sonar + sonar quicksplit combo option.
Advanced
Noise rejection
Signal interference from bilge pumps, engine vibration and air
bubbles can clutter the sonar screen.
The noise rejection option filters the signal interference and reduces
on-screen clutter.
Surface clarity
Wave action, boat wakes and temperature inversion can cause
onscreen clutter near the surface.
The surface clarity option reduces surface clutter by decreasing the
sensitivity of the receiver near the surface.
Scroll speed
You can select the scrolling speed of the sonar image on the screen.
A high scroll speed will update the image faster, while a low scroll
speed will present a longer sonar history.
Ping speed
The Ping Speed controls the rate the transducer transmits into the
water. A high ping speed will make the image move fast on the
screen, while a low ping speed will present a longer history on the
screen.
Manual mode
Advanced user mode that restricts digital depth capability, so the
unit will only send sonar signals to the selected depth range. That al-
lows the display to continue smooth scrolling if the bottom depth is
out of transducer range. When the unit is in manual mode, you may
not receive any depth readings, or you may receive incorrect depth
information.
Log sonar data
You can record sonar data and save the file on to a SD card inserted
into the unit’s card reader. Log Sonar can be accessed from the
Advanced sonar menu and the Sonar settings menu.
