Golden uMax. Good little detector.

[jabbo]

I bought one several months ago. Haven't used it much, but took it to a park today with the 7" concentric coil looking for gold jewelry. Didn't find any but dug some really deep scrap. Last week I buried a penny 6" in this park to test my other detectors. The Golden hit it hard in disc mode, sensitivity at 10 or better, 0 discrimination, the tone was iron. Today I buried a penny 7", the Golden gave a good signal on that one too, again low tone. Then I buried a penny 8" and still got a two-way signal, it was short but distinct and it needed a fast sweep. It didn't pick up the 8" penny with a slow sweep, seems to like a faster sweep for the deep stuff. Those deep iron signals are usually small iron junk, can't tell them from a deep coin. The soil here is mild and was damp today. Shortly after I got this detector I tweaked the pre-set GB trim pot, making it slightly positive. I think the tweaking added some depth to the disc mode. I bought the Golden for shallow gold jewelry, I could use it for deep coins too, digging a lot of rusty iron instead of pulltabs. Another thing I like is the 4 tones and the adjustable notch. I bought the 7" concentric coil for my Cortes but I think it will stay on the Golden. Jabbo

I have a golden UMax that I just trade for, mine seems to overload alot with the 8" brown donut coil. I have a 7 inch widescan coming next week and I hope with less ground coverage it won't overload as much. As you are looking at the circuit board is the ground pot on the left or the right?

It's on the left, the one on the right is for notch and tones. I don't remember if I turned it right or left to get a more positive ground balance. But it takes only very tiny turn to make a change. I was in my test garden and had the face plate off when I turned it. It's very delicate, be careful.

All those video prove is the camera is working.

I agree that the Golden as a great little detector.

Why do you think you are getting iron tones on your buried pennies?

Do you really think that getting a good solid "iron" tone on a penny at 6" is a good thing?

Has your notch/tone pot been adjusted out of factory specs? That will cause your tone id to be off. You should be getting correct tones at near max depth.

or even a quarter at 6" needs about 6 sweeps to change from low to high tone, at 7" stays low. Coins at 5" or less give high tone with 1 or 2 sweeps. I didn't touch the tones trimmer. Are you saying past 6" the Golden should give a high tone on coins? From what I learned on this board, ID accuracy drops off past 6" on most detectors. My Fisher ID Edge with 8" coil needs about two sweeps on the 6" coins for correct tone, but stays low on the 7" coin in my test garden. Same with my Cortes.

That doesn't sound right. My Golden would drop a tone, from the highest tone to the next highest tone, on copper pennies, dimes and quarters that were right at the edge of it's depth limit, and drop from a high tone to a mix of the two highest tones an inch or so before it reached it's depth limit, but it would never drop more than one tone down. That's typical of detectors that read downscale on deep targets in disc mode, which is most of them, and a lot of coins are left in the ground because of it. Some detectors will read upscale in disc mode though, my Barons do, and can move deep tabs up into the higher coin range, and small foil into the nickel range. Aggravating to dig an 8 or 9 inch deep tab hard ground, but I'd rather dig them thinking they're coins than leave an old coin a downscale reading detector moves down into the foil or iron range.

One poster found he had iron nails in his test bed when he cleaned it in all metal. Might wanna make sure the bed's clean.
