O yes, and i think i'll need some transparent meshes for standard ubt hydrophones after all... they are destroyable but i have very strange behavior when 0HP is reached (game freeze most of the time ). Also note , that after hydrophone is destroyed, it is unusable but only for player, AI can give you bearing even after...Bummer...
P.S. Do you guys from subsim use any form of voice comunication, teamspeek, skype or something? My typing takes so much precious time for modding...
