USING THE PLATINUM ID 120
OPERATING INSTRUCTIONS
7. Using Bottom-Lock
Factory Setting: OFF
Bottom-Lock provides an up-close view like
Zoom Range, except that in this case the
zoomed view automatically moves up or down
to stay on the bottom. To use this feature,
select BOTTOM LOCK and press ON-OFF. The
range of the display is shown when Bottom-
Lock is on.
This is an ideal feature for finding structure or
locating fish near the bottom.
Remember: If Bottom-Lock is the last function
you selected, you can use the ON-OFF button
to switch Bottom-Lock on and off without having
to press SELECT first.
8. Display Speed
Factory Setting: One level below
maximum
The Platinum ID is “updated” (advances across
the screen) as you move through the water.
The speed at which the display is updated
depends on the Display Speed setting. To
adjust it, select DISPLAY SPEED, and press
the Up arrow button for a faster setting or the
Down arrow button for a slower setting.
In general, higher Display Speed settings
provide faster updates, while slower Display
Speeds provide more detailed information.
