That's surprising. My Uwatec Air-Z Nitrox has been back to Scubapro twice and both times it was free. The first time they replaced the transmitter with a new one. The second time, it died on a dive on me and they replaced the batteries in both the transmitter and wrist unit for free. This was just last year. My local dealer sent it back for me with others he was sending in and Scubapro never charged a thing. He didn't even take my info (just my name and phone #) so I know they didn't match it up to me. This is also not the dealer where I purchased the unit. I purchased the unit in Bonaire several years ago. When I tried to return the unit myself to Scubapro, they told me that they don't accept units for service from individuals and directed me to my local dealer. Perhaps you could have a local dealer send it in using the original owners name?
