Fish finder manufacturers express the effectiveness of transmitter power in watts; however, many use the definition of “peak to peak,”
while others use RMS (Root Mean Square). Apart from Side Imaging and Down Imaging,
Hummingbird Fish Finders gives you a great many other options.
They make mounts for trolling motors, and in many cases have trolling motors
with transducers built directly in them.
