Components - Trawlmaster for Twin Rigs
Command Unit
The command unit is the acoustic receiver that is the “brains” of the operation. It is powered by 120/240 VAC. The command unit connects to a computer and to the hydrophone.
Hydrophone
The hydrophone sends and receives wireless signal to the sensors. There are three types of hydrophones:
Omnidirectional Hydrophone
360° beam and for ranges of 700m and less
Long Range Focus Hydrophone
70° beam and for ranges 700m to 2000m
Portable Hydrophone
this hydrophone can be hung over the side or slid down the trawl wire.
Battery Chargers
The Fast Charger can charge sensors in approximately one hour and will indicate when the batteries are charged. Different models are available to charge one, two and four sensors simultaneously.
Fast Charger (charges one sensor)
Fast Charger (charges two sensors)
Fast Charger (charges four sensors)
