Simrad PI44/PI54 Catch monitoring system
The Simrad PI44 and Simrad PI54 Catch Monitoring Systems are both an integration of proven commercial fishing technologies which can dramatically increase the yield and effectiveness of purse seining, danish seining, bottom trawling and pelagic trawling applications.
By means of six underwater sensors mounted on the gear, this robust, maintenance-free catch monitoring system allows unparalleled control over fishing operations by providing continuous, centralised information on the vessel’s position, its gear and the environment at and below the surface.
The Simrad PI44 and Simrad PI54 Catch monitoring systems each consists of an operator station, a hydrophone and an optional echo sounder transducer. The hydrophone and the transducer are both mounted under the vessel’s hull. The system further comprises a number of small and robust sensors measuring the conditions on your fishing gear.
The sensors are powered by built-in rechargeable batteries. They are housed in titanium casings, and designed using advanced shock absorbing materials. The information collected by the sensors are sent through the water to the hydrophone by means of coded sound waves. From the hydrophone, the signals are sent to the operator unit, which decodes the information, interprets it, and finally present it to you.
(A) Operator Unit
(B) PI charger
(C) Hydrophone (provides communication with the sensors)
(D) Optional echo sounder transducer. Several types are available.
(E) Sensors mounted on the net. Maximum six sensors may be used simultanously, and several types are available.
(F) Interfaces to external sensors (serial lines, NMEA format)
(G) +24 Vdc power
The difference between the PI44 and the PI54 is only the physical size of the display.
