Re: Fishfinder vs depth sensor

I have a small sailboat without instruments other than a compass. It would be nice to have depth and speed info so I can tell if all that tweaking of sail controls is working or not. The idea of a GPS/Fishfinder is very interesting because I like not having any holes in the hull below the waterline. Is the speed readout pretty instantaneous or more of a moving average?
