Depth Issue

[mtpockets]

At Times I'm finding that my SE seems to have trouble with Depth.....

Senerio:

I cut a plug to locate a target.... As I flip over the plug and check the Hole.... No Responce.... Ok So I run the coil over the bottom of the plug ( Dirt Portion)

Nothing no Sound..... BUT....... When I go to lay the plug properly back into the ground...... I run the coil over it and I get another good hit....

What Gives.....

It happens to everyone ay times. I can't explain it either but don't fret, it's normal.

Lift the coil and repinpoint. I sometimes find that my pinpoint is off and caused the depth reading to be off. By lifting the coil the pinpoint should center up better.

A good Sunray probe, Uniprobe or in my case Periscope will go a long way in finding those shallow targets. That saves you from digging too big of a hole, and extra time trying to find it once you have dug.

well I should have my Sunray X1 on Tuesday... I ordered through
Ron @ Dixie Detectors... I got a good deal.....

I don't use pinpoint mode....

But my thing is....Is am I missing objects due to this issue?

Come on How could you wave the coil over a target That's stuck in a plug you just dug and Not get a responce Jezz it's only say 2" from the bottom of the coil....

Makes me wonder a little..... I hate Glitches expecially if it means that I may be loosing targets.. Ya know..

1. The most common scenario: it was false signal from the rusted piece of iron, like a nail. When you disturbed the soil matrix, your Explorer recognized iron and discriminated it out. Solution: try again in Pinpoint mode or use no discrimination; do Minelab wiggle.

2. When you've flipped or removed the plug, you've placed a good target over bad one. Happens quite often in trashy areas. For example: if there is a coin in your plug, and iron pipe in the ground right under the place where you've flipped this plug... You get the idea. Solution: move the plug.

3. There is a bad target in the plug underneath a good target. Once you flip the plug - you have bad target masking out a good one. Solution: rotate/tilt and/or break the plug.

4. Your digging tool has put the coin on its edge in the hole or in the plug. When you use strict discrimination patterns, the coin on edge might be discriminated out. Solution: rotate/tilt and/or break the plug; carefully scrape walls of the hole; use target probe and/or Pinpoint mode.

5. Target stuck to the digging tool. Solution: check your digger

6. If you were too enthusiastic digging that deeeeep hole, the target might just go airborne. Solution: check the ground around the hole.

Hope it helps. HH!

Absolutely right. The first thing I do if I think a target might be shallow is to switch to the sunray and see if it'll pick it up. If it can't, I go back to the main coil and assume it's somewhat deep. If I can, I go to pinpoint mode and pinpoint it with the probe, which usually gets me to within an inch.

You have a very small target that is only a quarter-inch deep in the plug. Probably a tiny piece of aluminum or brass the size of a pencil lead or less. Once you flip the plug over it is too "deep" to hear (being so small). If you had a probe you could find it easily. A target like this is hard to locate.

The target in Mention is a coin target not trash....

These are all good excuses but this is a coin that's in the plug...

It gets a Little frustrating when you have to trash the plug to get the target

 

[scott (wi)]

... when you flip the plug over the coin is now further from the coil than during the initial hit, and might be at a worse orientation.

 

[mtpockets]

I think that some of us may be missing the point here just a little..

The plug itself is maybe 3" deep ....... When Inverted.... How can such a Powerful Detector .... Not Detect the Presence of the Metal content Within the plug when it's inverted....

It did just fine picking it up the first time Before I 'We" dig the plug....

This is becoming a common occurrence..

If this detector can detect up to 8,9 11" etc.. deep...

why can it not detect properly in a 3" plug....After all this is a Top of the line detector... I don't recall ever having this issue with my XLT... All I'm Askin

Try using pinpoint, it might tell you about your target by doing so. This happens to me from time to time and is usually atributed to carelessness of ther operator.

 

[mtpockets]

OK I will try using pinpoint...

BUT....

I find that this is becoming political Meaning.. We are going around the subject rather then addressing the Cause..

whether I use pinpoint or not Shouldn't the unit Still be able to pick up the target.. Yes or No

Why would I have to resort to using an after-market product to find my target..
I ordered the Sun Ray anyways so that I don't scratch the target...
Not so that I can detect with it..

I understand that I'm still learning the machine... But I just can't learn and understand Yet Why it will not pick up the main target...

 

[migolddigger]

I like this subject!! Have you ever considered that maybe the soil matrix deeper than the target you were reading was bad soil or highly mineralized? Old fire pits do this sometimes, or old coal dumps. If you dig deeper than the target and dig up the bad soil and put it on top of the good soil, the soil matrix changes.The Target can disappear. Like Trent said, you could have moved it, or possibly placed a bad target on top of it, or under it masking the target you desire to recover out. This can happen and does. I usually try moving some of the soil around and usually it will reappear. Having an X-1 probe from Sunray was the best purchase I have ever made for my Minelab Explorer II. So your on the right track. Give it some time you'll understand it better.

Got a signal pulled a plug and laid the plug upside down on the ground. Swong the coil over the hole and no signal. Swong the coil over the plug and no signal. Took some dirt off the bottom of the plug, still no signal. Flipped the plug over and got the signal. Waeded piece of foil. It's not the first time and won't be the last.

 

[Steve(MS)]

If you are detecting in extreme trashy areas, it could be an iron overload caused by metal under the ground that the detector is seeing causing it not to respond to the coin in the plug but it would have to be a lot of metal under the ground. If you found a coin in the plug for sure then that rules out a false signal. The other possible reason is extreme mineral content of the ground. Could be you have a faulty unit but if you have dug deep coins then that is not a problem. Tilted coin like already mentioned, if I loose the signal the first thing I do is turn the plug to see if that is it. I don't think this should be a regular occurrence.

I once had a guy come up from behind me and showed me the silver dimes that he found from my just dug hole's that I had lost the signal on, it happens. Still not sure exactly what happened other than the signal dissapeared after digging. And this was a manual tune deector that could not auto tune it out.

 

[James N.D.]

Me and my buddy Randy were detecting at an old Church Site (Church is long gone but there is a Cemetery still here) and he got a good signal that told him a Silver Dime. I went over it and it was a good Hit at about 3" deep. He dug a plug and popped it out and he couldn't find the target. I had to go over and check it with my detector once more and there was NO SIGNAL what so ever from the Hole or the Plug. I then switched on my Sunray X-1 Probe and checked the Plug. NOTHING! I then went into the Hole and got a solid Null. I then dug out more dirt and then seen a Silver Dime in the Pile I just removed out of the hole. I then dug just a bit more out and to our surprise, yet another Silver Dime came out. What the problem was here is that there was a High Content of Iron in the ground and it was masking the Target. With your scenario, I think that your Explorer was set too high for Sensitivity which in turn made the detector have lets say a "White Out" Effect and couldn't see the Target due to too much (A)Sensitivity, (B)Disturbed Ground, (C)No Halo, and (D)a possibility of too much Iron in the ground to see the target. This Phenomenon has happened to me a few time with Coins too so I always dig DEEP and remove PLENTY of DIRT and scan it with my Probe just in case of another one of these type of Targets. I also like to Pinpoint the Target with the Probe, then you will know for sure you are close to "the Target" or "one of the Targets" in the Hole. Hope this helps and Good Luck and HH.

 

[Schultzie]

I agree with James, too much sensitivity & trash near the target which is masking the target. A rusty nail can play games with your signal. Where I detect, I find lots of rusty iron "sag" it seems and it really messes with the signals I get but I am learning how to weed them out. Good luck and as posted in another thread..... keep it fun!
