It's great technology that used correctly helps you to learn to read graphs and also with understanding the layout of the bays you are trying to learn.

It's also great technology for preparing for tournaments or quick fishing trips on areas that you have never fished before.

It's also great technology for becoming a leech........
{You can throw the knives and axes at me now. I've stated my feelings and I know advancements in technology are great for all of us and I also understand that once it breaks the surface of the water it becomes community property }

And yes I do own the program for the bays/ areas of the lakes that I fish and use them all the time for plotting new areas to sink beds in the lakes.
I personally think that the average ledge fisherman(long liner, spider rigger, or crank bait puller) can get better information from lake chips than the hydrographxs program but this is only my opinion also....
