Well to be on the nice side...I think I may have a defective unit

I know if I post I will probably get a lot of haters jumping all over me saying I have my settings all wrong yada yada. I am still investigating this matter but remember on my unboxing when the disrimination mode was acting all out of whack. Well it pretty much does the same thing outdoors and is very hard to make stable. in discrim mode. However punching the control box helped a few times. Which leads me to believe it's something internal, but other times messing with the coil wire affects it too. I am not a noob (close but not completely) and I have not seen this kind of reaction on any other machine, I might dissect this machine. On another note I was up till 3am working on a field test/hunt video. I might make it private and get some opinions or I might go all out public. Opinions are appreciated. I wish BigWaveDave would get his already so I can have something to compare this to. Thanks guys.
