Depth and keel offset
The displayed depth is the distance from the
transducer on the boat to the bottom of the
water, plus or minus an offset which is called the
keel offset:
A positive
keel offset displays depth as
measured from a point
above
the transducer.
For example, if you set the offset to the
distance from the transducer to the surface, it
will display the depth from the surface to the
bottom of the water.
A
negative
keel offset displays depth as measured
from a point
below
the transducer.
For example, if you set the offset to minus the distance
from the transducer to the bottom of the keel, it will
display the depth from the bottom of the keel to the
bottom of the water.
