Vexilar LC-8 - Manual (Page 12)

allows you to test all of the control panel and menu functions without
having to be on the water. It displays a short program of what you
may see when you are actually out on the water. Press the 2 key to
activate the simulator and the 1 key to deactivate it.
2 - OFFSET
Press the 2 key to enter the Keel Offset Submenu. The feature
allows you to compensate for the depth that the transducer is under
the surface of the water. For example, if you transducer sits a foot
below the surface when your boat is in the water than you would set
the Keel Offset to 1 foot. This foot will be added to the displayed
water depth. The depth that is displayed will now be accurate.
3 - RESET
Press the 5 key to enter the System Reset Submenu. Press the 2
key to erase all of your settings and return to the factory default set-
tings.
HIGH SPEED OPERATION
The LC-8 can read depths at almost any boat speed. Due to the
limited speed of the display, the displayed bottom may be some dis-
tance behind you, depending on how fast the boat is traveling Here
high speed is defined as any speed at or above the planning speed of
the boat. Once the boat starts to plane out, turbulence will develop
behind the transom. If your transducer is poorly mounted, the unit
will lose the bottom at a certain boat speed. This is due to all of the
air bubbles in the turbulent water. Readjustment of the transducer
mounting should solve this problem.
ICE FISHING
The stable platform of ice lets you concentrate on your bait and
the fish around it. The bottom becomes less important because it
never changes. The only movement on the display is of your bait and
fish.
