To choose the proper location for shoot-thru-hull mounting, follow these 
testing procedures: (You may need a helper to complete these steps.) 
1. Anchor the boat in about 30 feet of water. Add a little water to the 

sump of the boat. Plug the transducer into the sonar unit, turn it on, 
then hold the transducer over the side of the boat in the water. Adjust 

the sensitivity and range controls until a second bottom echo is seen on 

the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range 
and ASP

™. Try a range setting that is two to three times the water 

depth. The harder (more rocky) the bottom, the easier it will be to get a 

second bottom signal.) Don't touch the controls once they've been set. 

 

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.
