I use the Iron Mask "OFF " as a filter to tame some of the noise in more minteralized soils .......Unconventional , but it works without me having to turn down my Sensitivity .....I don't hear much mention of folks hitting the Noise Cancel Band 1 and Band 2 switch to eliminate noise , and I was wondering how many of you use it ? ......What band do you usually start out using ? .....Thanks, JIm

I use band 2 to detect in and if i get electrical interference or another Sovereign close to me I will switch to band 1 and as soon as I can I will go back to band 2 as some of us when the GT came out did a few test and found in band 2 we felt the coin signals came in better, now whether they did or not we don't know 100%, but we felt it did.

I use band 2 also, around my house I get a lot of electrical interference (I assume it is anyway) in band 1.

I always hunt in band 2 too because people say it matches the ID charts for older Sovereigns that couldn't switch bands better. If I'm picking up RF noise my first thing is to lower sensitivity. If it's still bad and I'm getting real low (like past 3PM) on the dial then it's time to try band 1. If I flip over to 1 and it quiets down then I'll then raise the sensitivity until the RF comes back. Whichever band gives me higher stable operation without picking up the RF is the one I'll use then. I've been at sites where the RF noise was so bad in 2 bad non-existant in 1. Since I never hunt in one unless 2 doesn't work then I can't relate if there are sites where 1 is real bad but two is fine. I suspect there is. It's all based on the certain frequencies of noise the area has, as band 1 or 2 shifts all the frequencies slightly.
One thing I've never heard discussed by I've seen it past in the Explorer forums is that some of those guys believe certain bands will give more depth at certain sites, and they'll try to use them as a result in some way. What I'd like to know is what frequencies band 1 and 2 are at. That slight shift may indicate why one would be deeper than the other on the GT. If you look to the data on the Whites DFX they claim that the reason why they use two frequencies (I think 3khz and 15khz) is that both "spike" in their tests as to being the ones that generate the strongest magnetic field. Obviously a low frequency like say 3 to 6khz hits hardest on copper/silver coins, where as anything above about 12 or 14khz will hit hardest on gold. If White's findings are correct then I'd want to be using whichever band on the GT is putting out the same two frequencies (3 and 15). Regardless of all this, isn't it great that we've got all the frequencies being generated on the GT and so have the best of both worlds, along with insuring at least some will penerate various minerals better than others.

I have an Elite and I use the bands often... Like Critter, if I'm picking up EMI or RF noise I switch bands and usually one tends to be quieter then the other. I start in band 2 usually and switch back and forth at different sites to whichever band can holder a more steady threshold at higher sensitivity. Not sure why it varies from site to site unless that just means the EMI is not different in strength but actual signal type. For instance a site close to radio towers or one close to cell phone towers or one close to high tension lines... all different types of signal interference. Next time you get chatter or EMI interference try switchin bands, you may be surprised at the result.
i was thinking that too but not out loud, i'm sure it was a way of saying change to an etrac

Did some testing on the noise bands to see if one or the other was more sensitive based on the frequency shift in which channels are paid attention to on the receiving end of things. Wanted to see if this might offer more depth on either a high or low/mid conductor.
With band 1 raising the VDI # of nickels slightly and some other low or mid conductors a bit, to me that means that band might be paying attention to certain higher frequencies on the receiving end more. Meaning "lightening" up low/mid conductors better by biasing the frequencies it's watching more to the higher end of the scale, since higher freqs are often said to be more sensitive to low/mid conductors, and so perhaps would offer more depth on say a nickel, button, or gold ring.
Also, ran across from time to time in old posts that band 2 was rumored to be a bit deeper on high conductors like coins.
So I filmed this a while back to precisely measure the depths of both bands on a dime and a nickel to see what gives on that. Finally got around to editing the video for posting, with more editing in the works on others I filmed a while back, since the bad weather has pretty much ruled out doing anything else outside besides snowblowing...

When I first started hunting with the GT, I always kept it in band 1. I then got into some situations where I needed to elminate interference (ex WiFi, invisible fence) I would obviously switch over to band 2 and would usually cure the problem. However, there were times that niether band 1 or 2 would fix the problem and would have to turn my sensitivity all the way down. For the most part I now hunt in band 2 as it seems (to me anyways) that in this band I do not get as much interference from outside sources. There may be some scientific truth to whatyou are saying Rick. After all, if I am receiving less interference in band 2 as opposed to band 1, it would makes sense to me that signals would have more "clarity" to them. This year I will have to pay more attention when using / switching from band 1 / band 2.
