Buddy Watcher seems like an idea that would only work if you and a friend dived alone.Does anybody know exactly what killed Liquivision computers and the Buddy Watcher pingers? I'm sure someone will get this ultrasonic thing right eventually and I hope it's the Oceans guys, but you gotta wonder why the previous takers failed.
In a group dive I am pretty sure the other people would be pretty pissed off if they kept hearing high pitched sounds coming from you and your buddy. Plus it's $250 for what is really a fancy tank banger, that's a lot of money for an underwater whistle.
Liquievision looks like a Beta product, it just looks like it was never ready for prime time.
Maybe some other company bought out the software and integrated it into another DC.
