Greg brings up a good point here that may need to be noted...

The "Max Depth" setting (under the Sonar tab) and the "Lower Depth" setting (under the Sonar express menu) are 2 completely different settings with completely different functions...

The "Max Depth" setting is telling the processor to only "listen" for the returning echo "ping" from the setting value entered before the unit sends out the next "ping"...(this is a processor setting)

The "Lower Range" setting is merely telling the unit to only show on the 2d display down to a depth equal to the setting value...(this is a screen display setting)
