Target ID 42?

[redux2redux]

I've had my Xterra 705 for about a month and I feel I am getting to know it better each day.

But today I had a perplexing situation where I was digging at a very junky homestead site.

I was running in all metal mode and able to find some good targets.

At one spot I was getting a very solid/clean signal with a TID of 42 indicating depth of 4 arrows.

I did dig down and found a large piece of pipe at about 8", or what I am guessing is a large piece as
with a hole of 8-10" in diameter I could start to see a bit of curvature.

It was getting late so I filled the hole back in.

I am curious as to what kind of metal pipe would give a TID of 42, or is it the size of it that would
give that number.

Thanks!

A large rusty pipe. It's not all that unusual for a large rusty object to read well down into the silver range.

Whenever I get a strong, loud, deep signal, I always raise my coil 6"-1' over it to see if it still hits strong. If it does, it's larger than what I'm after and I move on.

That's a nice tip and i have to try that

If you use the pinpoint mode, you will most likely figure out when you have a find like that. A coin will pinpoint as a small, localized, well defined target, a pipe like that will be VERY loud and not very well defined as a target. Even if a coin is on top, it will pinpoint loud but still be very defined.

Copper pipe, lead pipe, and even rusty iron pipe can give high conductive numbers. As some have mentioned, raising the coil can be an effective way to determine if a target is much larger than a coin. And as others have mentioned, Pinpoint Mode (or Prospecting Mode) can help determine the size and/or shape of a target. The default Pinpoint Auto Mode will progressively mask the target response by automatically reducing the Sensitivity with each pass of the coil. Pinpoint Sizing Mode allows the user to maintain the Sensitivity at a constant level, allowing you to trace the size and general shape of the target. JMHO HH Randy

Thanks all for the suggestions!

I really need to learn the pinpoint sizing mode.

Getting to know the machine better and better each day and I love it.

Thanks,

Old rusty items will often come in at 42 on my 705. I use pinpoint sizing to eliminate most of the large targets however, if I have any doubt I still dig it. I get 42 a lot on rusty bottle caps especially when I am using my MF 10.5" coil. I can tell most of the time by centering the target and swinging back and forth over the target backwards until the target is just out of range and looking at the display it will usually read a negative number as it just moves out of range. I don't always trust it and dig some anyways but it has proven pretty reliable.

Great tip. Always nice to learn a new trick.

My most frustrating 42-44 TID's are old rusted bottle caps. Although others claim that the tone differs slightly from a quarter, I still cannot hear it.

 

[Old Longhair]

Bottlecaps hit with more of a Ppunch, or Bpunch sound (for lack of a better way to put it), while quarters are a more clean beep. Bottlecaps can also have a burble or broken tone, again while quarters are a clear single tone. Higher frequency coils make the difference in sound even more subtle, but still dissearnable.

Don't get me wrong, I still dig my share of the wretched things, but I avoid many more.

Did the pipe sound like a quarter surrounded by a ring of nails?

Thanks, That is very helpful and I will try to pay closer attention to the sounds you mention.
