Adjusting sensitivity in Auto Sensitivity Mode is similar to manually 

adjusting a car's speed with the accelerator pedal while cruise control is 

on. You can tell the car to run faster, but when you let off the gas the 
cruise control automatically keeps you from running slower than the 

minimum speed setting. In your unit, auto mode will let you increase 
sensitivity to 100 percent, but the unit will limit your minimum set-

ting. This prevents you from turning sensitivity down too low to allow 

automatic bottom tracking. When you change the setting with auto 

turned on, the unit will continue to track the bottom and make minor ad-

justments to the sensitivity level, with a bias toward the setting you se-

lected. 
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a 
car without cruise control — you have complete manual control of the 

car's speed. In your unit, manual mode allows you to set sensitivity at 

100 percent (maximum) or zero percent (minimum.) Depending on wa-

ter and bottom conditions, the bottom signal may completely disappear 

from the screen when you reduce sensitivity to about 20 percent or less! 
Try adjusting sensitivity in both auto and manual modes to see how 

they work.
