talked with Mike Scott Earlier and he knows what is wrong

with the unit's... Looks like they were not aligned with a piece of ferrite properly.Said send it in a they would align it..Makes sense there must be internal g.b. pot ..Makes you wonder if the unit will suffer on the low conductor's ...Not really suffer but loose some of the punch the users have been seeing?

Either way they know about and can align/fix it!!

Yep. I was right. It was a ground balance setting. This is actually a good thing in one way as I always wondered how they set their gb ranges for the magnetic end of the ground canceling range. Knowing that they actually use a ferrite setting to adjust the magnetic range limits is a good thing.

The ferrite setting won't hurt the low conductors at all. They will just lower the magnetic range limits to allow the high conductors back in. Because that setting was too high, the ground balance was cancelling/masking the silver targets. Once that is corrected, the silver will be unmasked and you'll be good to go on both ends of the ground cancelling spectrum.

when they recalibrate it and you get it back, the Quick Grab still "nails" the correct setting in one pump of the coil. We've all seen where one pump isn't usually sufficient to correctly GB so this might shed some light as to if what you (Keith) were seeing was due to the ferrite unbalance or if there is an improvement in the QG function.
 
Was wondering about the fix and if it would end up 'hurting' the low conductor end and how the machine hits on gold and gold jewelry. I sent a PM to my dealer and told him if the problem is fixed at the sacrifice of less sensitivity to gold, then I want one of the problem children since I have plenty of coin shooting detectors and I am buying this one for GOLD.

Good to know ( and will probably be confirmed by my dealer) that the fix will not effect how the machine reacts and hits on gold targets.

Keith:

Because the electronics you are discussing are beyond my technical knowledge, this question may lack merit, so don't hesitate to say so if that is the case. But, I am wondering if realigning the ground balance with a piece of ferrite will then also mean that the amount of "chatter" the unit produces will increase significantly because it will be detecting a wider range of metals that are partially mask?
 
Not Keith but mostly likely the answer is no. My guess is that the ferrite imbalance also affects the large iron range as well. Perhaps more so the rusty heavy or irregular shaped iron that wraps around as high conductive targets. Wrap around got lots of attention on the new Fishers and Teks it seems to me. So getting the calibration right is likely more of an issue than just the high conductor problem Keith is seeing.

Discrimination as it relates to target ID does rely on a proper ground balance at least on the older analog units, not sure on the digital stuff where the target ID uses different filtering and is a seperate circuit. Chatter in the sense that you would hear more is a function of recovery/response time between targets which probably is unrelated to any calibration issues.

On the other hand I could be totally wrong. :lol:

aren't like the detectors of old..There are things going on that a nuclear physicist would have problems with:crazy:

I don't know if the internal adjustment is for keeping the target I.D. (Tone/numeric) aligned or if it controls the range of ground balance by setting a starting point for the machine to begin with on start-up???

I don't believe the T-2/f-75 has the internal setting?

I may be wrong and I hope I am but I am scared if the high conductors are allowed back into acceptance the smallest of non-ferrous targets will suffer..I am probably wrong on this but in my way of thinking it's got me wondering..

One reason I say this is because I could set the ground balance manually on the machine anywhere I wanted and still couldn't get the silver back ?

so the internal adjustment must be doing something more than just adjusting to a piece of ferrite?

Sorry couldn't really help but lets just wait and see what they can do with it..

Makes me wonder if the Cabella's version does this also?Anyone!!

The way the machine I had was set up it was pretty dang hot on low micro size but as the conductivity increased even towards say the upper 60 reading's the depth was dropping of pretty quick..

Is this from the alignment or is the Gold Bug even when aligned properly a more specialized machine? it is a gold machine ..( I have always seen high freq machine's have problems seeing larger targets at depth) and it was designed to find smaller items..

I wish I had a clear answer right now.. some people are saying it is super hot and deep on jewelry type items ( Beach Hunting) and has excellent stable depth in sand..that sound's encouraging ( Lets hope the alignment doesn't disturb this)..

Jackpine(Tom) was right it had real problems seeing plow point size iron ......,shovel heads also were hit and miss..

Another thing was when set at zero disc small iron backed buttons ( cuff Size) brass on front were non detectable no hit whatsoever ??( T-2 loves them heck that's what has dug most of them)

make any sense ..............Probably not:sad:

I think just to figure it out. Im still lost on mine, but I took it out side and found a pennie, and about 6 nails set at 20 dis, and had the sed all the way up. It still is hard to control. It makes so much noise and I don't' know what for.
 
Mine was as quite as I have ever seen but that might of been due to the internal adjustment being wrong.. Will your hit high conductors?

Keith
 
I can hit all kinds of clad coins. i havent tryed silver yet. I even found a penny in my driveway tonite. I kinda like it. It seems to just need some adjustments. I don't know how to set it up properley. I don't like the all metal mode. It makes to much noise. In Dis mode it is quiet, but turn it up in all metal and it is BZZZZ on every swing. Kinda crazy. Well Im going to play with it this weekend, and call Kellycodetectors on Monday to see if they can help me adjust the settings and to help me figure stuff out with it. Iv never had a detector in my life and don't really know what any thing means on it. I just want to go find stuff. lol... Well tku for the video it was helpful.
 
Having the circuit set properly so you can hit reliable on silver coin will not affect the gold part. It will just allow the acceptance of higher conductive silver. This I can tell you first hand.

Mr. Bill
 
The affected units hit ground balance readings of about 82 on ferrite. When corrected it will read 90, This is not a across the board problem with all Gold Bug SE's. IF they don't have a problem it will read 90 right out of the box.

There should be no concern about any affect on other metals when having a affected one adjusted, because most manufactured GB's, didn't have this problem.

I havent seen one ground balance on the first pump with Ground Grab. It takes a few pumps. At least here in my ground it does.
