I have a pretty much brand new Oceanic Datamask and Transmitter I'm looking to sell. It's pretty much brand new. I have only had 2 dives with it and the deepest I made it was about 20'. It works perfectly fine. I just don't dive anymore so I'm looking to offload all my gear. Have some other stuff aswell. I'm not even sure if there is interest in this mask since it's been discontinued? Let me know if your interested. Thanks
