| | | |
| | | The Bottom contact sensor monitors if the ground gear is on or off the bottom. Increase your efficiency; stay in touch with the bottom. Do not tow with heavy bottom gear; trim it till you have the perfect balance. | | |
| | | |
| | | Bottom contact is indicated on screen and with an audio alarm. The net has been off the bottom for 7 minutes. Bottom trawl | | |
| | | |
| | | Bottom contact sensor on a bottom trawl gives you fast update and accurate information. Adjust the length of the sensing chain to see when the ground gear lifts a few cm off the bottom. Bottom contact sensor on a purse seine gives an alarm when the sensing weight touches the bottom. This enables you to fish close to a rough bottom. Bottom contact sensor on a pelagic trawl. Adjust the length of the sensing chain to avoid towing on the bottom and tearing the net. | | |

| | | The Simrad PI Catch Monitoring system receives information from up to six sensors at the same time. The system uses a hull mounted- or over the side hydrophone. The net's depth, water temperature and the important bottom contact information are displayed in large digits or easy to understand graphics. The Simrad PI system is designed with different codes to avoid | | interference between vessels operating close together. The small size, quick update rate, long battery life and its long-range capability, allows the PI system to be installed on any size net, from a small sardine net to a large tuna net. The PI system interfaces to the latest professional Simrad echosounders and sonars. | | |
