Identifying multiple targets simultaneously... Responses no longer allowed. If you have comments concerning multiple targets, please make a new post

The Target Trace image will not move up and down the screen. The Target Trace image represents placement of the ferrous and non-ferrous properties of the target(s), on the Smartscren. The images are color coded, based on signal strength. But if you have Pinpoint Target Trace implemented on your CTX 3030, the "trail" will build a stronger target trace image, until you release the pinpoint trigger. HH Randy
 
Yes
 
I'd venture to guess that the new processor has increased the speed. But in all honesty, speed became irrelavant once I realized how much stuff was under the dirt, that I'd never "seen" before. I continually found myself sweeping slower and slower, just to analyze all the targets. And I'm glad I did because it allowed me to pull some nice coins from some nasty - trashy sites. HH Randy
 
If I understand your ongoing questions, I'd venture to say you are still wrong in your understanding. The CTX 3030 does exactly what the brochure indicates....... it identifies multiple targets, simultaneously. Unfortunately, I'm out of ideas as to how I might better explain it to you. HH Randy

Let me lend an explanation & see if I get it right, please correct me if I am wrong.

If you are over ground spot"A" for example and there are 3 items directly below your coil, you will see all 3 targets on the screen and by moving the coil one direction or another, you will get the details of that target you are centered over but still being able to see the other 2 targets on the screen as long as they are in the vicinity of the coils circumference. Lets say 2 feet to the right in ground spot "B", there are 2 targets. As soon as you leave all the targets that can be located under your coil from spot A & move to spot B, you will see 2 targets on the screen and when under one of them, you see the details.
 
Thanks Don. Yes, it identifies multiple targets, simultaneously. I appreciate your effort to further explain it. HH Randy
 
I think maybe it is difficult to understand this in relation to regular VLF.

But atleast two possible solution as I mentioned earlier can be used.

1 it does send pulses to ID whatever is under the coil at any given spot ( in time ) and ID them individually.

2 it does use a traditional VLF field but reads a film off that field where each frame will be an individual reading.

The coils must have something to do with this.. Its in the brochure too.

I thank you for your time and effort. I'll just have to wait for more technical details on this and if in fact Minelab makes the description any more bold/clear and less "vague" (to me...maybe not to others) in terms of just what they definately are trying to say it does or doesn't do...and see how it plays out. They might not even be saying what it sounds to me like they are saying, so I don't even want to say what they are saying...Or criticize it because I personally don't know what they are saying. Boy, that's a lot of saying "saying"...Just saying. :biggrin:

I just don't know how to read exactly the "for sure" ability they are driving at here. Still could go either way *for me* in how that dual target ID works. I'm sure some of you have no doubt what they mean, but the wording to me could imply that it's either an outstanding new ability (and there is no doubt it would be if it does see two targets at once and displays them) or just a second ID referencing the previous target the coil saw before moving on. Even if it's just that it still could be a handy display feature to have. I don't know what to believe....Yet. So I'll wait and read and see.

I just keep thinking back to one detector companies commercials on TV in which they said "you see what the target is on the screen before you dig so you know it's treasure", or words to that effect. Of course we all know what the reality of that is.

Thanks again, as I don't want to post any more on the subject as I already made my questions as clear as I can and obviously have already been too redudant in laying that out. I'll wait and read and see what gives. Thanks again, and didn't mean to be any kind of trouble about it so thanks for putting up with me.
 
If a picture truly is worth a thousand words, maybe these pics will help explain "multiple targets simultaneously. Excuse the sunlight reflection. I was in a hurry and didn't make proper preparations to reduce the glare. Also note the "trail" is HUGE due to multiple sweeps in Target Trace Pinpoint.

Nice.

In the top pic it is difficult to see the lowest marker wich is a red rectangle but its there.

It did split the two objects and ID d them correctly.
 
Thanks for doing that. Here comes the "but wait", sorry...But wait...You can get the same coin/nail back and fourth response as you wiggle over a coin masked that way with just about any detector using a DD coil. I've done that exact same test with a nail laid just like that over the coin and wrote a little net "article" (if you want to call it that) with pictures on my findings of the iron (or other trash) in terms of how badly they are masking the coin by being laid out in various forms of physical relation to each other. Man, long sentence. Sorry. That form of masking using a nail laid directly on top of the coin is actually one of the easiest to overcome, in particular if you swing in a parallel orientation to the nail with a DD detection line.

As the DD detection line is to the side of the nail (parallel to it will give the easiest response for this test) it's seeing the coin, and as you move the coil the DD detection line moves off the coin and up and over top of the nail and then sees it, thus the coin/nail response over and over as you wiggle. I've done the same thing on my Minelab, but of course my machine will be going iron/coin/iron/coin back and fourth instead of seeing both at once on the screen. It could still mean it's simply a "history" of the last target seen along with the present one.

Sorry, once again I find myself covering the same material all over again so I'll shut my mouth and wait like I promised for more details from Minelab. I REALLY don't want to be any more of a bother than I already have been, so once again I apologize for being such a stick in the mud here and thanks for putting up with me. At this point in time I feel like a dog nipping at some body's ankle and I know I don't like it when that's done to me, so thanks for your patience.
 
Okay...here is how I replicated this test with my Omega using its 5" DD coil. Sens @ half maximum...iron disc'd out. Coil 4" above quarter/nickel @ 2" apart like Digger's example. Coil sweep east-west/west-east.....no accurate separation of audio/VDI. Coil sweep north-south/south-north the quarter/nickel easily separated with 100% correct audio/VDI...100% of the time.
Now if the CTX is able to 100% identify these two coins whether sweeping east-west/west-east & north-south/south-north at 4" coil height or deeper, then I think the CTX Trace has something valuable to offer.
My other question. Can the larger CTX stock coil trace this quarter/nickel 2" apart example, or only the 6" coil ?
 
The coils all provide the same Target Trace information. I just took the pic with the one I had on at the time. HH Randy

Can the CTX do the above?
 
I took two coins back outside and placed them perpendicular to the sweep path. In other words, both coins will pass under the "center bar" of the coil at the same time.

When sweeping the coil over both targets lined up one above the other, both targets will provide Target Trace imaging on the Smartscreen. Without stacking them, one of them will always be closer to the center "hot spot" than the other. (hot spot is my term, not Minelab's) The audio response tone is determined by the coin closest to the hot spot.. If your closer to being centered on the nickel, you'll hear the tone I have programmed for nickels. If you had dropped down 1/4 of an inch, you would hear the audio response that I had programmed for zinc pennies. With that in mind, while sweeping the coil, when you move it slightly "heel to toe", you can alternate which coin is closest to the "hot spot".

In this picture, I had isolated the nickel and continued to sweep the coil, sliding it down toward the penny.
[attachment 232768 nickelheadedtowardpenny.JPG]

After identifying the penny,I continued to sweep back and forth and slightly moved the coil back up toward the nickel
[attachment 232769 pennytonickel.JPG]

By activating Target Trace Pinpoint, colored imaging will intensify as you pass back and forth over both targets, and remain on the screen until the Pinpoint trigger is released.

Sorry for the poor pictures. It's getting dark and I was really trying to get this done tonight.

Digger...first off...thanks for the extra effort to answer my question.

The Omega will 100% separately identify targets when centerline of it's 5" coil is positioned as shown in your last set of 6" CTX pics. In that position I used the same sweep methods you did. However, as I said, if the coil centerline is direction is reversed, then the Omega doesn't correctly identify the separate coins.
This is not to beat a dead horse or try to put the CTX in a bad light. What I want to know is if the Trace technology is offering a far improved function of identifying co-located targets over what is already possible in other machines.
Can the CTX correctly separate & identify the two targets in both east-west/west-east & north-south/south-north coil sweep directions. The Omega can do it in one direction only. Does this also hold true for the CTX.
