I have an Oceanic Datamask for sale. It is about 1-1/2yrs old. It has about 30 pool dives, 4-8 fresh water & 4 salt water dives on it. The mask is in good shape. Both mask & transmitter batteries were changed about 6 mos ago. It is just not very practical for the type of diving I do. It will come with the mask, transmitter, extra mask battery hatch & O-ring, download cord & software. Asking $900 + S&H. I can be PM'd here or e-mail to tstormwarning@yahoo.com for further inquiries & information.
