Advanced options
The Advanced option is only available when the cursor is not active.
Noise rejection
Signal interference from bilge pumps, engine vibration and air
bubbles can clutter the image.
The noise rejection option filters the signal interference and reduces
the on-screen clutter.
TVG
Wave action, boat wakes and temperature inversions can cause
onscreen clutter near the surface. The TVG (Time Variable Gain)
option reduces surface clutter by decreasing the sensitivity of the
receiver near the surface.
Ú
Note:
For optimal image return and clarity in most conditions,
the default value is set to a low value.
Scroll speed
You can select the scrolling speed of the image on the screen. A
high scroll speed updates the image fast, while a low scroll speed
presents a longer history.
Ú
Note:
In certain conditions it may be necessary to adjust the
scroll speed to get a more useful image. Such as adjusting the
image to a faster speed when vertically fishing without moving.
Ping speed
Ping speed controls the rate the transducer transmits the signal into
the water. By default, the ping speed is set to max. It may be
necessary to adjust the ping speed to limit interference or to adjust
for specific fishing conditions.
Start recording log data
You can start recording log data and save the file internally in the
unit, or save it onto a card inserted into the unit’s card reader.
The record function is activated from the
Advanced
menu option.
