Example of a second bottom signal. Unit is in 30 feet of water, with

range set at 80 feet and sensitivity set at 87 percent.

2. Next, take the transducer out of the water and place it in the water in

the sump of the boat, face down. (The transducer face is shown in the

figure on the following page.) Notice how the signal strength decreases.

The second bottom signal will probably disappear and the bottom signal

intensity will likely decrease.
3. Now move the transducer around to find the best location with the

strongest possible bottom signal. If you find a spot with an acceptable

bottom signal, mark the location and move on to step 4.
If you can't get an acceptable bottom signal, try turning up the sensitivity

by three or five keystrokes and then move the transducer around once

more. If you find a spot that works, mark it and move on to step 4.
If you have to turn up sensitivity by more than five keystrokes to get a

good signal, the transducer should be mounted on the outside of the

hull. This is especially true if you have to turn sensitivity all the way

up to get a decent bottom signal.
