Well I got my F19 and within 10 minutes I had it together and took it to my test garden. I don't have to tell you guys there has been issues with some of the first F19's shipped out. I wasn't ready for what happened next. My coin garden is 20 years old. So it's pretty seasoned. I have a zinc, copper cent, nickel, clad dime and quarter all at 6 inches not including the grass. I also have one 3 ringer and nickel at 8 inches. Then one nickel at 10 inches. F19 set up with disc set to 40 with 100% sens. Yes this one goes to 100%. Stock 5x10 coil. It hit all 6 inch coins with ease and proper ID. So then I moved to the deepies. It hit the 8 inch .58 Minnie with no problem. I then moved to the 8 inch nickel. Yep it hit with proper id of 57. So then I swung over the 10 inch (all measured when burried) nickel. No problem with some id numbers that actually hit 57. Most were 52 -55 with some 57's. I was so pleased I called my hunting buddy Bill_S. I told him what just happened. He thought I was kidding. But I wasn't. In fact I don't think he ever fully believed me.LOL. So today after work Bill and I got together to compare targets with my etrac. We concentrated mostly on nickels. We would hit a nickel with one machine then verify with the other and dug. I think we found 7 nickels with 3 on end. Bill was now believing me. We dug a deep Wheatie too that hit nice with the F19 that the etrac wasn't so sure about. It was around 5 to 6 inches. Both machines gave lower numbers but we just had to see. Now for the real test. We dig an 8 inch measured hole and slapped a nickel in it. Bill said if it hits that he would be sold on the machine. It hit that nickel solid with correct id. I said lets dig it back up and put it down 10 inches. So we did. The F19 hit it every time repeatable with the numbers like I had in my test - 52-57. Next time were going to get it on video
