Art, I am so excited. I laid out a test field in my driveway. Targets were set up about 3 feet apart like this: #1 mashed 7up can with snap top remaining, #2 a nickel, #3 A dime, #4 a penny, #5 a quarter, #6 a snap top or pull tab off a Pepsi can, and finally #7 a Pepsi can minus the snap top or pull tab. I took two pill bottle caps and drilled holes thought them from side to side so the rods could be inserted and slid though both sides of the cap. Then I inserted a coin in each cap. First I started with dimes and walked to each target. The rods did not cross until I got to target 3 which was the dime. Next I inserted a pull tab in each cap after removing dimes of course. I walked to each target with the rods out in front of me as usual. The rods crossed not only at the pull tab, but also at the mashed 7 up can that still had a pull tab. I thought that was interesting. My next target was the nickel so I loaded nickels in the caps and walked to each target. As expected, the rods crossed at the nickel (see note on quarter). I got the same results with the penny and the quarter. Finally, I removed the pill caps from the rods and walked to each target. The rods crossed at each one. NOTE ON QUARTER: I did have a little blip between the nickel and quarter. Using the pill caps loaded with nickels, the rods crossed at the nickel target. For some reason they crossed again when I got to the quarter so I turned away from the quarter target until the rods opened, then I focused on the nickels and turned facing the quarter again, the rods stayed apart. I stepped back and walked to the nickel again and they crossed. Then I turned and returned to the quarter target another time and the rods stayed apart as they should have. I am convinced that my lack of concentration caused the blip because when I focused on what I was doing, the rods worked correctly. Anyway, this is so exciting to be able to isolate specific targets. I was going to attach empty Pepsi cans to the rods and test various targets, but decided to do that later.
