I would love a question answered if it can be

[lakillian]

I am out hunting in my backyard. I have a signal that is bouncing between 71 and 93. It says it is 5" down but I have already dug 9" Can anyone guess what it might be? Or do you need more information. If you need more information, let me know what kind

Thanks again you guys are great!!

Sounds like something larger than a coin but deeper. (That depth scale is calibrated to an "average coin" . . . whatever that is).

Aluminum soda can or pie plate at 12"

Copper pipe at 18"

That, or you have TWO targets and have dug between them. That's why wide sweeps and "crossing the X" are important.

As you lift the coil between sweeps what happens? That is gradually increase the airspace after each sweep.

Have you got a pinpointer yet? They can be a big help in analyzing a hole and finding the target.

I gave up and filled the hole back in. I was digging and digging. I think I got down to 14 inches and quit. I have never dug a hole that deep before. It just doesn't feel right . I have a vibaprobe that I use. I was told to get the detector pro uni probe but I don't know if I can spend that much money. I hear the FX-1 is good but it doesn't sound like a pinpointer but a detector. It sounds as complicated to use as a metal detector LOL.

I did dig 2 clad dimes and a wheatie today in my back yard along with bunch of foil in two holes. I have yet to dig trash and get a good item too. I always recheck my hole after I find what ever sets my VibraProbe off.

I really would like to find something good in my yard next to my house. But I never get a good signal. They are all bouncy. I am thinking of getting the 5" coil wht do you suggest? I have been digging in Factory preset too.

 

[GreenMeanie]

How wide did you dig?
Maybe a target in the side of the hole?

 

[lakillian]

I dug two plugs it was probably about 6 inches wide. I just gave up. I guess I do that very easily LOL.

If you hadn't given up then you'd know for the next time.

"Note to self: 71 to 93 and bouncy could be a 1936 tractor transmission bell at 27" depth."

Hand field info.

Do you have a leech field or septic tank(s) in your yard? I have all kinds of plates (inspection ports) buried in my backyard for the leech field and settling tanks.

We also have buried cables out front for the phone service.

Smaller coil may help, especially in locating prior to digging and evaluating close together hits. Someday I'll get one for mine.

Turn the sensitivity down on the 11" coil to 30 or so and you'll get the same effect for depth reduction. Less falsing, too.

the reason it settled down was likely because you Re-groundbalanced, because it doesnt sound like you changed the freq.
Being a bit too positive will cause chatter, and the simple task of rebalancing may have made enough of a change to settle it down.
Changing the freq will not improve preformance UNLESS your experiencing interference.
The increments are just too small to make meaningful differences in performance on targets or ground types. Typically..... for those kinds of changes to occur, the changes in frequencys have to be a lot bigger. (Like the difference between 3 Khz for coins....and 50 Khz for gold). higher freqs tend to favor smaller low conductors (but dont penetrate the ground as well), and lower freqs tend to favor bigger higher conductive targets (Read deep silver), and peretrate the matrix better. Tiny changes like the ones on machines to help out with interference typically have no effect of performance, UNLESS they help remove unwanted interference, and then they can make a measurable difference............. Streak!

sorry for the reply I posted...should have been under another post..

its almost certianly DEEP iron. The high bouncy VDI gives it away..

best way to tell,,,,is find the exact center of the target, and sweep VERY briskly over the center. Iron will often Id FAR better when you do this. Also check the "footprint" of the target. Does it seem real wide? A coin will be narrower and tight. Also, raise the coil gradually as you sweep. Can you still get it good quite a ways off the ground? If so..it probably aint a coin! coins tend to be softer and 'smoother" sounding. Iron, even though it may ID like a coin sometimes..will always be louder and "harsher" sounding, and the VDI will often bounce high (wraparound effect). With a bit of practice..you'll be able to identify targets like this in the future. Still........the best way to be SURE is to dig that hole! Streak!

The depth indictor on most detectors is for coin sized objects.. Anything larger could be much deeper as you have found out. That's one thing I liked about my GTI 2500, it would also tell you the size of the object. Anything bigger than a silver dollar would null out most of the time. Well, except for buried aluminum cans and they would indicate silver all day long. Stupid cans! Monty
