NOTE: Settingsaredependent onthedepth capabilityof yourparticular Fishing System model.
For example, if you are fishing in 60 feet of water but are only interested in
the first 30 feet (surface to a depth of 30 feet) you should set the Lower
Depth Range limit to 30. The display will show the 0 to 30 foot range,
allowing you to see a more detailed view than you would see if the display
went all the way to the bottom.
