I finally went to an FBS machine. Using the original 10" coil. Haven't had time to detect outside my back yard which I've hunted heavily in the past. Haven't found any coins or keepers yet (may be the location). The big deal is that I am digging at least twice as deep as I'm used to. I've found shallow to medium depth Mercs and Wheats and clad in my yard with my other machines. Now with this Explorer SE I'm getting deep (like 10"+) and I love it. I'm mostly using the SmartFind screen but checking some signals with Digital. I just added a probe yesterday and have to get used to it again. I've got a 6x8 SEF on the way and I'm sure I will get the 10x12 SEF as well. I will get a book too. Any advice or direction you can post would be much appreciated. Thank you. GL and HH. Matt
