Clean the chosen area of the hull before attaching the suction cup. Lo-
cate the transducer on the hull as shown in the following figure. Don't
allow the bracket to extend below the hull, because water pressure
against it can cause the suction cup to come off at speed.
Moisten the cup, then press it onto the hull as firmly as possible. Tie
the nylon cord to the boat and route the transducer cable to the sonar
unit. Your portable sonar is now ready for use.
