The PACS, Portable Acoustic Command System, is a highly versatile deck unit that can be used to control and range on EdgeTech’s (formerly ORE Offshore) low frequency (LF) or medium frequency (MF) acoustic releases and transponders.  The rugged, lightweight unit provides a highly intuitive user interface that allows you to go right to work, spending your valuable time in the field, not in training. The system is powered by internal, readily available off-the-shelf alkaline batteries. The PACS works with all standard EdgeTech acoustic transponding releases.
