I acquired some gold foil approx. 25X25 mm my AT Pro will detect it at 50mm low tone 25-32. None of my pin pointers will react. Is this normal ?

Yes
Most pin pointers do not work well on fine gold.
Not just weight, but shape as well.
A small bottle of alluvial gold will set a detector off but not a pin pointer.
Some pointers are better than others, but in the field with high mineralization etc... thats why the sdc2300 costs what it does.
A $250 pinpointer can not compete. ..
PS. I have a pointer that will detect fine gold... but needs more testing and at 0.18g it has to be within 5mm of the tip.

Yeah i wondered why no one used one Always see the old plastic scoop wave over the coil trick. Cheers.

Garrett will work on 2 grams nugget just fine. Forgot how deep .

Mine works on 0.06gm or less and it will see a tiny single layer of foil about the size of a match head.
so yes your pinpointer should be able to see such things, mine will see a 19x19mm piece of tin foil at about 30mm.
Even on larger pieces like my wedding ring can only be detected very close with a pin pointer

when you say close what do you call close, mine varies depending on the target, and also it runs at a lot higher frequency to most which is why it see's tiny bits. that was another reason I stayed away from the carrot and the TRX etc because they operate around 12 - 14 kHz, ??

A couple of centre metres. What I notice is that it's a lot closer than a similar size object made from other metals.

Well that is because your wedding band is quite pure which makes it low conductive, Hence for small Gold Nuggets and fine jewellery you need one that has a higher frequency, Most folks buy one that a mate says is good and No doubt they are but when you try to use them for something like Nuggets that is where you come undone, All those PP's that are Low frequency models IE 7 to 12khz range are made for general coin hunting, If you want to find Tiny things then you need something a lot higher, Pinpointers Like the MD20 that run at 300khz are just not practical for mixed use's because they can see the mineral content in your hands, A bit like LF nugget detectors do. So if you want one for tiny gold and fine chains etc you need one that operates up around 30-40khz,

Good info RR. Thanks
Spot on AM, my plastic scoop waved over the SDC is the best pinpointer. It will pick up fine super fine shards of metal a Minelab pinpointer has to be touching. But even it has its limits.
The other day I swung my pick into some Quartz mine dump rock and a superfine squiggle of metal shaved off the pick about 1cm long and about 1/10mm diameter. The SDC gave a very feint repeatable signal, the sort I am looking for to find micro gold in old mine tailings.
I chased this target around for a while, got a very clear target response on a couple of occasions but kept loosing it, so was thinking I had a specimen in rock.
Tried my pinpointer with no luck. Finally ended up with it in the scoop and then lost it, found it again, lost it, found it.
I was looking for rocks containing gold at that stage due to the nature of the target response as the SDC works similarly to a pinpointer, a couple of mm closer makes a massive difference in the response and depending on where a bit of gold is sitting in the rock, the very small stuff can be easily missed as a rock rolls under the skidplate or in the scoop. I find with the super small stuff that I need to take it out of the scoop and run the dirt directly over the back of the skidplate and rotate each rock or move the dirt to see if it has a response. The very edge of the coil being the most sensitive with the smallest bits screaming with the slightest of target movement in the hot zone.
After the word Fugget was proclaimed to the audience, I tested my pinpointer again with a signal only achievable when it was directly touching. An interesting thing with the SDC is that it is geometrically sensitive, I got an ear shattering response rolling the wire off the coil but deathly quite when sliding it off longways.
Lesson learnt = fuggets are Fuggets
....... but sound like gold

Even if a pin-pointer pings on small nuggets, you're still no where in front, as the thing is still in the dirt. All you would have achieved is a slightly narrower pin-point area. You still have to get it off the ground and separate it from the dirt, which is best done with a large flat'ish sided scoop.
My pinpointer always comes with me when I'm gold detecting, but it gets turned on on those bigger deeper targets, where you start to lose where they are in the hole - i.e. you lower your metal detector coil in the hole and it just goes berserk. If the Target is really big and you're swinging a GPX you can flick to Cancel and try to pinpoint it - but that is often easier said than done.
This is the type of hole where my Xpointer always gets used and saves a lot of blisters!

Have a Detexnix Pointer that will detect small gold but am sending the Nenad for field testing as it works for me .
Items are 0.1g 0.16g and 0.2g and will detect all 3 at 5mm distance - Air
Was going to try some more testing - but better to have it done by some one in the field.
Could be great for some specialised work in crevices etc but not water resistant/proof.

My PP hits 0.19 (0.2) bits between 25 to 30mm, most pinpointers are made for coin hunting which is why they range from 7khz to 12khz, On high conductive items like silver respond better to 7khz which is why this range of frequencies are the most common frequencies used in making metal detectors, One of the best if not THE best Coin machines ever made was made by minelab at it ran at 5khz.

I am yet to fully test the range of pinpointers I have at my disposal...
But the Nokta (new one) would only get the 0.2 at touching it.
Wader would not get them but did at times chirp on the 0.2
Wader Li - would find the 0.16 at touching but not the 0.2 ( shape of the nuget I think)
ProFind - all 3 at between 3mm and 5mm
Garrett propointer - nope none
Fake Garrett ProPointer - all 3 at 5 to 10mm
Nokta RS only the 0.2 at touching.
Also different on the side / length of the probe...
So what pin pointer are you using to detect a 0.2g at 20mm plus ?
Would expect a few to be interested in that one

For the Past 10 years I have always used the Whites Bullseye II because it runs at 36khz I have owned 3 now, I had the first one for 6 years and I had a spare at the same time which was still boxed and never used but my backpack got stolen while I was detecting not 25 feet away from me, $%&#, Lol.
I had a conversation with Whites about their shift to lower frequencies and they said that the new model could do it ALL well there are a few things I don't like about the newer TRX and the most annoying one is that it has pre set power settings where as mine is 100% variable so I can use it for other uses and having used one in the Building Trade I can Zoom in mm perfect finding screw heads in wall or tracing fine wires etc, With PP's that have pre set power setting that can result in me making 2 or 3 inch holes in walls etc (50-75mm), That's Not acceptable in a room where someone has spent 200,000 just doing up their kitchen,
That variable control also helps with being able to set it right on the edge at full power were as the pre set models could be either set too high or not high enough, I know the BE II is not water proof and not a sleek design but it works, and it see's very Tiny bits indeed, The whole concept of a pin pointer is to Zoom in on a Target, But everyone wants a pinpointer to see coins between 100-150mm, WHY ???? that is what the detector is for!! Having a PP seeing a coin it 6 inches is crazy their Soul purpose is to Locate small/Tiny items at close range within 1 to 3 inches,
If these low 7-12kHz pin pointers were any good for prospecting compared to my BE II running at 36khz, Then WHY does my MXT running at 13.887/9 kHz see a 0.03g test piece at 25 to 35mm yet my GMT running At 48khz see's the same piece between 70 to 125mm from memory ??
And yet I can buy the BE II for 45.00 / $90.00AUD and the TRX for 120.00 / $240.00 AUD, So considering how well the BE II works on Tiny Items and the fact I can get them 2 and a half times cheaper why on earth would I ever want anything else,
This Seeing coins at 4 to 6 inches Is of NO value, when you consider the size of Tiny Nuggets to a Dollar coin and I agree with Nenad with what he says about using a scoop but when that Tiny nugget is still in the hole you need to know where abouts it is,
These are the things that are important when buying PP's, Don't get me wrong I like these newer models but they just Don't tick all the boxes and having pre set power setting does not Allow for fine Tuning,
Hope this Helps, John

The TRX does actually have 4 levels of power/sensitivity, it's just not widely advertised, even in the instructions.
If you want to zero in on a specific metal object in the ground, all you need to do is utilise the target ratcheting feature to narrow down the detection area (essentially a quick grab ground balance). Each subsequent press of the button will narrow the detection area to the stage where you nearly have to have the pinpointer tip directly over the target. Once you move the pinpointer away from the target, pressing the control button again will restore the ground balance setting back to the original level. The TRX is by far the most sensitive of all the pinpointers I own.

Yes that ratcheting feature is a good one for sure and yours has paid for it's self since you got your new Deus,
I have noticed that with my PP depending on the metal and the shape really makes a difference to the detection depth, IE a 6mmx6mm piece of baco foil it will pick it up between 5 to 13mm and yet a flat piece 8mm round will signal from 13mm to 30mm,
And the smallest 0.19g test bit it will see it at 13mm, which is where the shape issue can become a problem, and on a 0.57g bit it see's it between 20mm out to 52mm.
