9. Setting Depth Range
Factory Setting: ON (Automatic)
When you turn the Platinum ID on, it finds
the bottom, sets the ideal Depth Range,
and automatically adjusts the Depth
Range (to as much as 120') as the depth
changes. In this "Auto Depth Range"
mode, the bottom is blacked-in for easy-to-
understand readings.
If you prefer, you can turn Auto Depth
Range off. Select DEPTH RANGE, press
ON-OFF, and adjust the Depth Range with
the Up or Down arrow button.
In this "Manual Depth Range" mode, the
bottom is not blacked in. This lets you see
a "second return," which is preferred by
some fishermen because the width of the
second echo can indicate bottom hardness.
10. Trip Log
Factory Setting: OFF
The Platinum ID Trip Log provides a full
screen of information on current conditions.
To display it, select TRIP LOG and press
ON-OFF.
All log information is continuously updated
as long as the platinum ID remains powered
on. If you want to reset Average Speed,
elapsed tome, and Elapsed Distance, press
the STOP button.
Pressing ON-OFF exits the Trip Log and
returns you to normal Platinum ID operation.
NOTE: Trip Log requires proper input from
the speed accessory on the transom of the
boat.
