Got it today. Took it out, found a nail. I dont know it if it is because of the wet georiga clay here or what, but i couldn't "dial" it in. The signals were here, there, then everywhere. Has anyone got one of these, and can help me with tuning it. I like it alot, but it seems to be kinda vague with stuff being in the ground. I re buried the nail, and it was like it couldnt find it anymore. Wierd. My wife got here Ace 250 today also. We have yet to break it out though. Thanks guys/gals.
