It is showing the coin but I only hear the iron

[JimmyCT]

Randy,

Thank you for your help and insight. - HH - Jim

I think we'd agree that rejection doesn't really reject the target. It is still detected. We just don't hear an audio response for it. What it does provide is a null or "lack of tone" on targets whose properties have been set to reject. And I think we would also agree that targets whose values have been set to accept will provide an audio response. In the screen shots, it appears to me that the search mode they are using has little or no discrimination. As such, the iron target will provide an audio response because it is an accepted target. I would think if they had been running with enough discrimination that the iron was "rejected" the audio response for it would have been silenced and the audio response for the coin might have been heard. Just a suggestion for those willing to listen. JMHO HH Randy

For several years, I've been using minimal discrimination on all my detectors. I was of the mindset that the more I heard, the better my odds of making good finds. But I have to say, the additional functionality of this detector has put that theory to bed for me. When you can implement Ferrous - Coin separation, Combined Tone profile and get heat trails on Detect and Pinpoint, I've been using more discrimination than I've had turned on in years. HH Randy

And with the push of a button, you can always hit the detect button to switch the discriminating pattern

For those of you that know me here on findmall, you know I do not like the complex. I like the turn on and go machines. However, what has really peaked my interest with the CTX 3030 is this new "heat seeking" technology to see all under the coil (whether it chirps in my headphones or not) This is a super improvement in metal detectors! Why? I have hearing loss on the top end (High frequencies) so what I may not be able to hear or hear and not pick up accurately, I will be able to see on the screen and have a visual. Watching a screen may slow me down but for those of us that are hearing impaired, I feel this machine will be able to help those of us with limitations to continue & enjoy the hobby of metal detecting. - Jim

Sounds like this might be a big help for you and others in your situation. This machine IMO is putting more emphasis on using the display. The information is in the display not just the audio. Some just want to dismiss this outright and are hoping that this is all smoke and mirrors so they can be first in line to say "I told you so". Its sad but true. The best part is not one has been sold, yet!

It would be very exciting if it does work but what I am worried about is that the detector is just doing what an etrac does now but keeps any location the cursor moves as a target instead of releasing it. What I mean is, and anyone who owns an etrac or explorer should have seen this, I have gone across iron targets with the etrac that bounced from the lower right to the silver range. when you take your time and rotate around the target with the machine a sure sign that it is iron is that at certain angles the machine will hit a much higher of the percentage times down in the lower right with an occasional bounce into the silver range. When it is a deep silver it will be more bouncy and a higher percentage of hits will come in the silver range. This is kinda hard to understand if you have not experienced it with those machines but for the people who go to hunted out places and pluck out the deep silver they will get what I am saying. So with that said if all this machine is doing is keeping both locations on the screen of that bouncy iron target then it will look a lot like what we are seing on the ctx screen. I will wait to see for myself on this one, and I am sure I will dig plenty of iron to do it. I am planning on getting one either way, the water proof ability, wireless and gps are enough for me to want one even if this machine is equal to an etrac in hunting capability, if it exceeds an etrac all the better.

i am not technical but as i see it you are right in that the law of physics makes it so a good target hidden under iron is masked and so will not give an audible sound but of course you will still pick up audibly all the other targets as other detectors will
now as you hear the iron grunt you either have to ignore it or investigate it which you can do with the screen this is the new technology
if you dont think that is interesting then not alot of point getting this machine because that is the advanced technology you are paying for and for me this is what i am excited about HAPPY HUNTING ao all of you

the "law of physics" gets quoted alot it seems, does anyone with a real physics background back up whats being said in this thread? Does the "law of physics" really state what is often quoted here and if so is it an absolute?

i didn't see much for a split second maybe but then it didnt show both objects at the end of the video and who's going to constantly look at a screen when detecting in my opinion this has no better separation or depth then my etrac and yes i can afford to buy the ctx3030 but i just dont see anything new for me to buy this detector i though minelabs next machine would be way more advanced but this is just an etrac with a new cover just my opinion

 

[Digger]

this is just an etrac with a new cover just my opinion

Opinions vary.
I'd have to think if you took the time to look through the videos and manual, you'd see this is a giant leap beyond the E-TRAC. So much more useful functionality. But, that is just my opinion. And as I said, opinions vary. HH Randy

Neil,

Ferrous metal disrupts the vlf electromagnetic field. This disruption will cover 'X' amount of area. The shape of this disruption field is determined by shape/density of ferrous item. A non-ferrous item within this disruption field will either not be detected or partially detected depending on how much intensity of the ferrous disruption field it is subjected to. Given a strong enough ferrous disruption field that overwhelms the non-ferrous' disruption field, no vlf detector in the world is ever going to detect the non-ferrous. That is a law of electromagnetic physics if one wishes to call it that.
How a machine is engineered to interpret these fields is the key. Some units are designed to null on a ferrous target at a given ferrous field disruption strength level and this includes anything within its field. Other units are more open to the same signal interpretation, and will ID targets by combining/seperating the ferrous/non-ferrous ID's. But as said, if the ferrous field is strong enough, no VLF technology will allow for detection of a non-ferrous item in its field of disruption.
Coil design/hardware/software enhancements can make a better performing machine as we all know. But there is the 'Wall' where VLF technology simply cannot penetrate through a ferrous signal of a particular strength. This is the 'Law' that is being referred to.

And T-Digger if you were to throw in a halo effect from real ground effects with some wet airy soil and a few hot rocks then you would put everyone back on the fence,uh oh. LOL!!!!!!! Mine is on it's way.

 

[Digger]

no vlf detector in the world is ever going to detect the non-ferrous.

VLF technology simply cannot penetrate through a ferrous signal of a particular strength

VLF is typically considered to range from 3 kHz - 50 kHz. Some even make the high at 30 kHz. The FBS2 technology of the CTX 3030 operates within 1.5 kHz to 100 kHz. Obviously, not the frequency range that is considered VLF. Thanks for the post. HH Randy

Will it still do that when a ground matrix is introduced or rather in the dirt?
I'm not totally convinced.

 

[Aaron]

Nice explanation Terra, you get that from Tom?

I agree, and that's exactly what I was thinking too, is who's gonna be looking at the screen especially in a real trashy area? All these above ground tests need to be taken w a grain of salt.
And incase I'm being accused of being negative, well....mine is paid in advance and will have it on 6/2

So well all see....

 

[Aaron]

Heat seeking?
Really?
Didn't know coins generated any...
Clever.

 

[Aaron]

n/t

 

[Aaron]

You'd be swinging that coil REALLY slow in hi trash/iron, watching the screen at the same time.

Its simply something people have taken to calling the target trace screen. Due to the coloring of it I would assume.

For people who continually say "who's gonna be looking at the screen" what else are you looking at? The coil is in front of you, the screen is in font of you and you're looking ahead and down at the same time. This puts the coil and screen in your field of vision and even if you're not focused on the screen you can still see it. I would assume the color screen would aid in this greatly. I mean are people walking around with their eyes closed or in a complete fog?? A blind fold maybe?? LOL
