Try not to laugh about this too much, but this was a dream I had last night. I had a good fishing friend to come visit me, and we were talking about fishing monitors. He said he had just developed a new type of fish detector and would like to show how it worked. We went Cedar Creek Lake and took a number of photo's of the lake in different areas. He then brought out a spray can and sprayed the photo. After a few seconds, it revealed every size of fish, underwater structure, depth, lure you should use and color, and even how to work the lure. Maybe something to think about.
