Sonar Setting the Fish Alarm You can set an alarm to sound when the chartplotter detects a suspended target of the specified symbols. 1. From the Home screen, select Configure > Alarms > Sonar > Fish. 2. Complete an action: • Select to sound an alarm for all fish sizes. • Select to sound an alarm for medium and large fish only. • Select to sound an alarm for large fish only. Transducer Configuration Setting the Keel Offset The keel offset compensates for the surface reading for the depth of a keel, making it possible to measure depth from the bottom of the keel instead of from the transducer location. Enter a positive number to offset for a keel. You can enter a negative number to compensate for a large vessel that may draw several feet of water. 1. Complete an action, based on the location of the transducer: • If the transducer is installed at the water line, measure the distance from the transducer location to the keel of the boat. Enter this value in step 3 as a positive number. • If the transducer is installed at the bottom of the keel, measure the distance from the transducer to the water line. Enter this value in step 3 as a negative number. Transducer at the water line A (+) positive number shows depth at the bottom of the keel. Transducer at the bottom of the keel A (-) negative number shows depth at the surface. Keel Offset 2. From the Home screen, select Configure > My Boat > Keel Offset. 3. Complete an action: • For the GPSMAP 6000 series, use the Rocker or the Numeric Keypad to enter the distance measured in step 1. Ensure that you enter a positive or a negative number based on the location of the transducer. • For the GPSMAP 7000 series, use the on-screen keyboard to enter the distance measured in step 1. Ensure that you enter a positive or a negative number based on the location of the transducer. 4. Select Done. 106 GPSMAP® 6000/7000 Series Owner's Manual
