the same as for all Humminbird flasher units. Use hardware provided to mount this base
to the boat.

screws, provided.

placed between the unit and the gimbal bracket Important: Note which side of the
gimbal faces forward. (Slots on gimbal bracket go towards rear). Also, rubber washer
must be located between the unit and the gimbal bracket.

to any desired position.
