Coooool!
I have been doing it like this for a long time, dug a ton of trash learning but over the years I have settled into digging most targets that just come in solid when thumbing down, those with many or even just a few clicks, pops and noise before they firm up, most anyway, I usually leave in the ground.
The ones that come it totally silent, nothing and then they just appear, get dug every time all the way up and down the range.
Sometimes I do dig some of the noisy as they come in targets if I hear something in that tone that triggers my digging instincts.
Hard to explain exactly what I am hearing that makes me do this but it happens from time to time.
Overall a fairly rare occurrence and I can't recall many, if any, that were actually good targets on these but sometimes it is just better to be safe than sorry.
Masking trash can cause strange things to happen out there but I have so much confidence in the recovery speed and target separation abilities and that extra sharp disc range this thing has plus my surprisingly good track record avoiding most of the noisier trash it doesn't happen very often.
Observations...
Nickels are weird, as you can see that old one came in below the nickel area and I have come across many modern ones that came in a bit iffy, also not at the 5 cent mark and noisy but don't know why.
Most other coins just come in quiet...they just appear thumbing down but nickels maybe not.
The last time I took out my Compadre I found a 1917 buff in a very trashy site.
It was not the most solid signal, didn't hit right on the nickel spot either but I had found other buffs in this area before so I went after it anyway even though it was not within my digging rules.
This is why I never calibrate and adjust that knob to hit nickels dead on that 5 cent mark like some do, my preferred way is to have zincolns come in at exactly 3:00 all the time every time, and if they are in good shape and not eaten away they usually do on the small and 7" coil models.
I did find a tiny bit more play in this area using the 8" donut coil version but even that is not really a big deal.
The good thing is all the gold I have found with my Tesoros always came in quiet, even in that nickel range, sharp on the ends and solid.
None were deeper than 5" but most of my targets rarely lie deeper than 5-6".
That sta tab that came in solid, some trash will do that and you can't avoid it.
I do dig trash but most of it, (80-95% or so), will usually come in way noisier.
Exceptions are tabs like this that are flat in the ground and run parallel in relation to the coil surface.
Luckily most tabs are not laying exactly flat but at a slight or odd angle which tends to generate more noise thumbing down...those pops and clicks.
Other trash might come in solid too for several reasons, compressed pieces of layers if aluminum foil especially if they are coin shaped, condiment packages and those evil foil caps you peel off of drink bottles if they are flat in the ground and not crumpled up, certain shaped can slaw pieces, folded over beaver tail tabs laying flat and more, but the bulk of it does not in my observations.
I actually experimented on those foil peel off tops because they can be bothersome in trashy parks and found a way to ID most of them but that entails holding the coil up at a different angle which will usually generate more noise if you get that angle just right but it takes longer to do this and figure them out so I mostly just bite the bullet and dig them.
It's a numbers thing in this case, overall it takes less time to dig them and move on then to do all that coil manipulation stuff.
That, plus the fact that the ones that are solid come in at the same area and act exactly like some smaller gold foil area rings I have found.
Can't be lazy when you are looking for gold...even the smaller stuff.
Flattened steel old and rusty crown caps can fool you and come in pretty solid and noise free if they are also laying flat but on these they usually disc out at the top end and come in slightly lower as you thumb down thanks to that concentric coil.
They could come in just a hair lower, a very small move of that knob, but dimes, copper cents and quarters don't ever disc out at all so you can identify all of these different targets most of the time.
European Compadre versions sometimes come with DD coils and telling these apart these might be a problem on those models as they can be on any detectors using DD's.
On the USA Compadres not even an issue.
As I said I dug car loads of trash of all kinds in the past before I settled on these rules I dig by, as my confidence grew my trash digging went down so even if I do happen to miss something out there I don't know about it, I no longer worry about it and don't care.
I just figure I will catch it on the next visit, positive thinker that I am.
Most of the time hitting any target from a 90 degree direction will show the same behavior both ways whether it is on either good or bad targets, good is usually good from all directions and bad is usually bad from all directions...not many one way hits were ever good ones for me either over the years.
Others might have had different experiences on one way shallow hits but I gotta go with mine and what I have seen when I used to dig every one.
Iron rusty nails that can false into the higher coin ranges are usually different from two directions and they are usually not really solid, repeat in exactly the same spot or come in clear from any direction like coins do.
As far as speed with practice you can get really fast at this method even though you are spending that short time thumbing the knob making short swings over each target.
Hunting with others I still usually dig way more targets than most and considering the ones I do dig are more of the higher percentage solid types I usually do very well in the treasure area and still dig less trash.
I don't look at the knob position at all at first, I make side to side swings, usually with my disc set pretty low, and when I hear a solid sharp tone I stop and make some quick side to side swipes as I do that thumb up and slowly down thing.
Those that come in solid and clear with little or no noise I stop for half a second, glance at the knob position and then dig.
Once in awhile I do turn and hit targets from 90 degrees, a second opinion as it were, but most times single direction info is usually enough.
After doing this for so long on most I don't even have to look at the knob to have a pretty accurate idea of where it is pointing, I thumb up all the way to max most of the time and it is like my thumb knows how far down that knob travelled coming back but that comes from practice acquiring and thumbing over thousands upon thousands of signals...whether I ended up digging them or not.
Just my way if doing it, a high percentage way comparatively but digging the amount of trash I used to dig is no longer fun for me so I settled into this and still seem to find more than my share of great things even in heavy trash or iron.
If people want to set the knob and dig everything that beeps above it or dig all signals they come across out there that is fine if that is the way they want to do it.
There is no wrong way to do this hobby, just your particular way to enjoy it and we are all different.
Have fun, let us know how it goes.
