Keel Offset; Temperature Calibration - Lowrance Mark-5x DSI Installation And Operation Manual

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 or from the
transducer to the water surface.
Transducer
Keel Offset (-3.5 feet)
Before setting keel offset, measure the distance
from the transducer
to the lowest part of
the keel. If the keel
is 3.5 feet below the
transducer, it will be input as –3.5 feet.

Temperature calibration

Calibrates data from a temp sensor with data
from another temperature source, to ensure
accuracy of temperature data.
Reset water distance
Resets water distance value to zero.
