John, you sound just like myself. Im not sure that ive even turned one on in a year. I still try to read the shoreline, and contour depths from that. I know i cant see humps, depths, brush,etc. in 20' of water "unless i turn mine on" but then again, i think i do ok with flippin, pitchin, chuckin every stump, tree, hump, etc. that i do see.
One day, when i win the lottery, that i dont play, i will get me one of those $3000 GPS,Sonar,Digital,Catch all locators, but until then, I will keep my eyes on the bank.
Maybe if i went to BassPro during their Spring fishing seminars, and watched how to operate one, i may rely on it more.
