Today, I received, my simplex. I'm so jazzed. So far, as I'm taking up my backyard. I have found 15 cents, aluminum, and decking screws. Thank you, your one of the few people I have been watching and learning from. I have maybe ,Avery stupid question,. But, when I find the signal, where in relation to the coil should I start digging? Again, I'm a newbie, but want to learn. Thank you. Dave. NC.
