| | | The perfect back up By installing a PI cabinet and hydrophone, you have a complete back up system for catch indicators and other sensors. It is now possible to get trawl height, door spread, catch and depth information from the wireless sensors by implementing the receiver from the wireless PI system into the third wire FS system. In addition all the data from the wireless sensors can be received wireless by the vessel making it the ultimate back up system if the third wire breaks. | | |
