Set Keel Offset
This unit measures water depth from the face of the transducer. If the
transducer is 1 foot below the surface and the screen shows the water
depth as 30 feet, the actual depth is 31 feet, since the transducer is the
below the water surface. Keel Offset lets you calibrate the unit's depth
indicators to account for the distance from the face of the transducer and
the lowest part of the boat.
To set Keel Offset:
1. Measure the distance from the face of the transducer to the lowest part
of the boat. In this example, we will use 3.5 feet, which will be input as –
3.5 feet.
2. Press
MENU|MENU|↓ to SET KEEL OFFSET|ENT.
3. The Keel Offset dialog box appears. Press ↓ so the first character is
negative (–).
4. Press ↓ until the number shows – 3.5 and press
EXIT.
