Installation

Keel offset
All transducers measure water depth from the
transducer to the bottom. As a result, water depth
readings do not account for the distance from
the transducer to the keel/bottom of motor or
from the transducer to the water surface. Before
setting keel offset, measure the distance from
the transducer to the bottom of the motor - see
illustration next page.
