1.4 Catch Sensor CS-400 (option)
Mounted on the cod end of the trawl, the catch sensor monitors the catch of fish.
Four catch sensors may be mounted. The data from each catch sensor is
transmitted to the underwater unit via the acoustical link and sent to the
Processor. Tx frequency for each sensor is selectable with an internal jumper
block.
The catch sensor is powered by three “D” alkaline batteries. If they have
not been installed, see page 44 for how to install them.
Note:
If the unit will not be used for a long period of time, remove the batteries.
