Dear Etrac Tom: Thanks for My 2 Mercs Today!!!

In a recent thread you taught me about "Tunking!" You said that you listen for that sound, along with a brief series of silver tones. It might be, you said, a deep silver. So this afternoon I was out and heard the tunk, just like you described. Much to my surprise I pulled out a Merc from the bottom of an 8" hole! About 30 minutes later the exact same thing happened. Tunk! Tunk! From the bottom of a 7" hole I pulled out another Merc. In both of these instances I would not have dug prior to your lesson on Tunking! I am amazed. And I am in debt to you. Sir, thanks for the terrific advice!
 
Nice!
 
WOW thanks WHITESMD for the kudos I really appreciate it. I'm not an ego tripper just trying to be a fellow detector user helper on these forums and don't bash others and or other machines like some on here like seem to relish doing.
You and I and others are on here to learn and help each other out right so I'm extremely glad I was able to do so. I'm by no means any kind of a detecting god or guru but I found out about this the strange hard way myself so thought I would share this tidbit about this machine the E-TRAC as it is an odd anomaly but good to know about this so you don't pass these types of target signals up without investigating a few of them in the area your hunting in to see what is up with them. Like you said You and I and I'm sure many, many, many others have and did pass these types of signals up too thinking junk iron or something or hot rock but not any more right Whitesmd!!!!!

This oddity can be on any target not just silver I've had it be Indian Heads and wheats and deep nickles too look at the numbers on the screen to kind of get a ballpark idea on these deep tunking targets. Open up to wide open quick mask to try to bring them in on the screen and in conductive sound with more clarity of sounds and CO and FE numbers and see where that cursor goes.

Not to bring up another Detector Brand on here in this forum but how I figured this out was I got an AT-PRO last winter for water and wet weather hunting and it was said that it could give a signal sound on a target deeper than the ID could give an ID no. on so you had to rely on the sound on these really deep targets 9-10 inches and deeper. I heard my first tunk sound consistently on the E-TRAC on that Indian Head penny sweep after sweep both directions and said to myself that it just had to be a target as it was so consistent not sporadic hits but it was odd getting that sound instead of the normal tones/sounds we usually get while in conductive mode.
It's sort of like running with FAST ON which also clips target sounds and kind of makes them tunk at the ends of the L-R - R-L - L-R sweeps over them. Who knew???? I don't recall any reference to this in Andy's book and I am in the process of re-reading it yet again for the umpteenth time. Always something new to be garnered out of there to try out too.

Thanks again, Glad to have helped out a fellow detectorist!!

Is there any way you could put that sound in a video ? I have heard sounds that I think are simular but haven't dug any . I thought they were a pressure type sound and have been looking for alternative sounds that people dig verses sounds that others know to be bad.
 
Mikeothmer I'm 53 and sad to say I don't have a digital camera/video recorder so no I don't have a way but maybe someone else now will but when you hear it and the depth meter is down there and every now and then you might get the right multi tone to go with the conductive number you're seeing on the screen you need to stop and check it out. It's the E-Trac reaching the depth of the range of detection for that particular target notice his 8" range starts to get harder for probably any detector after that point of depth on a dime maybe due to soil mineralization, or the angle it's lying in the ground, or dry or wet soil conditions, or another nearby target trying to hide/mask it etc.... I also don't even have any one around that I hunt with here just me so no possiability of someone else recording it either from here. It don't happen very often either just when you do experience it do not write it off right away check it out further and then you will learn it for next time right Whitesmd you owe me 2 silvers LOL HAHAHA. Congrats.
 
This was my first day of filming while detecting ever. On this day filming, I hit a Standing and Barber quarter about 3 feet apart. Both of those are FULL digs, but they're on different videos. That being said, here is the video of the SLQ, but the first signal was an iron false. BOTH produced the "thunking" type sound you're hearing.

The answer lies in Consistency of signal. I can't remember for sure, but I almost think at that time I was running Deep OFF or Fast OFF, I can't remember know...sorrry.

Thanks Neb Trac
That Video was great
I may have to watch it again because I donot beelieve I heard a THUNK
It was special to see you as a novice and I know many of us appreciate your efforts on our behalf
Hearing a deep Silver signal is so important and I am clearly not confident that I can identify that signal at this point
I wonder often if i am passing deep Silver but from the video it appeared that the numbers were still in place
I know that is not always the case but I will start looking at and listening to more video's with deep Silver and Etrac and hope
I get it enough from the video's to not miss out on the deep Silver in the future

Thanks Eva,

The "Thunk" is the sound at the end of a "warble". The deep type "grunt" so to speak just when the "warble" is gone. I can hear it at 0:38 seconds, 1:00 minute, 1:21 (all of which were on the barbwire). You can also hear it at 5:21 on the quarter. By the way there was no other iron or junk in the hole with the quarter. It is a straight coin find.

Also, I do not really get that "thunk" much anymore, or if I do I don't hear it. Every once in a while I hear it, but not much.

NebTrac
 
Wow! Besides all the thanks I owe to everyone who has helped me learn the Etrac on this forum, I want to especially thank Whitesmd for bringing the "thunking" subject to the forefront. I've been hearing it occasionally since I got the Etrac (in August), but never having seen it discussed dismissed it as unimportant; thanks Etrac Tom for actually investigating it and sharing that it actually CAN mean something; thanks NebTrac for defining the thunking sound with your video and also for "bringing us along" as you found your first Standing Liberty. That was too cool - almost like being there! Congratulations!

Thanks to everyone contributing here. I learn something every time I visit this forum!
 
Nice video Neb Trac.

That is not the "thunk" I'm referring to. Those sounded pretty typical to me and would have certainly recovered them. The thunk I'm taking about does not have any obvious high tones only a thunk. Those have been deep iron 100% of the time. The sounds in your video were what I get on all my deep coins in the city park. They all have a thunk at the end of the good tone I think that is just the nature of the beast. On shallow targets I get no thunk at the end, but all my deep ones do.
 
G4E got a thunk on his fishscale. I think I only get a sound like that on shallow clad, and it is like a small overload or something?
 
Nebtrac and South I think your both right it's like a signal but gets chopped at the end so you get some what of a multi sound and a tunk at the end kind of like when you run FAST ON you can clearly hear it as it cuts the signal shorter somewhat. May just be it's hard for the AUTO mode to see the target as it may be reaching the somewhat limits of it's detecting depth range so kind of clips the signal or maybe the objects are not flat. Could bve they are lying at an angle or verticle almost deep down so your signal is only a very small surface area compared to a full on face of a coin.

I'm almost sure I was running Fast ON here, as you observed Tom. I also agree that the coin orientation probably had a lot to do with it. Now the barbwire was a long ways down. I'm guessing close to the foot mark. I've been fooled by barbwire on several occasions at this spot. Again it was an iffy signal at best and the more I played with it, the more obvious it was becoming that the target probably wasn't going to be worthwhile.

I will say that on several occasions I've heard just the "thunk" type sound that SouthWind is talking about and the depth meter would bottom out. I think, when I first started, I would chase those signals and besides taking a long time to find the target, it was always junk, deep iron type stuff. So I hardly ever go after that type of sound anymore.

Terry (Goes4ever) told me about the "Kerthunk" sound some time ago but I can't say honestly if I ever heard it but I worked in a papermill for awhile and my hearing is not so hot. It would be interesting to see "hear" an example of it. Maybe somebody can replicate it on a video.
 
I replayed your video Neb and I think I got it now, the sound, the thunk is the dropping of the coin signal, I have heard it before. But I am not sure it is a silver indicator because I have had that same sound on clad I believe. I will try to pay more attention in the future.

Without violating confidentiality I will share an outrageous situation with you all

A major Industry in the USA that has been around for well over a 100 years was found to have made a decision that effected thousands

The executives distributed a memo that included a decision that rather than spend $.13 per man for ear protection plugs, they would roll the dice
and await to see how many men would become effected resulting in hearing loss and possibly lead to a lawsuit

They believed this tactic would save their Industry the most money

ULTIMATELY MANY MEN EVEN THOUSANDS BECAME HEARING IMPAIRED AND EVEN DEAF AS A RESULT OF THIS DECISION

This Decision had been made over 100 years ago and continued in the Industries policies even after there was confirmation that ear protection was a deterrent to hearing loss
 
Yes I thought you may have had FAST turned on as those signals weren't too offaly deep.

I usually run with fast and deep off and when I get targets 8" deep or deeper is when this sound occours so maybe the machine in AUTO +3 which is what I run in all the time is reaching the depth of it's detectable limits unless that sensitivity is quite high around here I get mostly 17-19 in Auto which isn't too much really barely half way on the range of sensitivity so my soil may be fairly mineralized here. OR maybe that fact that I run the coins discrimination pattern while in Auto mode also has something to do with and maybe it struggles a bit on raelly, really deep targetsso try the next suggestions and see what happens.
Try switching to a more open quick mask screen and or going into manual mode and see what this tells you to make a dig or not to dig decision. I find this gives more clarity to the target sound and numbers on iffy and deeper targets myself.

I go to manual mode 24-26 sensitivity after hitting an area in Auto+3 to re run it to see what may be deeper like one of you fellows did in this forum and discovered more targets missed that were really deep from when I was running in Auto mode first.
So I think this phenemenon happens on really, really deep targets in Auto mode and maybe on edge targets.
