I am about wore out looking at these videos and the racer's display never showed the higher numbers when crossing the penny and stayed down around 40. On the ATP video (rusty nails vs clean nails) there was no shot of the display but I could clearly hear that crisp high tone from the copper. The Omega did well also and showed pretty positive results. The longer and stronger I look at the Racer the more I find that does not measure up to the hype. More and better video tests would be welcomed, with some head to head tests. What videos done so far does represent a lot of work and they are greatly appreciated but as the interest raises the thirst for more in depth data begins to happen.
