This was a very good video and help me make some observations about the machine. Looking at my machines I wont be adding the Simplex to my arsenal unless I start getting out dug by one lol. Is a good price and the design has addressed a lot of issues with that shaft. As for depth, pull out your F75 and compare it lol. But if your hitting a dime at 9 inches that's pretty good as my AT Pro will hit dimes all day at 12 inches. Its going to find targets and you do have options(features) that you don't normally get.
