Local offset
The difference between local time and UTC
(GMT). Change local offset when daylight
saving time starts and ends. The range is 0 to
± 13 hours, in 30 minute steps.
Temperature filter
Water turbulence and currents cause the
water temperature to fluctuate slightly.
To give stable readings, the Instrument
calculates these values by taking several
measurements and averaging them. Set the
Temperature filter to the lowest value which
gives stable readings. The range is 1 to 30
seconds or Off (0).
Keel Offset
A depth transducer measures depths below
where the transducer is mounted on the
boat, usually the bottom of the boat. The
Instrument calculates the depths to display by
adding the keel offset to all measured depths.
A
Have a zero keel offset to display depths
below the transducer.
B
Enter a positive keel offset to increase the
displayed depth. For example to display
the total depths below the surface, enter
the depth of the transducer below the
surface.
C
Enter a negative keel offset to decrease
the displayed depth. For example, to
display the depths of clear water below
the boat, enter minus the depth of the
deepest part of the boat below the
transducer.
