I have surfed the web, read numerous posts regarding fishfinders, spoken to friends who own them and I am not convinced that fishfinders are used to their full potential. It is an amazing tool that can be used to your advantage but if you do not know exactly what each piece of displayed information means and interprets why the heck have one. So how does one go about learning its proper use and capability without re-inventing the wheel? Are there training courses that one can attend.

even though these stuff were on sale at the boat show, it just feels better supporting a sealiner.:thankie
