I know, by now a very old fossil

but I was wondering whether it would be possible to have one sonar gear (the WCA) to be working on the surface and the JP start to work at shallow depth.
Does the game switch sonar gear completely (JP instead of WCA) or does it add them? I just installed S3D Editor and would like to change some things in TMO 2.2 (SD Radar spoils the fun of hoping to evade a plane flying low - not talking historical correctness here

).
