How will my echo sounder differentiate between echoes of different strengths?
A color echo sounder will use a different color for any one of up to 16 different signal strengths. This will make your strong returns show up as red and your weaker colors as green or blue. Monochrome sounders will use different levels of gray to show the different levels of signal strength. Strong returns such as a hard bottom will show up as a very dark color and items such as debris in the water or concentrations of plankton will appear as a cloudy gray. Back to top.
