I just got my E-Trac today from Backwoods Detector Sales and had about 15 minutes to try it out during lunch. I ran home and hit my back yard which has been hit pretty hard by my other detectors (Whites MXT, Tesoro Umax Silver, Quatro, and Explorer SE). I went straight to one corner of my back yard where I have found old coins in the past. I set her up for Fast Recovery, Deep, Difficult Ground, and used the Coin program. I noise cancelled and started swinging. About 5 minutes later I had a 1953D Wheat, in an area that I know I have used my other detectors on. The coin came through clearly on both visual and tones, it was about 3 inches down under a rusting nail. All I can say is wow!! I cannot wait until I finish Andy's book and get out to the beaches. I was also blown away by how much more balanced the E-Trac is over the Explorer. I know it is going to take some time to learn how to use this machine to its maximum potential, but it is going to be worth it.
