IThe clanger? I got off the plane when it landed and headed straight to the LDS where I bought it and said it had to go back. It continuously lost the transmitter signal, even though the battery said "high". (There's another thread on this board from others who have had the same experience). Sometimes I didn't hear the beeping right away through my hood. And at some point, after the signal has been lost long enough, it ceases to calculate remaining bottom time as per air consumption. That's not a complete show stopper as I generally know when I need to start to ascend based on remaining pressure but when you pay this much for a computer, all the bells and whistles need to work. And its a PITA to constantly be trying to reconnect the signal. In a 90 minute dive, I'd probably lose it 20 or 30 times. I tried rotating the thing 180 degrees (which you can do, and which felt better on my small wrist, actually, having the weight at the bottom rather than the top), but that seemed to make the signal loss worse. Once at the LDS, the owner said that he'd never heard of this happening in any of these computers he'd sold. He phoned the rep immediately who asked a couple of basic questions - did I wear the computer on the same side as the transmitter (yes). (It wasn't pointing at my head as my regulator - an Oceanic Delta 4 FDX 10 - just doesn't allow for that.) Was the battery good (yes, brand new). So off it went. So we'll see.
The manual says that flash photography can affect the transmission. I was the only person using a camera in the group throughout my dives, and it still lost the signals even if I didn't have the strobe turned on.
I hope they will be able to get it working properly because it's a pretty cool computer. Otherwise, I will not be keeping it, obviously.
Finally heard back from LDS that Uwatec has shipped me a brand-new replacement computer. Hooray!
