Noise Cancel????

[mickfin]

Wear do you hold the coil wen Noise Canceling??? At wast level / On the ground / on the ground away from a target, On Explorer Detectors???
Thanks, Mickfin

Instructions say about 10" to 12" above the ground, coil flat to (parallel to) the ground, holding the coil still until the process is done.

book also says to noise cancel often. if you hold the coil 12 inches above the ground it won't take long to be too tired to hunt. i've never noticed any difference after noise cancelling. it would seem that hoding it in the air you would be cancelling noises in the air so why the need to have the coil flat and parallel to the ground.

Do i got to find a spot with no targets in the ground??? I dident find that in the book thanks 4R looking sgoss66, Mickfin

i hadn't even thought about targets in the ground. you wouldn't think that it would matter since you're noise cancelling and not ground balancing. something else i've wondered about is when you first turn it on it seems to quickly go thru a series of channels like it does when you noise cancel but more quickly. if it is doing the same thing i guess it wouldn't be necessary to noise cancel when you first start up the detector

Chuck, KY Thats why i got a Explorer cozz thay dont need a G/B, If thy can`t see the minerals that mens More Deepth??? Right?? Thanks,
Thanks Steve on the Nose Cancel, Mickey,

You DO need to noise cancel when you start up (the tones you hear during startup are NOT a noise cancel); you don't need to find a "clean ground" spot -- as this is a noise cancel, not a ground balance. Finally, you hold it flat to the ground, because your detector picks up different interference with the coil in the vertical plane, versus the horizontal plane. Since you hunt with the coil horizontal, you also want to noise cancel horizontal, so that the machine can pick a frequency least affected by the types of interferences present which a "horizontal coil" would be picking up.

Thanks Steve, Mickfin,

then it would make more sense to do it with the coil on the ground instead of a foot in the air the manuel says. thanks

Not sure, chuck, why they want you to balance a foot in the air -- wondering if it IS so that you don't inadvertently end up atop a big piece of underground metal that might produce a "different" kind of intereference -- i.e. your machine is then trying to select a frequency that is "optimal" for rejecting interference, but is doing so while "seeing" signal from ground targets (which could throw off the optimal frequency selection process)?

Not sure.

Initially.... when first starting i put the coil on the ground to GB... thats what all those fast tones are. Then i raise it at swing heights to air balance and select a cleaner channel based on what the machine has chosen as a proper GB.

i've always swung the coil right on the coil on every machine i've used. not sure if i've found any more or less from doing it that way.
