| | | All vital information displayed on a powerful echosounder | | |
| | | |
| | | Main echosounder screen, showing trawl lines starting where the trawl is. This information is either taken from the depth sensor or the height sensor. The built in trawl calculator calculates the distance to the trawl based on the ships speed and wire length. The trawl height on the screen is 4.1m off the bottom. The bottom expansion function is a vital tool to distinguish fish from the bottom. Here the white line is turned on to even easier separate fish and bottom. The trawl line will also be displayed in the bottom expansion display giving a better resolution. | | |

| | | Hydrophones The hydrophone is mounted in the hull facing the net. For Purse seine one hydrophone is installed pointing at the purse seine. For trawl it is recommended to install two hydrophones facing the trawl. This will ensure constant communication during turning and if the trawl is off centre line. A portable hydrophone is also available for trials and as intermediate solution while waiting to haul the vessel. | | |
| | | High performance transducers Installing the highly acclaimed Simrad transducers will give you maximum performance from the echo-sounder. The Combi-C and D transducers come in 38/200kHz and 50/200kHz and is the perfect match for the PI44/54. | | |

| | | Active PI Charger The PI Charger enables intelligent and safe charging of all sensors. | | |
| | | Automatic hydrophone selector A trawl is often not in a straight line behind the vessel, it is on one of the sides. The automatic hydrophone selector switch selects the hydrophone that has the best signal level and makes sure that you have optimum reception at all time. The switch can be set to manual if necessary. | | |

| | | The new sensor family The PI family is continuously growing. The new cable based FS70 system can be integrated with the PI system. All information from the PI system can be displayed on the FS giving pelagic trawlers better control of their trawl and a perfect back-up if the third wire breaks. | | |
