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. 
However, 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, and the screen refresh rate and chart scroll speed can keep 
pace with the boat as it moves quickly over the bottom terrain. 
When using HyperScroll, you may also 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 during the next ping cycle, or sounding. This can result
