A solid 85 with high tone

[dlh]

I have tried to figure this out myself but I need some help. I just got the ATP 2 days ago and working on learning. In pro mode zero I got a solid high tone wth an 84-85 vdi. I dig and find a hinge. I was wondering what percentage of good sounding targets you dig turn out to be trash?

You guys might be sorry I bought this unit....lol

thanks

Is the hinge made of brass?

I Think you are right.......the hinge has a couple screws still in it and I used a magnet on both the hinge and the screws. It stuck to the screws and not the hinge. I thought possibly brass but wasnt sure where it would fall within the numbers. Thanks also for the link. A great reference.

Thanks for responding

No problem! Older hinges were made of brass because it's a low friction metal (which is also one of the reasons gun cartridges are often brass). It does ring up pretty high on the VDI scale. Brass is a copper/zinc alloy. The precise VDI number depends on the copper content.

Very few high tone 80's signals are trash. Bottlecaps are the exception, but in PRO mode you can easily tell a bottlecap. Large pieces if aluminum, pop/beer cans, and brass washers can also ring up in the 80's.

A good target like a coin or ring has a high tone but the tone drops off quickly. Do a test garden and put the hinge in the garden, you will hear the dif. Then practice pinpointing that will also help you determine the size of the object.

Good post! Coins pin point and drop off much faster tan bigger targets.

@ Diggin-it.-.........that is where I was confused. With that strong of a signal and the numbers not jumping around I thought for sure it may have been silver or something better then a hinge. Being I am just learning I thought maybe I had not done something right. But the good thing is I learned a little something. I also had switched over to the 5 x 8 coil just to see what the difference would be. Our house here is an older home with much trash. Right away I could see a difference in the separation of targets not to mention how easy it was to swing.

Thanks

84-85 is always a clad quarter on my machine with the occasional bottlecap or washer thrown in. Whenever I get 85+ and the signal area is larger than a quick blip (as said above, coins are quicker blips), I know it's trash, but I dig anyway b/c one day it will be a hoard of goodies. Keep swinging = keep learning.

I have noticed on occasion how the target can be larger then just a single sweep. I think what I am trying to say is with the 5 x 8 coil and maybe with the stock coil I can swing a coils length in front or in back of the of the original hit area and still get a strong signal. It appears to be a large target area. I kind of feel it would be a can, piece of copper tubing or some other large piece of trash.
