I just bought a silver sable umax, i have been hunting with disc on 3.5. When getting a target then turing disc up to ckeck type of target where would gold cut off on disc when i turn it up. Thanks Tom
 
Most gold rings read near pop tops/pull tabs, but depending on the karat, mass, and metal composition, they read all across the board. If you hope to dig gold rings, you have dig all of the other junk in that range, there are no two ways around it. But, one inportant thing with the Tesoro machines is, with tabs and pop tops, often you can get a broken signal if you alter your stance and rotate around the target. Junk will usually break up on some swings. Rings and coins, being so nice and round, will be strong and repeatable no mater which way you sweep them so any time you get a really stong, smooth, repeatalbe single in the tab range, DIG IT!

In the early 1990's one of the major manufacturers had an article in their periodical publication that stated you could reject foil, notch out tabs and find 85% of the jewelry you swung the coil over. Another manufacturer's publication stated 15% of gold rings would ID as nickels on their metered detectors. The first statement is pure BS and I haven't found the second to be very accurate, at least in my case it's been closer to 5% than 15%. A sad but true fact is the majority of gold jewelry falls in the same range as trash targets. Most of the girls and womens rings I've found were below nickels, in the mid to high foil range. Some white gold, platinum and tiny yellow gold rings were from barely above iron reject through small foil range. Most of the mens wedding bands, smaller boys class rings and older style girls class rings, along with assorted other medium sized rings, were in the tab range. It takes a really big gold ring to be in the zinc cent range, but I've found and returned several boys class rings that were in that range. I have yet to find a gold ring that was higher in the conductivity/conductance range than a zinc cent. The photo, except for one platinum and a few silver rings that are included, shows most of the gold jewelry I was fortunate to find over the last 15 or so years. The large ring with the black setting at bottom right in the photo is platinum, and it's kinda hard to believe but as big as it is it ID's just barely above the old pull off steel bottle caps on metered detectors, as did a 2009 girls platinum class ring I found and returned last year. The amount of foil, tabs, pencil eraser bands and other junk represented in that photo would be pretty amazing if it were all in one pile, but the check I got when I sold the gold jewelry to Midwest Refineries at $1,143 an ounce last December made digging the trash worthwhile:).

I agree JB, dead on. I've been detecting more years than I care to say, and my experience (water included) is exactly as you say.Great post!!
 
Yup JB nailed it.

I find more gold in the foil range than pull range myself. I must run my Compadre discrimination just above iron to get most gold to read well.
 
And I see some fairly thin chains in there too! If the chains were not found with a pendant or a big claw clasp, they probably were around iron or at the high end of iron on the discriminator. Discriminating out any foil would knock out the chains.
 
Scully is right..... alter your swing on a target and notice if it breaks up from different directions. If it does it's probably junk if the signal is strong it's likely a good target and should be dug. you can't get away from digging the junk if you want gold rings. It just aint happening with any detector. If they ever develop one I'll buy it but it's just not out there on the market.

Southwind, my new Compadre should be in this week and I plan to throw a nail or paperclip on the ground until it is just ignored or clicks and then hunt that way. Have you ever tried that? Thanks.
 
I've not found any gold yet, but have been digging many more nickles with my DeLeon since I bought it. I have opted to run in Disc mode, but with MIN discrimination, and use the meter to ID all the stray iron. If it reads over 20, I have been digging it.
 
I'D DIG ANY GOOD REPEATABLE SIGNAL, AS LONG AS IT IS SOLID FROM DIFFERENT DIRECTIONS..... IF IT BREAKS UP IT'S PROBABLY A JUNK TARGET.....
JUST MY OPINION.....
 
JB(MS) I came across this same message of your's on a diffrent message board (Sat Jun 03, 2006 8:06 pm) and it's helped me alot. You explained alot of useful stuff in it and helped me to finally decide to buy a Tesoro Comparde instead of a Teknetics Delta 4000 or Fisher F2.

I'm going to a dealer about an hour's drive away to buy the Tesoro Compadre this week.

Thank you!
