What is the maximum horizontal profiling range for a 2D profiler?

In shallow water, the echo from the bottom or surface can dominate the return from the water column. The risk of getting a strong echo from the bottom increases as the acoustic energy pulse moves further away from the instrument, therefore impacting range. The maximum profiling range, R, can be estimated as R <15*h, where h is the distance from the instrument to the bottom. It is advised to mount the instrument in 2/3 of the water depth from the bottom for best range.
