I just wanted to give any Uwatek Smartcom owners out there a heads up about a problem with some of the units. Last week my LDS called me and told me he had heard from another area LDS of several instances where an air leak developed at the quick connect/disconnect. Sure enough, on my second dive on Sunday it started bubbling.I have about 15 dives on this computer so it took a while for the problem to manifest itself. Supposedly it has something to do with faulty o-rings and a special tool is required to get at it.I'm just glad I was on a day trip and this didn't happen on one of the three day spearfishing trips I do 90 miles out in the Gulf of Mexico.If you have this computer I would suggest you talk to your LDS before you get a screwed up trip like me.Unfortunately, the LDS might not be aware of the problem because at the time I talked to my LDS ScubaPro had not issued any info about this to their dealers.
