Mounting the Transducer

Proper transducer installation is key to getting the best performance

from your new Fishnder. If the transducer lead is too short,

extension cables are available from your Garmin dealer. Coil and

secure any excess cable.

DO NOT cut the transducer lead or any part

of the transducer cable, because cutting the transducer

cable voids your warranty. The cable cannot be spliced

and connected to any existing (Garmin or non-Garmin)

transducer cables.

The following pages contain tips and basic installation instructions

for some popular transducers. Detailed installation instructions are

provided in the transducer kits. Some transducers might have to be

installed by a professional marine installer.
