Viewing the Temperature
Use the Temperature sub tab to view a graph of water temperature
changes over a period of time. The graph reads from right to left
so that the most recent temperature measured appears on the far
right side of the graph. The dotted lines within the graph indicate
intervals in the temperature scale and the duration of time. To view
temperature information, you must select Temp (or Temp, Spd.) as
the transducer type on the Setup sub tab.
NOTE: You must be receiving proper sonar data to view
temperature information.
To access the Temperature sub tab:
1. On the Main menu, highlight the Sonar tab.
2. Select the Temperature sub tab.
