Question on sounds

[samuel_schumaker]

Okay guys, question for ya. I have been noticing on some targets that i can get multiple different tones on them. Its hard to explain, but i may get just a hint of a good high pitched tone and do the wiggle and it will repeat and as i move my coil say back the tone starts to get lower but still repeating and sometimes i get tones like this that will range from nickel low clear up to high pitched and the crosshairs will literally move anywhere in the screen. I guess i need to start digging these i just cant understand how it can make such a big range of signals. Also do you ever notice on heavily rusted iron thats large how it can have a great high pitched signal with the crosshairs pegged top right but as you wiggle and move the coil over it it will just null. I assume this is falsing from the end of the piece of iron but it could probly sound similar to a coin mixed in with iron. Seems no matter how small of a wiggle i do in pinpoint mode the crosshairs will always stay top left and it sounds like its just one big target. Thanks for any insight. Sam

My guess is that because you are getting multiple sounds is that there is some other junk or targets in the same area and that maybe the reason for the different tones. Ground conditions can also be a factor for this. One way to help with this problem is to go to a smaller coil and you will get better separation from good targets and junk. Hope this may help and GL & HH.

just dig all sounds to learn what the detector is telling you this is the only way to learn

I am gonna start digging more of the wierd sounding signals but i havent dug them all yet because im afraid if i dug every target then it would look like a gopher was in the park. The grass is dormant and not the best lawn to begin with so its hard to keep it looking nice. After thinking about it , sounds like this could be about anything, including a pocket spill of coins. If you had multiple items right beside each other it could make a sound like this i suppose. I will just start digging them and find out. The thing i am having the hardest with is at old homesteads where there is a lot of iron, if i get a good signal in with the nulling its always just falsing or something off of a piece of rusted iron. I wonder if it will sound better if there actually is a coin mixed with iron? At these places i dont mind digging anything that sounds decent because they are usually just fields or pastures but i never come up with anyting but rusted iron. I am thinking about going am mode and ferous sounds at these sights. thanks

Another question, i asked this on another forum back when i first got my detector and it sounded like its a normal problem but i better ask here also. Why does the screen take so long to update on a target. I use sound as my most important factor as to wether or not im digging but i like to look at the screen to see whats going on. Why is it that the screen will not show a crosshair position until the threshold returns or else you swing back and get another tone? I have heard that it will react faster with less sensitivity but i have not tried to lower it that far. I just dont understand how the processor can process the target fast enough to respond with a tone but lags behind on the screen and literally wont even move til i stop swinging and let it catch up. Anyone else with thoughts on this? thanks, sam

What version of Explorer are you using?

Well, the id indicator will not move until it gets no signal again. So if you are hunting in an area with iron discriminated out you will have to wait until the threshold sound returns before the cursor will move to another spot. Sometimes if you are hunting a really trashy area the threshold may never return thus, the cursor will remain stuck. This is the way the explorer works - folks would like a better visual ID but it is what we have. Sometimes you can do a quick sweep over the target then quickly raise the coil up about two feet for the threshold to return and the cursor to give an indication.

The question about sounds - It sounds to me like you probably have a couple targets down there if it is going from nicklle to high tone. Normally you will get a tiny variation in tone on a coin and this is the mark of a good target (not that much variation though). A penny at say six inches will give you a little arpeggio of tones as you go over it. Like this - low penny tone - slightly higher penny tone - high penny tone - slightly lower penny tone - low penny tone, this actually has numerous steps between the lowest and highest. At any rate this is the tell-tale sign that you have a good coin signal. A flattened bottle cap will have the same high coin signal but it will be flat (lacking the high to low tone). I know this is not exactly what you were asking, but I thought you may like the tip.

You should investigate some of those unknown signals. For the most part though, if it sounds like junk - it probably is. Don't forget to use the raise-the-coil-up size determination. If you can get a nice strong signal at say a foot and a half up - it is something much bigger than a coin. Test out a quarter and see how high you can raise the coil and still get the signal. Then use that as a guideline when hunting.

Hope this helps HH - BF

" I use sound as my most important factor as to wether or not im digging" THAT my friend is The most important statement you've made!!! stick to it and don't worry about anything else - what version of Explorer are you using?

 

[samuel_schumaker]

Se pro. Sometimes i dont even look at the screen, i been running im around 21 listening for good high tones but i seem to be getting some very very high signals that repeat so i look at the screen and the crosshairs are right beside the iron mask line and it shows shallow. Like clad but the crosshairs are wrong. I pinpoint the best i can and dig and nothing, even with the sunray in the hole, nothing but a null. This just happened twice a half hour ago while i detected for a few mins on my lunch break. I am assuming rusted iron but i never found anything

 

[ExpIInut]

have you tried with NO iron mask?

 

[Big Fang Coin Biter]

Yea, it sounds like you found Iron. For one, the extra high tone is a giveaway if you are hunting in conductive tones. The second clue is that you are having trouble finding the target. Iron will sound like it is one place, then pinpoint off a bit and once dug, will be off a bit more.

If you really want to find the iron once you have opened the hole. Put your machine into pinpoint mode while using the probe. It takes a little practice since sometimes the thing sort of goes into reverse in pinpoint. I would suggest holding the probe close to the top edge of the hole, hit pinpoint and quickly put the probe into the hole. You should be able to easily locate the nulled out item. When you go into pinpoint if you get a loud signal as soon as you press the button, turn it off, then hold the probe close to the dirt, try pressing it again.

Brass will give a high tone when in conductive but hit top right - only it has a certain ping to it

In all probability you are hitting multiple targets and one of them is iron.

The other day just had to dig this way out hit and even though clad it turned out to be a zinc penny, nickle, dime and quarter coin spill so those that investigate get the goodies.

For what its worth iron in conductive just gives that telltale shrieky high pitched sound which is very obvious but certainly can be masking a good target.
