All metal : is it me?

[nick hunter]

Hi all.

I got myself a nearly new GT one month ago.

I love the unit and found already keepers with it, two gold rings, silver, etc.

I find it different (of course) and better (my humble opinion) than the Quattro (collecting dust ever since : will be a good backup).

Being a veteran Ther, I know how to ground balance a detector.

It's just that I notice that the response in disc is much deeper and audible than the response in all metal.

I know of course that deep targets can whisper in AM, but the deepest I hear are not that deep.

Plus I do not hear them easily.

Is it just me or am I missing something ?

Maybe you have the threashold too loud and it is drownding out the deeper wispers, it should be set to just audiable and no more, also the volume too low as this is just target volume, best up full or at least 80% you can always adjust it in the headphones(there is a difference). Do you have a steady threashold in All metal and not pulsing/wavering? if its not super stable you could have too much sensitivity.(hope you are in manual and not auto)
The sovereigns don't need ground balancing, although in AM you could use the tracking feature

Thanks kered;

I have a barely audible steady threshold, sens set at 11 o' clock .

Re-tried today : disc with this setting signals targets that AM does not.

I must say that deeper targets are easily pinpointed in the adequate mode, switching to track or fixed will silence the target.

I hunt beaches only, and am speaking of both dry and wet sand.

But I will give it another go tomorrow.

Thanks for your input.

Hey Nick

When I first got my GT I was using AM to hunt in, (in pinpoint mode). I read here that some, (more), preferred to hunt in Disc for those deeper targets. I tried it, (hunting in Disc), found a faint target that barely kicked the tone up from iron to a quarter pitch, (tone), switched to AM and pinpoint, and could hardly even hear that very, very, faint pinpoint sound over what WAS a deep quarter target. I KNOW I would have missed that whisper of a tone had I been hunting in AM / pinpoint so I now hunt in what I believe to be the best mode, and what I think most do around here, in Disc. I do think you can go a little faster in AM hunt mode as you will only hit on the medium deep targets, but you will be missing those deep ones.

I know I posted earlier that AM was working "in my opinion" best, I hope I did not make anyone miss any deep targets by saying that. My BAD! (Inexperienced).

My machine hunts deeper in DISC than AM.

Have hunted several place on the east coast and am is deeper, but have had a few that disc was deeper but only by a inch or so.Fresh water AM is always deeper in every where I have hunted.. Has it made a difference in my finds , Yes. I use all metal because it is deeper where I hunt and it is a diffused field which reachs out beyond the coil. The only time I don't use AM is when there is lots of trash or there are so many targets that with disc. you can pick & chose..had a site where there were thousands of coins and trash Mixed..so I used disc to pick thur and dig the low/midtones only coming home with several gold rings ........ I did miss a few silver items hunting like this, because Jeff from OCMD came behind me and pulled a couple silver dimes, and a silver ring........................Good Luck.....Joe

In disc the performance is amplified, this is why some find that they go deep in disc. What this means is that in ultra quiet ground you will hear some deep signals that you won't otherwise hear in am mode, but the detector is still reacting to them.

In am you can swing very fast and it won't make a difference in depth, in fact, I find that if you swing too slow you will miss targets. You also get targets outside the coil range, as the pick above demondstrates.

When you compare different modes, you need to try different ground types not just dry white sand. Try different settings with different modes as well, you will be supprised.

 

[nick hunter]

Thank,k you all for sharing advices with me. This is very interesting.

To be honest, I noticed that the P/P mode would be better heard than the "bare" AM mode, but I was kept from trying this because of the manual saying the unit could become erratic.

So I think I might give it a try, because I was really convinced, like many others, that AM was not as deep.

So I will try the reverse disc technique as described and illustrated by Oldbeechnut and see if I get some improvement.

A question for Oldbeechnut : I noticed the threshold on your video was loud. Is it needed, or was it just for ease of hearing on the film?

Thanks.

target in all metal i couldnt here in Disc.iv checked it many times to be sure im not missing anything and if it whispers in all metal it will tone in disc mode.i do know some detectors are diff but of the 7 Sovereing's iv owned they were all the same as far as that goes.but i have had some go deeper than others.

 

[OldBeechnut]

The loud threshold is to the Video Cam only for recording purposes to show what to listen for when you do have a deep target.

My Settings on the threshold are......Illustration below

This is in All Metal / Pinpoint only

No. 1 .........Position is where you should run the threshold, Just Audible & Steady. Average depth can be between 10 to 16 inch's on the deepeees

No. 2 .........Is where I set it, for I use Doc's Sound Amp...reason..there are signals here so faint you cannot hear them with the human ear, In My area, they can be as much as 16 to 20 inch's deep on a Quarter. These are the signals that you would miss without a PI detector or the sound amp.

No. 3..........


All metal works for me in my area, it may not in yours...I noticed SurfDigger has been using it in his last few videos...and he is hitting very deep with his Sovereign, CJC has been the one to write several chapters in his Advanced Methods Series on Gold & The Excalibur..In his Theory & Practices Book he writes...Those Hunters that work only in Discriminate are selling themselves short...Reverse Hunting is a learned skill which takes time to develop. My best advice to anyone is to get all his books on the sovereign, and Excalibur.................

But at the end of the day never forget that metal detecting is very site dependent and so what works well in one location will be lackluster in another. Use what works!


Good Luck...........Obn/Joe

Thank you, Oldbeechnut !

I tried the reverse disc this morning and started another thread about the great results !

Sounds interesting, does it really work?
In the book finding gold, silver and coins with the sovereign and excallibur. the subject of searching in all metal with pinpoint was briefly touched upon. With most detectors searching in pinpoint would be impossible. But I must try this out With My sovereign GT. I figure I must use the pump method to ground balance in tracking mode, then flip the switch to pinpoint. Is this correct? Is that all there is to it?
Thanks for the tip.

[nick hunter]

Yep !

That is exactly what I did.

Ground balancing (track) on the wet sand, then switching to P/P, and the thing worked fine.

I set the volume at 3 o' clock and the sens at 11. Above those settings, the threshold is not that stable.

I did not notice any change in performance when encountering thick black sands layers.

Try it and keep us posted !

Jason the pinpoint all metal mode and the tracking all metal mode are two different modes. setting the detector up in track mode and then going to pinpoint isnt doing you anything at all except putting you in another mode. in tracking mode you either track with it or you put it in fix and that locks in your present gb settings.
the pinpoint mode is the same as the all metal mode on the elite and all the other sovs (even the original sov but that also has a seperate gb setting all metal mode in addition to the pinpoint mode.

its fairly easy to see how they are different modes when you hunt with each, the tracking/fix mode in all metal gives a more broad response similiar to the disc mode and the pinpoint mode is very precise, a very narrowed signal.

if I havent explained it well enough any of the minelab techs might to do a better job explaining it to you.

now which is deeper, disc or all metal? seems to be a situational answer depending on where you are. in my area, I find the all metal mode quite a bit deeper and others have found otherwise,so it seems it depends on where you are.

hope this helps,
Neil
