Appendix A
Proper transducer installation is key to getting the best performance from your new unit. If the
transducer lead is too short, extension cables are available from your Garmin dealer. DO NOT cut the
transducer lead or any part of the transducer cable, as this voids your warranty. The cable cannot be
spliced and connected to any existing (Garmin or non-Garmin) transducer cables.
Following are some tips and basic installation instructions for some popular transducers. Detailed
installation instructions are provided in the transducer kits. Some transducers may need to be installed
by a professional marine installer.
Transom Mount Installation
Transom Mount Transducer (depth/temp)
Mounting the Transducer
DO NOT mount the transducer behind strakes, struts,
fittings, water intake or discharge ports, or anything that
creates air bubbles, or causes the water to become turbulent.
It is important that the transducer be in clean (non-turbu-
lent) water for optimal performance.
