The Aladin Pro Ultra dive computer. $526.40. If this Ferret was brave enough to go diving – among all those creepy crawlies and slimy things – then this is definitely the watch he’d wear. Not the gold Rolex, oh no.
The Aladin Pro Ultra has an oxygen clock that keeps an eye on O2 toxicity. This computer also allows you to dive on normal air at 21% O2, or dive on a level of O2 from 22% to 50%. And as a PC is not required to change the O2 mixture, you can dive on different mixtures during the day. Your bottom times are simply recalculated whenever you change the Nitrox mixture. The Aladin Pro Ultra computer allows the maximum operating partial pressure of O2 to be programmed by a PC.
May I suggest instead the Aladin Air 2 O2 (http://www.uwatec.com/imperial/framem03.htm) which sports also a wireless transmitter that mounts to your tanks to give you *actual* mixture as well as remaining pressure. Very nice for knowing for sure what you’re breathing and how much you’ve got less.
Of course, that’s also saying you trust a wireless transmitter at 200ft. Wireless *never* goes out, eh? ;) that’s why analog hoses are a good backup. (and why I use the Suunto Cobra)
Er..Andrew, did I mention a fear of dark, damp depths anywhere? :-) Wireless, cabled, tethered or tweaked. It’s all scary stuff to me. I get a fright just watching Titanic footage on TV. :-)
