Doug,
I've a question I hope you can answer. I currently have a DataTrans Plus with the wireless transmitter and a DataMax Sport with an expired battery, the latter no longer replaceable but an upgrade to the Veo 180 being offered at a good price. Rather than do that, I'm more interested in seeing if I might get any discount on a newer wireless computer, most likely the VT Pro or VT3 (preferably). I've always kept the DataMax Sport in my BCD pocket as a backup on dives and that would be the new place for my DataTrans if I bought a new computer. But, I wondered if I'd have the advantage of still having wireless tank pressure monitoring. This led me to questioning whether one transmitter would work effectively with two computers, and I verified today at ScubaToys that indeed, a current Wireless Transmitter is backward compatible to the DataTrans Plus, as it and the Aeris Elite used at the store were reporting the tank pressure accurately. Sweet!
As I drove home, I realized I should have taken in my tranmitter to test for forward compatiblity. That is, would current wireless Oceanic/Aeris computers work with my 8-year old transmitter without a problem? It seems they should since tank pressure is the only data transmitted and I'd expect similar encoding to be used. But, if any changes have been made to help prevent signal loss, provide faster sampling of tank pressures, etc. then I could see where forward compatibility may be less likely found than backward. If I were to buy a complete computer/transmitter set, then at least I know my old transmitter would provide me an ability to make use of the VT3's Buddy Check feature if ever there was a reason, or simply provide a spare in the event of a failure while on a trip. But, if the new transmitters are no different from the old ones, the added cost of a tranmitter would sure be a nice savings at a time when I'm making some serious investments into u/w photo gear. Of course, I may even decide to forego any new computer purchase at all since the DataTrans Plus works great and only has the drawback of being bulkier than newer models; I even realized it presents more info...the ascent rate and air consumption rate graphics which are useful to someone who tends to suck a tank dry pretty easily when toting a camera rig.
I appreciate your feedback on this.
