False/whisper signals

[fdl]

Today I found what use to be a 1 room schoolhouse but now is a manicured lawn & received permission to detect on it & so I did & came up empty. But I did get plenty of signals or high tones sometimes followed by low tones. What I mean is that as I sweep I would get a TID of 40 or 44 or 38 etc.,but,just for a split second......then as I would sweep back over the same spot-nothing,dead silence or sometimes I would receive a low tone as in a TID of -6 or -8. I would look at the depth gauge & almost in every case it would show 5 arrows or as being a deep target. My coil of choice was the 3kHz 9" concentric with a GB of around 25-40. The ground was very much trash free so I had my sensitivity set at 24-27. I ran in all metal.
#1 what are these split second signals? false signals?
#2 why, when I re sweep over this high tone, would it no longer be there?
I believe I have the X705 set up correctly so are these false or whisper signals? What is a whisper signal anyway? Just a little confused & still learning but having fun doing it. Thanks for any help.

What the dissapearing high tone is, is the machine telling you to slow down a little more. It needs time to properly ID the hit.
Now a low tone that turns high and then low again is a diggable target, as long as the high tone is in the middle. You should be able to isolate it for repeatability (the Minelab "wiggle"), and it should be pinpoint-able.

The 3kHz coils don't tend to "whisper". They tend to holler! Even on [size=x-small]small[/size] high conductors. It takes some time to learn to judge target size/proximity by the tone. Put a few more hours in and it will start to click.

ETA: In manicured lawns especially, repeatability is a must.

Thanks again Old Longhair. Your info. makes it clearer & I'm starting to get the target sizing down a bit. Last weekend at an old homestead I must have dug 2 dozen beer/soda cans because of the solid high tones but I learned that the size of the target was so large that I new it was a can before I dug it-well it took a few cans but I figured it out.

When you're relic hunting you just about have to dig those anyway. You never know when a hit like that can be that legendary mason jar of gold coins.
Sounds like you're getting a grasp on it. You'll learn other things to help determine whether a signal is worth the effort. It comes with time.

Longhair nailed that one,,,, SLOW DOWN, lol

Your swinging way too fast. a 3 to 4 second swing speed is ideal....

IMHO, I wouldn't hunt nice manicured lawns with a new to me machine. Learning is best done at those old homesteads and ratty old yards where careful digging isn't so important. Old Longhair was right, at sites where it's possible some buried goodies are hiding, digging all good signals is a must. I once dug a bunch of beer cans(with a meterless shadow x2) and all of a sudden one of them turned into a nice old RR padlock. You just never know. Good luck and HH. Bob.

Point well taken. I really don't like detecting on peoples yards,especially around there homes unless I personally know them.I discovered this fact only after I started swinging my detector & became quit conscious of how I would dig my holes & how neat of a job I would putting it back. Needless to say I only dug 1 hole because I couldn't receive any strong,repeatable,high tones except for that one that turned out to be a piece of tin.
