Ping Speed
Ping Speed controls the rate the transducer uses to
send sonar waves into the water. A higher ping speed
will yield the best results when you are moving across
the water at a high rate of speed or fishing from a dock. The reverberation of too
much ping speed can cause interference on the screen.
When using two units on your boat, lowering the ping speed of one of the units will
prevent interference (cross-talk) caused by one transducer detecting pings from the
other transducer. The default setting is suitable for most conditions. Highlight
