I have an Oceanic VT3 (complete with transmitter and receiver) that have never seen the water. I bought an extra one on accident (I thought I lost my other one, but found the previous one before I used the new one) and would like to get this out to someone who will use it. I paid almost $1,000 for it but it has been a few years with it in the box. It will probably need new batteries due to shelf life. Not sure what it is worth so will consider all reasonable offers. Would like to sell quickly. From my understanding from Oceanic, the new version, the VT4 does not have buddy check. The VT3 does and it is a great computer.
