It Catchte, and I'm the new guy on the forum. Western N.C. starting to fish in the lakes hereabouts. I'm 77 young, retired, and looking to add a fish finder, or deapth finder, (I know so little, I don't even know the proper name) on my small bass boat, aluminum, 60 hp, 16ft. long. Primarily I want to know the deapth of the water, see where the fist are, and find productive structure. I have never used one before and know very little (nothing) about them. I don't need anything fancy, GPS or the like, and I generally don't fish in water more than 60 or 70 feet deep. I need something that is easy to read or interpret, and clear enough for old eyes to see. Buying it on a social security budget if you get my meaning. Hope you can give me an idea where to start and any recommendations or suggestions for purchase or use. Thanks alot for helping the new guy...............
