Mounting Options

The StructureScan transducer can be
mounted on the transom, jackplate, step,
trolling motor or directly to your boat’s
hull.

When mounting it directly to the hull,
you must purchase a high-quality,
marine grade above- or below-waterline
sealant/adhesive compound.

Use the following table to determine
which mounting option is best suited to
your boat/installation preferences.

StructureScan Transducer Mounts

Keeps transducer in the water when the boat is •
on plane, allowing you to track bottom at high
speeds

Transducer angle can be adjusted so it is parallel •
with the water

Transducer more likely to collide with obstructions •
in the water and adds drag to the boat

Transducer is not in the water when boat is on •
plane; protects transducer and prevents drag
from transducer

Transducer angle can be adjusted so it is parallel •
with the water

Allows you to mount transducer without drilling •
holes in your boat

Does not track bottom when boat is on plane•

Bracket and Transducer assembly

The StructureScan bracket comes with four washers, two bolts and two nuts.

If you plan to mount the StructureScan transducer directly to the step (Step Mount)
or on the trolling motor, you do not need to assemble the bracket.
