99 on vdi

[tymber79]

Got a question. Last night I got a strong 99 on vdi. Depth reading was 6-8 inches. I kept digging and digging but found nothing even with pin pointer. It got too dark to keep going, and my young son was with me and past his bedtime so I back filled the hole and left. I have heard dollars ring in about 99. Anything else?

Without knowing where you where hunting and hearing the sound you may have been over a big pipe which was much deeper than those six inches.

What kind of machine?

 

[tymber79]

At pro.

I've had those readings b4. Lots of times turned out to be a beer or pop can. It'll pick those cans up quite deep.

When I used my AT Pro, a 99 was always a large piece of iron. However, I have never found a Silver Dollar, so don't know about that.

Were you in an area that has buried pipes, sheet metal, etc.?

I got a 97-99 yesterday, I was thinking can however it wasn't super loud at about 2-4 inches and the signal dropped off when I swung the coil higher in the air unlike a large piece of aluminum. Well I dug it and pulled 2 Kennedy half dollars. The machine is fairly accurate for the depth for coins but can be off a few inches depending on the coin size. If it says 2-4 and I'm down to at least 8 it's usually large aluminum

Did same thing until I looked up and saw the garbage can.

Probably what you got was a totally rusted out iron piece of junk. It was rusted to the point where it was mixed with the soil matrix around it and not a solid piece. My half dollar coin ring I made for myself read 91, but is really easy to pinpoint and the Pro-Pointer can easily isolate it.

99 can be big silver. A large target is going to read much more shallow than it really is. I would check to see what size it is and how the signal edges sound. Iron is going to be wide and bleed at the edges from the rust halo.

Im pretty certain it isnt a coin, or even coins at that matter....Sounds like a large iron disc of some sorts.

I used to think the MORE Objects in one spot would make it read higher in numbers. But Last year i was finding 20 lb boxes full of ammuntion that were buried about 24" down....and even with all those copper/brass bullets.....the VDI still showed them in the mid-high 60s

If you got the pateince...i would dig it just to see what the hell it is!

good luck!

Make a slow sweep over it and see if it breaks up (iron).

Silver dollar I found rang in at a 96-97. 99 usually means junk and if you dug and can't find it prob an old pipe or iron culvert of some type.

 

[seabud]

on the AT Pro I've got one silver Peace Dollar it rang up at 95 94 and sounded clean 99 is almost junk

 

[tymber79]

Thank you all for the tips.

What can I say? I don't believe it. There comes a time you have to call B.S. This guy probably doesn't even own one. Those fisher guys don't like the AT series because it's eating into their sales big time. It's a big propaganda thing being pushed. I couldn't care less about fisher detectors. I couldn't even imagine going on the fisher page and raising a stink. Don't need to. It's just laughable these guys are so sucked into the propaganda. This ain't nothing new. It's been going on for decades.

did I miss something signal_line?

When I get a big number like that it's almost always a big chunk of copper or brass. A chunk of copper pipe tends to bounce a bit though.
