Do you noise cancel before starting?

[greedykind]

I have seen post that say you should noise cancel each time you change sensitivity and when starting a new search but, i have also seen post that they have been on a roll of luck and dont want to break the mojo so they havent noise cancelled in months!Does it make that big of a deal what channel you run on?Thanks for the input. charlie

I noise cancel every time I start hunting and anytime I feel that there is a change in ground conditions that is significant, like an area that has a lot of fill dirt hauled in or when I go from a grassy area to bare dirt.

Once I am ready to hunt I use noise cancel right after I power on. Then from time to time if the ground conditions change.

I used to do it everytime I went to a site, and here lately I only do it if I notice the etrac is not running smoothly and getting interference. Seems to be working fine.......

Every time I turn it on or if I notice I am geting closer to buildings or powerlines. Especially if it seems like the machine is not locking in on signals...

Thanks for reminding me!

The noise cancel has nothing to do with ground conditions. It only looks at surrounding EMF signals and picks the channel that avoids the worst of them.

I'm one of the superstitious ones. If I'm on a roll I won't ground balance unless the detector become unstable. When I'm ice cold I might ground balance a few times a day.

absolutely!

Exactly right Jason in Enid. I was just about to make the same comment, until I read yours.

Yes - every time I go out - before I start hunting and sometimes during the hunt if I'm out there for a a long time.

Any way to manual ground balance the E-Y=Trac? That would be nic ean dI'm sure would go alot deeper. Any thoughts?

Sorry guys, when you noise cancel ground conditions make a big differance on FBS detectors.When you noise cancel you are picking/scanning from 11 sets of the total 28 freq. during noise cancel the radio waves go into the ground and certain freq will generate EMF which causes EMI to be higher depending on ground IR and FBS detector will pick the best freq to run because different types of ground generate different freq and the FBS detectors null out or ignore the ground like blocking an unwanted scanner freq.Now if there is a lot of local EMI power lines,radio towers,defective transformers the detector it does not know the differance it is stupid so it will null out/ignore the strongest signal it reads during noise cancel the detector will next pick a freq that will make it run the best but may or may not get the depth you are use to.That is why sometimes it is wise getting away from from power lines noise cancel for the ground signal not stray EMI then go under wires because you may do a lot better.This is not ground canceling it is freq nulling/ignoring and that is why you should do it often it will make the target ID more accurate at deeper depths.The smart guys at minelab will tell you not to move your coil or have any iron under it when noise caneling you know why?Because it will analyse the rusty nail under the coil with the soil and null out the freq the combination generates and pick a freq that works in heavy iron soil which you may not be in.Andy does better job explaining in his books.He does it in one in simple statement it is ground IGNORING not GROUND COMPENSATING.
