I'm once again overloaded with info smile I recently installed a Furuno chart plotter/fish finder on my dads boat that I think may be up to the job.If it works I just hope he doesn't miss it while i borrow it.

Greg I'm not one to underestimate the value of a professional and I understand the level of accuracy will be less then a pro survey. But if I can do it from my jon boat it will 1. allow me to look at my neighboring state owned ponds and 2.I feel at this point in time the money saved would be better spent with a pro later on.

While it has been a long day the Drdepth seems better then my dad's idea of a string strung across the lake with a weight and a sheet of graph paper laugh
