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 not get an acceptable bottom signal, try turning up the sensi- tivity 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.

4.Most people can get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be abso- lutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe the bottom signal. You will need to figure some way to prop the transducer into position while you make your test run. A brick or two might be sufficient to hold it in place.

5.When you are satisfied with a location, mark it and proceed with the installation.
