Sometimes she's hot, sometimes she's not......

I have detected for 36 years, and through all those years, regardless of machine, I have made what I think is a valid observation, that sounds so off the wall in one way, and yet makes some sort of sense in another. I am curious if this observation is one shared with other folks.

Here goes:

There are days of detecting, when I swear that my machine is "tuned in" to dimes, or pennies, or nickels, or silver, etc. more so than would seem probable.

My main hunting partner back home has heard me say this many times. We will go hunting, and I just seem to hit specific targets sometimes. I have found 5 SLQ's in the past year, which is just outrageous where we live. He and I hunt the same areas, and he has found 0 SLQ's. There are times when my machine just says "I think today, I am going to find silver dimes" or "IH's" or pennies.

Now, I know from experience, let's say with the explorer or trac, that if you noise cancel around iron, or other buried objects, it changes the way the machine responds overall. I always make sure that I NC in clear ground. Any piece of metal may affect the way the machine acts. Same for Electrical interference from wires, etc. The coil size also makes a difference in that I have to hunt for a clear space sometimes with my 12 X 15 SEF, and there have been sometimes I have air NC'd it.

I have had an experience along the Texas Border, where I am currently working, just the other day. I have been searching an old park that has produced 18 silvers for me so far, the oldest a 1916 merc. In one day, I found 3 IH's in the space of an hour, widely apart in the park. My settings were Screen basically wide open, 2 lines closed, except for nails in the lower right hand corner, multi-tone, manual sens about 27, conductive. Not one single silver though. I have come to expect silver from this park every time. All my silver has been deep here, 8 inches, and the IH's were in the same region.

Here's the thing, four hours earlier, before I took a lunch break, I was hammering deep nickels, found four of those, all buffaloes. Not much difference in temp, humidity, ground conditions, just different response from the machine I swear. I had identical settings, except for the NCing.

My reasoning suggests that given optimum conditions, where I Noise Cancel at, in terms of targets which disrupt that signal, outside electrical interference, humidity, ground mineralization, and setttings on the machine, I should consistently produce the same kind of results, but I have observed this "Phenomena" many times through the years, and it kinda flies in the face of what should occur.

The most likely candidate for the reason I am seeing this, or is it "thinking" I am seeing this, is because of some small variable of my tuning in my machine. I am just curious if any of you other folks see anything like what I am trying to describe here.

Sometimes she's hot for dimes, sometimes, for pennies, sometimes she's just not hot. They call this etrac a silver magnet, and i have to agree overall. I have about 80 concrete hours on her, and my silver count has trended upward from my explorer days, and I have used that machine since they came out.

Okay, there it is. Let's hear some opinions from you guys. If I am nuts, it is the other me who wrote this.......

I'll be curious to hear what the experienced guys have to say.

I think you may be on to something. I'd like to know what the "better" way of Noise canceling might be so that the ground contents doesn't weaken signals from certain coins. That would be a great break through.

I know that I have found many wheat pennies and when I've run across a dime, some days the ETrac screams and some days you real have to be paying attention. There has to be something to what you've discovered.
 
about it...I'll go for weeks at a time WITHOUT noise cancelling if I'm on a good silver roll:bouncy:

To this day I have not noise cancelled on the E-Trac since the first part of September...over a month ago:smoke:

WHY???...because I'm a goof:)...and I don't want to mess up my mojo. I've found 20 silver in that 4 weeks with the E-Trac alone...and I don't want to "mess" it up.:crylol:

I do the same thing on the Explorers. If I feel I am "tuned" in and finding a lot of silver and injuns'...I'll go for weeks at a time before noise cancelling them too.

When I hit a short dry spell and go a hunt or 2 without finding silver...then I hit noise cancel and hope to start another good streak:crylol:

Sad part about my response....it's all 100% true:)...and it works for me:beers:

PS: up until last night...between the explorers and E-Trac.. I was on a 22 straight hunt streak of finding at least one silver.

Last night however I only hunted for 30 minutes and got skunked:smoke:

I don't consider that a true "hunt"...but "technically" my 22 straight hunt silver streak ended last night:cry:...so I might just have to noise cancel next hunt:rofl:

Am I telling others it's good to NOT noise cancel your detector often?...NO and NO again...but it works for me:cool:
 
Bryce is not joking at all about that. I have hunted with him and when we check signals with each other he won't even turn his machine OFF if he is on a roll. He would rather walk 20 ft away to prevent interference while I listen to his signal with my machine instead of taking the chance of messing the mojo. :rofl:
 
Good lord, now you've done it! :heh: Silver has been slow for me lately. Thursday got 9 wheat's and skunked to the bone on silver. Hit the same spot yesterday (always noise cancel when I first start) and got 8 more wheat's and finally snagged a Rosie. Next time out looks like I'm not noise canceling :twodetecting:
 
OK Bryce, I am going to parrot exactly what you are doing. There is a second park, where I found my last SLQ down in Falfurrias, Tx, on one of my forays along the border. Park has been used since 1930's, and WHO has ever heard of Falfurrias, Tx? LOL Not many detectorists, and the find of the SLQ is the only silver so far.

So, the next round of my hunting, no matter where I am at down there, and I start finding silver, I am headed to that park, and hunt for the deep ones. Will be interesting. I have religiously Noise Canceled, because, after all, I read instructions, ask directions, and color between the lines of life........or not!

Regardless, I will try that, and let ya'll know what if anything I see happen. If I go there and hammer silver, I may weld that puppy without ever Noise Canceling again. That won't work, but you know what I mean.

When you press Noise Cancel button the machine selects the quietest of 11 channels. If you turn off the machine and turn it back on, the same channel will be used until you do another Noise Cancel and there is a quieter channel. You can also select which cannel to use from the menu.
 
You know, Yeasty brings up a point. It was established years ago that differing frequencies yield various degrees of success for whatever your looking for......don't recall the particulars, but VLF would go deeper, but not react as well as upper freqs for coins......I will have to investigate the trac for what freqs I am using, but the same observation I have can be extended to previous machines, which were not FBS, and not minelab.

Humidity, temp, etc, can affect circuitry in some fashion I suspect. Freqs would be an easy answer, and I have not looked at the freqs to figure how much they might play a role in what I have believed I observed. Hmmmmm

Dennis, freq'd out
 
No matter what channel is selected either from the menu or automaticl from a Noise Cancel, the full spectrum of frequencies are received (from 1KHZ to 100KHZ). I believe that each channel is separated only slightly and has no effect on the recieved signal.
 
This is an interesting post and I want to thank you guys for leaning in on it. I usually noise cancel, but I know what you mean when it seems like you're just not "into" the finds and that can play real funky on your whole approach to the day.

What's weird is noise cancelling twice at the same spot, back to back and having the machine select different channels. Go figure that on out.

I'm going to try to keep from noise cancelling when the machine's on a roll and see what turns up too!

Thanks Dennis.

I find a place in all metal that is quiet set my program and noise cancel and no longer have the problems you mentioned. I've wondered even if it is quiet under your coil does noise cancel accept discrimination from a factory or personal set program? If it does'nt that could be why some signals are stronger at different times. Just a thought. HH :minelab:
 
on a given hunt.I have zero faith in the Mojo thing .Positive mind set is quite another thing because if you are not "into" the hunt and do not expect to find anything you generally will not do well for lack of concentration if for no other reason..

Obvious things like changing soil conditions ,grass height and operator fatigue all play a role in ability to make recoveries.Optimum settings for site and conditions also play a large role in recoveries.I also think luck plays a big role in as far as walking over those exact 1" + squares containing the good targets out of the hundreds of thousands of square inches of area to be covered.It is a game of high odds and they are stacked against us but the E-Trac gives us the best odds of any machine :detecting:

I think the machines I used 20-35 years ago were much more susceptible to heat,cold and humidity than the E-Trac and much harder to keep "fine tuned" for peak performance.

I have done extensive testing of deep coin targets while changing the noise channels and found little to no effect on detection abilities.I like to noise cancel in mode I plan to use at given site while in manual 30 sensitivity and it has worked very well for me.If I am at a site with little to no EMI I will not worry much about noise cancellation.

However I say more power to any person and whatever they believe will help them be more successful:thumbup:
 
...what channel is your machine currently on? Might be something to it, if everyone on a streak is on the same channel...
 
What Ray-Mo said!
 
I personally noise cancel to see what it will read then put the E Trac in 9 most of the time, The E Trac has let me know that no matter what coins are there that have not been found yet at all for one reason or another. I FEEL like I have better success or MORE confidence in channel 9. What I have noticed also is that my deepest finds come on channel 9. Spooky huh! However I did sit down the other day to cut a deep plug and crushed my voodoo/mojo doll in my back pocket and I just don't know anymore. lol
