Sonar Setting the Water Temperature Offset You must have a water-temperature sensor or a temperature-capable transducer. The temperature offset compensates for the temperature reading from a temperature sensor. 1. Measure the water temperature using the temperature sensor or temperature-capable transducer that is connected to the chartplotter. 2. Measure the water temperature using a different temperature sensor or thermometer that is known to be accurate. 3. Subtract the water temperature measured in step 1 from the water temperature measured in step 2. This is the temperature offset. Enter this value in step 5 as a positive number if the sensor connected to the chartplotter measures the water temperature as being colder than it actually is. Enter this value in step 5 as a negative number if the sensor connected to the chartplotter measures the water temperature as being warmer than it actually is. 4. From the Home screen, select Configure > My Boat > Temp Offset. 5. Enter the temperature offset calculated in step 3: • For the GPSMAP 6000 series, use the Rocker or the Numeric Keypad to enter the temperature offset. • For the GPSMAP 7000 series, use the on-screen keyboard to enter the temperature offset. 6. Select Done. GPSMAP® 6000/7000 Series Owner's Manual 107
