question about deep signals

today when I got that deep wheat, at first pass I got a #42, then at another direction it gave me a 48, another angle was 30, another way was bouncing down into negative numbers and back up, but tone was high it did not give me the iron grunt

why does sometimes it displays a negative number however you get the high tone? I decided to dig it, and glad I did it was the 1916 wheat that was 7-8" deep. Even after I cut the plug and opened the hole it gave me a reading of 42-48 I get that a lot on deep wheats, anyone else experience that?
 
The X-70 audio will go deeper than meter and there always just slight delay that number will read out on display ant audio tone. This pretty much hold true with most dectrors. I have dug many super deep Relic in hard hit sites over 12inch Plus that will only slight High tone and Yes sometime an very weak Iron target {Low Tone} may be super deep good target. You just take Little soil/dirt off very weak signal and you be surprised how may targets will sound with Higher Tones. I personal hunt only in Two Tones , was Sen. set high as passable most 26-28 if machine stays stable. Meters are good to only certain depth , and sometimes Hunters spend to much time looking at number. Try hunting by the tones you hear first then open holes then attempt use meter to help in what target may be. Hope help Chuck Acton
 
I dunno. I have had my VDI go off and a sound, but when I hit pinpoint nothing id there? This has happened a few times. Different but still wierd, Beale.
 
I too have had the whisper high tone and experienced the same thing as numbers jumping everywhere. Took some dirt out then got a good reading and continued digging until the target was up top. One was a quarter and one was a dime. I had the same thing happen several times today but when the dirt was layed out to see (in the woods) nothing was there just a pile of dirt. I guess it depends what kind of ground you are hunting. This place today GB'ed at 2 to 4. I Dunno......I'll just dig it if it sounds good.
 
I actually thought something was wrong with my GBing but after 3 times it was balancing out the same. Different dirt..........
 
Goes, try thinking that the numbers displayed are actually in a circle and not a straight line... meaning that +48 and -8 are next to each other on that circle. That is why a lot of hunters also reject +48 when hunting in patterns to eliminate the iron wrap around. Hope this makes sense.

that I understand but a lot of times deep wheats will give me reading as high as 46-48 even after I open the hole
 
The audio response of most any TID detector will "go deeper" than an accurate target ID. I figure that TID on anything more than 5 or 6 inches deep is little more than a guess.

Personally, I've never had a coin bounce from 30 to 42 to 48, without having an adjacent target(s) or the coin being on edge. I'll stick to my "2 notch segments in either direction" comment I made over 3 years ago. I don't doubt that you are reporting what you saw. I've just never had the TID on a single coin target change that dramatically. But on the other hand, I don't watch the display. With multiple tone mode in all metal, the audio responses provide me a better source of information.

negative numbers and high tone.......since the same software drives both the audio response and display, I can't explain how that could happen. If it continues, I'd consider resetting the X-Terra. JMHO HH Randy
 
I've had Wheats hit as high as +44 which really fooled me into thinking I had a silver quarter but I've never had a coin signal bounce around that much without some trash being near by. I'm glad you decided to dig, I probably would have moved on and wrote that signal off as trash and missed the Wheat.
 
I have seen a multi signal over a target similar to what you have seen. The ground was clay and the hit was also a penny. GB came out to around 50-55 and was at a park near brackish water. I see this on pennys(medium tone) as dimes and quarters are solid high tones. I have noticed this with the penny sitting vertically. Sometimes, Ill get this in the 23-28 range and after knocking a little off the top the signal changes to a 4-6 and bounces to 10. This usually is an old tin can or piece of metal twisted up from a mower that is deep.

Today I had a solid 36 high tone and it was a 1/4" solid copper rod. The pinpoint was all over the place and this was a fun dig since it suprised me.
 
dimes and quarters lock on solid, pennies are all over the place depending on depth. What is the reason for restting the machine, and how do you do it?

I have never changed any settings are far as custom stuff, I just use all metal all the time, never use patterns
 
I ain't going to tell you to do this..... but if it were mine, I'd turn it on and remove the batteries while it is running. I'd leave them out for a minute or two, then reinstall them. After it booted up, I'd reset all the settings with the factory presets. The factory preset info is on page 46 of the 705 manual and on page 44 of the X-70 manual. Doing these things would convince me that there wasn't some "glitch" in my system settings. Oh, and one other thing I might try would be the Target ID Stability mode. JMHO HH Randy
 
Randy I have used target stability since day one. I can try the reset, but just not sure what it would be resetting because I have changed no settings. But I guess it won't hurt anything right? It just resets everything to the factory preset like I got it when it was new?
 
Target ID Stability

The X-Terra 70 has a fine Discrimination Scale, but this may result in some
instability of the displayed Target ID in some areas with highly mineralised soil.
In these cases, the Target ID numbers may be further stabilised by using the
Target ID Stabiliser. The Target Tone may not always match the stabilised Target ID.
 
I believe that the way most TID detectors with multitone audio work is that the audio is produced by continuously relaying what the receiver coil is receiving to the operator, while the target ID meter just displays the strongest signal peaks, in other words snapshots taken when the signal strength reaches its highest point over some small period of time. The TID smoothing works by increasing the length of time sampled to come up with the highest reading so it won't jump around as much since the sample size is larger.

I know the Teknetics T2 works this way as they discuss how all of this works in its manual so I would assume that the X-Terras work the same way since both detectors respond in a similar manner when you are considering the audio response versus the TID.
 
wow that was way above my head, you lost me..........

I reset my x-70 to factory presets, but it is raining out today, will report back when I go hunt again
 
Pinpointing "all over the place" is what I refer to when I've posted about target sizing and determining he shape of the buried object. When I get a target signal that is "bigger than expected", I switch my X-70 to the Prospecting mode and "trace" the object. Rods as you mentioned (or pieces of copper wire) will produce a target response that is long and narrow. If I am hunting for coins at an old farm site, I keep on walking as there are short (6 - 8 inch long) pieces of copper wire and tubing (old fuel lines) at some of the sites I hunt. By sizing the target and getting an idea as to it's shape, I know whether or not it is likely to be a coin. On the 705, I am able to use Pinpoint Sizing mode which accomplishes the same thing as Prospecting on the X-70, but gives a TID. Running in either Prospecting or Sizing Pinpoint also tells me instantly if there are multiple or adjacent targets. HH Randy
 
Goes4ever I get the same thing on wheats let us know if the reset helps.
On a second note was hunting with friends one mxt the other with explorer
and we all would swear silver dime but it was a wheat might just be the moist ground in the spring.
