Noise Cancel

[5900_XL-1]

I've now read three methods for the noise cancel routine.

1.MInelab seems to say hold the coil 12" parallel over the ground and stay still til finish.

2. Another system is to put the coil on the ground and cancel.

3. The best FBS and Explorer hunter I know personally, holds the coil waist high out in front to cancel.

Is there a "most right" method?

All you are doing in Noice Cancel is the machine, as far as I know, is detecting electrical interference. Once it detects interference it internally selects the best cancel it knows.
You can also change it yourself manually.

You can hold the coil over your head if you want to. You don't have to hold it waist high. Just go by what the manual says. After all, Minelab built the machine. They, of all people, should know how to do it.

Thanks. I went outside to my hardest to hit buried coin and used this method:

Placed the coil on a clean spot, THEN turned the machine on and let it settle. Immediately began a NC while still on the same spot. IMO, picking up that 10" buried coin was more repeatable than previous testing.

It saves not making the task of imagining 12" height above ground,and staying perfectly still. If there's not improvement, it's so darn close in integrity, it is what I will choose from now on. It works for me ;-)

I'm going to have to report you to Minelab. You aren't doing it right! LOL

^^^ is what I do, just let the coil sit flat on clean ground not moving while it cycles through the noise cancel. Not sure where that hold it up in the air thing came from. I hunted a site near Boston once, far off in the distance were a bunch of radio towers. If the coil was not flat on the ground major interference, even the X1 probe would pick that up if laying flat on the ground vs pointing at the ground. In other words don't go looking for trouble by aiming the coil in mid air like a radio telescope

I experimented with both methods early about 2000 (off the ground and on). I noticed no difference and have been noise cancelling on the turf ever since.
Not saying its the best method but, has worked just fine for me for a long long time.

I've done noise cancelling with coil on ground and a foot above ground.
