Using the SmartCast
The SmartCast is a first-of-its-kind wireless fishfinder that is incredibly easy to use.
Simply attach the Rod Mounted Display to your rod, then attach the Remote Sonar
Sensor (RSS) to the end of your fishing line and cast it into the water as you would a nor-
mal float or lure. Then power on the SmartCast RF20 and you are ready to fish. The
SmartCast system uses sonar technology to send sound waves from the RSS into the
water. The returned "echoes" are transmitted with wireless technology to the RF20 and
plotted on the display. New information appears on the right. As this information moves
to the left a very accurate picture of the underwater world is created, including objects
such as the bottom, fish, and structures, as well as the depth of the bottom.
