How do you noise cancel

[DaugBiscuit]

I know the manual tells you to hold your coil 12" above the ground and use an up-n-down motion to within about 1". I believe it was Andy Sabisch's book on both the Safari and the Explorer who suggested you hold the coil above the ground at search level without raising or lowering it (if not in Andy's book, that was the suggested way by users of these two machines on the forms); I used this technique with both the Safari and still do with the SE Pro and it works well. How do you do it with the CTX; do you go by the book or do you hold it at detecting level?

Thanks,
Don.....

Not sure if your you meant to say ground balance or noise cancel?

Actually it is Ground Balance where it tells you to raise and lower the coil, but with Noise Cancel it does tell you to hold it 12" off the ground. In either case, Minelab has always suggested the 12" off the ground and others prefer the detecting level stating that is actually where we detect, not 12" off the ground. I was wondering if you follow the manual or hold the coil at the detect level in both cases, Ground Balance and/or Noise Cancel.

Noise cancel in a "target free" location.

When I ground balance, I hold the coil above the ground (same spot when I noise cancel) and I push the coil to the ground (repeat until is says completed)

I just follow the manual. Not sure why you have to noise cancel above ground but I assume its because targets can act as a tuning fork and offset your balance. Kinda the same with ground balancing over metal.

I hold it about a foot off the ground and have been doing this since I got my Explorer Se Pro, then the E-trac and then the CTX. It seems to always have worked regardless of where I held the coil, however. I have done it with the coil just above the ground, the coil waste high and everything in between and it seems this function doesn't have spacial needs nearly as specific as you are making it. I would just hold it off the ground, over clean ground and hit noise cancel and call it a day. Hope this helped -Marc

Unless you have really bad ground, you don't need to GB. I was doing it but stopped and I can tell no difference. I'm still finding silvers.

With the Explorers, E-Trac and now the CTX I do a noise cancel about 12 inches off the ground so it can catch any stray signal which can be a problem from other detectors or electrical interference. Now on the CTX if you want to ground balance which I understand is used more if you run ground coin and that is where I will bob the coil until it says complete over a area where there is nothing under the coil.

I cancel by the way the people that designed the thing tell me to. I know they have a reason why.

I agree with Rick. One thing that I might add....... hold the bottom of the coil parallel to the ground when performing the NC. Since the coil acts as an "antennae" while in use, holding it as you would while detecting assures the most accurate Auto NC channel selection.
