The 15 inch coil I've seen hit a quarter size target at around 24 inches using 3Khz. Probably be closer to 12 to 15 inches max at the 18.75Khz setting. Not shabby as even most PI machines won't do better with the same size coil until you get into the big dollar equipment.
Thanks I sure appreciate the help as I stated before I asked this same question on two other forums and never did get a response on it was about to give up in searching the forums when I came across this one and decided to give it one more shot guess it just takes the rite one
