Noise rejection
Filters out signal interference and reduces on-screen clutter.
TVG
Wave action and boat wakes 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.
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.
