I must admit that I have an ever decreasing regard for Scubapro.
I originally had a 2nd hand Aladin Sport. Bullet proof. Only had to change battery (going on future dealings, I am in doubt if this was required) and rescue it in the surf when it unclipped while getting into a semi rigid (still unable to manually unclip!).
I gave it as a present to the DM at the resort I go to annually. Since then, she has used it on every dive extensively. It still has battery and works without a hitch.
Then I got a Smart Z. Worked fine until it refused to pair a few years later. Sent to the agents. They replaced the battery of the unit (still had aroung 70%) and sold me a new sender.
From then on, I had to re synch virtually each dive session until about 6 months later it would not pair.
The at the end of Sept 2018, it packed up completely.
I returned it to the agents, who informed me that the battery terminal had broken. The only explanation was I probably dropped it. It needs to be noted that the agents were the only ones to work on it (the previous year when doing the unnecessay battery change). Then they blithely told me they had informed me at that change that the terminal was dicey. In what life?
They told me the battery of the new sender unit was flat??? But the wrinkle was that it was not the one sold to me!
I thought maybe a swop had occurred at one of the dive sites until reveiw of my dive logs showed that I had not dived outside my Club scene, so the unit was never out of my possession. I have checked the sender units at the club, but all match.
In the end I had to settle for a Luna, which was rather expensive and an overkill to my needs.
To add to my distaste for Scubapro dealings, I was unable to get replacement parts for a 2nd stage. (Diaphragm and faceplate that had been damaged.) I was supposed to send the whole unit to them to fix. Need professional trained technician to remove the old and replace. Purlease.
Luckily I found compatible parts elsewhere. (It is amazing how many of the basic parts of older models are sourced from the same manufacturer.)
