I have for sale a like new Uwatec Smart Z computer. It has all the manuals and hard case and comes with the transmitter and the Irc thing that hooks up to a USB port and software. It had 17 dives when I got it and I put on like 6. I am asking 550.00 for everything shipped in the states only USPS OR may consider a trade for a wrist puck like a vytec viper something along those lines. I just dont like it ... maybe a bit much for me even though its big , I can't see it it it well, but can see my Geecko fine ... go figure. I'll check here and PM. Battery life is at 97%
