LOL, now that's funny. 40 years ago Bill Dance was pushing the PH meter. I think it needed to be 7.5 for the best fishing water conditions. My friend who then owned a bait and tackle store tried one. He said when he lowered it in the water it would read good level, then move it 5 ft. next to a stickup and it would read totally different. I feel the same way about the color-c-lector gadget. I think this stuff was being pushed by Doug Hannon back then. The Bass Professor.
The class of young pros today on TV don't know what their missing out on do they?
Fish Formula, helicopter lure (the only lure you need, fish it vertical or horizontal). and on and on I could go.
