Bottom type is a key point for fishing. Bottom species usually move according to the bottom type (mud, gravel, sand or rock). By connecting your existing echo sounder to TZ Professional, you will be able to record not only the depth (3D Bathymetric charts) but also the hardness! This will allow you to deduce the bottom type!
