Transducer is mounted on the fish finder after turning over the kayak. It can be mounted in four different ways. In case of portable unit, the transducer is fitted with suction cup. While for other units, it can be fitted on the flattest surface on the hull.nnOther ways of installation are from the scupper hole or at the back of the rudder. There are users who also hang the transducer on the side of the boat, but this is found to be damaging.
