Sonar chart with Overlay Data turned on. This example shows
Depth, Water Temperature and the boat’s Water Speed.
Ping Speed & HyperScroll
Ping Speed controls the rate at which the transmitter and transducer
broadcast sonar sound waves — pings — into the water. The unit has a
default ping speed of 50 percent. At normal boating speeds, this
automatically provides enough return echoes to refresh the screen and
scroll the chart at maximum chart speed.
When you are running at high speeds, or just want the fastest possible
screen update, you may want to use the HyperScroll feature. When
you change the Ping Speed to any setting greater than 50 percent, the
unit automatically enters HyperScroll mode.These faster ping rates
allow you to maintain a high-detail picture on the screen.
When using HyperScroll, you may need to manually decrease the
sensitivity for optimum performance. Depending on water depth and
other conditions, HyperScroll may cause a second bottom echo to return
to the transducer. This can result in a large amount of clutter appearing
on the screen. If this occurs, just decrease the sensitivity to a level that
eliminates the clutter. When you turn off HyperScroll, you can return to
your original sensitivity level.
