Thanks Uk Brian.
I am getting used to it a little better now.I downloaded the manual from Garrett,and also downloaded the catalog from the treasure site from 1978 also.
I went out yesterday and practiced in a yard and was able to hit a lot of iron items,but i was digging everything to see what things are,how deep,and what they are.
I think i am good on iron now.I also dug up 2 little pieces of foil,and i mean little.They where just a very thin sheet,like a piece torn from a cigarette pack. About the size of a nickel.
Now i also know what they mean about the sound being across the width of the coil,or underneath it.
Kinda like a bong, bip thing.
I have been running in all metal,but had the power on,sensitivity knob all the way on high.Will have to decrease a littl and play with it.
Just got the ground balance figured out properly, and setting the knob for the threshold i figured was why they removed the knob.The book says once this is set,its done with.
On mine i noticed in order for the hum to just sound off,the stem is turned pretty far to the right.Almost to the end of its turning radius.
Is that about right?

Mmmmm...I managed to get my lovely Groundhog stolen so can't check the range but I doubt if it should be near the end of range but I wouldn't worry to much if the machine appears to be working fine. Could be an indication of something further down the circuit but I had similar with a P.I. ten years back and it never got worse.

By the way the slot is directly across,or horizontal from left to right,it is 3/4 turned to max.
But,i was out today,at a very large lot,with an old house,and a church that was built maybe 5 years ago.(The house is way older).
This lot measures at least about a half acre.
Anyway,in the center of pic you can see a cloth button,Reddish colored. It is steel center.
then below a rivet from a set of jeans, that is copper or brass,then below that,
a head off of a roofing nail used for tin roofs.It is the top,and is made out of lead.
So,although a lot of trash i found,i did find a very small piece of lead,and copper or brass.Out of this big lot.
So i think i am getting better.All where down about 3 inches,maybe 4.
The 2 items on left,are nails.Yes, that much mineralization,ect in my ground. I live around copper mines. And digging is no fun when i run into Caleche.
Anyway,penny is just for size.

IT COULD BE A VALUABLE PRIZE "YOU NEVER KNOW"
Check with Keith at www.brokendetector.com he has parts for most old Garretts........that is if you need any more hard to find parts.

Keppy,thanks for the info.
Actually i am looking for a 10-1/2 inch co-planer coil.

Wonder who decided to call it the "Featherweight" model ? Heavy old thing (4lbs 6oz) even without the extra two batteries of the Deepseeker version. Only made an armrest for the Deepseeker and BFO's in the first year or two though there was a three way universal hip mount for all models.

Mine has the armrest on it held by 2 screw type hose clamps.
The jeans rivet i found after cleaned up a little,has the words L S&Co, SF.
I looked online and it is from a pair of Levis,circa 1900 to about 1930.
It looks like the 1900 series for sure,but Levis changed the rivet some how before,or during WWII.
I looked at a couple sites about Levis collectables buttons and rivets.
I just received my adapter for the head phones,i tried it and it worked great. It is a single earpiece,and it uses a 3.5 jack,that is why i needed an adapter.
Plus because of critters,including bears and rattlesnakes,i wanted a single earpiece,and not double,or complete headphones.
Plus,people walking up behind me.

Sorry to hijack this, but I have a VLF/TR question. We just got one and I'm figuring everything out, but so far so good. We have the manual and the groundhog 8"ish coil.
My question is does the VLF Ground Zero Control do anything at all in TR? And does the TR selector do anything at all in VLF?
Jul 22, 2012, 11:07 PM
My model is the ADS Groundhog. It has the 2 position switch in the handle.It has the Auto/Manual switch on the lower left corner.
But the Garrett manual,and the one catalog,describe the same functions.
By the manual-If you operate in Vlf,with the switch in manual mode,the ground cancel mode is activated,and the Tr,is deactivated.
And in the Tr mode,the detector will NOT cancel out iron ground minerals in this mode.The Vlf mode has been canceled out.Or,the ground cancel control is non-funtional.
Also,read the 2 posts from occupant.I also copied and pasted his posts and put them in my binder.I also copied the catalog 1978 from here:
After you download it,print out pages 7-10.This explains a lot with pics. What i have done is take the Garrett manual,and the pages i referenced,and put them in a thin binder to use as a manual for myself.
Another easy way for me to remember the Ground Cancel Knob(top left),is this:
Push sound into ground= High minerals====Decrease knob
Pull sound from ground=Low minerals=====Increase knob
So in my terms,since i am pushing the sound,to the ground,i am using a Decreased effort.So i Decrease the knob.
So,when i am pulling the sound out of the ground,i am increasing my effort,so i increase the knob.
Hope this makes sense.It is an easy way for me to remember which way to turn the Ground Balance Knob.
I have only had my MD for 2 weeks now,so i am still learning.Next for me to learn is to use the TR function,to discriminate,or double discriminate to determine to dig,or not to dig.
So far i have just been digging every sound to learn.
Except for the double beep,or a long sound all the way across the coil.
Also,the newer Garrett Scorpion,and the new At pro,use the same hertz(15),and the same knobs,or functions.
They just took this great machine,and made it a little lighter,and look better for today's models.

Is Twin Circuit Just Another Name For VLF/TR.

You all might note my user name
And that was with intent! I teethed on the ADS, it was used to death - unfortunately, but it did last through the abuse I put it through from 3 years of hard searching. With that detector I even dug a balled up cigarette pack at 13". The whisper of deep silver was unmistakeable! It's only weakness was in those highly mineralized coal laden grounds.
I've even considered picking another one up. That beast could be trusted
Don't listen to the naysayers on this rugged, dependable, soon to be cherished tool!

Just picked up a 10.5 inch coil,new,to add to my groundhog.
I wonder what ever happened to occupant.
I have been pming and no answers.
He said he had lots of tips.
Got any tips about these 2 items,that the manual does not already describe or say.
QUOTE: tips on discrimination, determining the mineral content of the ground you're working over, ground balancing for best depth.UNQUOTE by occupant.
