses! I think I have a great foundation and set of recommendations to make a dive computer purchase.
I could agree more with the diver that suggested the computer is more accurate than a human. We are effected by everything from cold, visibility, depth and how much beer we drank the night before. Computers just don't have those problems.
That's just not true. It is useful. The estimate is for the present depth, based on actual air consumption. This can help you decide when to go up for that 30' reef (and we're assuming NDL is not the limiting factor here). If, for example, your AI computer is telling you that at your current depth, your NDL is 20 minutes, and your air time remaining is 5 minutes, you might want to head for that 30' reef NOW. If all you have is the NDL, then you look at the air remaining in bars (or psi if you refer) and make your best guess for how much longer you can stay at your present depth - based off your "intuition and experience". Your choice. But the computer's estimate is hardly useless - no more so than the NDL it gives - which is also based on a model. At least the air consumption rate is based on YOUR breathing on THAT dive. That's more than we can say for the NDL model.So, the display based on air pressure isn't useful. It isn't your Remaining Dive Time or anywhere close to it.
Yeah....I dunno about that. I bought the Cobra prior to my OW session, after consultation with the dive shop. They probably would have given me some pointers on how to use it if I wanted them to - but a glance through the user manual was all I needed - and I had never used a dive computer (or had even gone diving) before. I will grant you that the menu structure seems to have an odd interface, esp. the log book, but I don't think you did too badly. The thing about the class is that they can hardly give a class for every make and model under the sun. If I were inclined to buy it from a local dive shop, they should know how to use it and be willing to show you at no extra charge. Otherwise, you might as well buy on line and save a lot of money.I wish I had done more research before I jumped in. ALl said it appears I did alright buying the Cobra 2 on advice of my LDS. I have no complaints other than there are more features than I know about. I could have used some more training before I started to use it. As with most technology, the user's manual is inadequate for a first time computer user.
That said, PADI has recently developed a specialty class for dive computers. Putting aside the argument/gripe that this is yet another way for PADI to earn a fee, this class seems like an essential for any new diver. I don't know that I would go so far as to make it a credit toward certs... It's a couple of dollars and a couple of hours of your life in a classroom. I'll give a follow-up on the course...I have the class this Thursday night.
