In your unit, auto mode will let you increase sensitivity to 100 percent, but
the unit will limit your minimum setting. 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 adjustments to the sensitivity level, with a bias
toward the setting you selected.
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
water and bottom conditions, the bottom signal may completely
disappear from the screen when you reduce sensitivity to about 45
percent or less!
Try adjusting sensitivity in both auto and manual modes to see how
they work.
These figures show results of different sensitivity levels on the same
location. Fig. 1: Sensitivity at 98 percent, determined by Auto
Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 71
percent. Fig. 3: Sensitivity set at 47 percent. Fig. 4: Sensitivity set at
100 percent.
