AlgoForce And Target ID

[phrunt]

One of the things that made me just have to have the Algoforce was the promise of Target ID's on it, I didn't think they'd be near as good as they in fact are.  It's taken me by surprise and I think people will find it useful in many ways.

The one thing so far that's standing out is shotgun pellets, every pellet I've tried and I noticed this in the gold field the other day the pellets ID at 00, and the gold I found both bit were in the numbers, not 00.  So I've now tried a few more pellets, and a lot more gold and almost all of the gold gives a numbered ID and every pellet is giving me a 00, I think the sphere shape of the pellets is causing them to ID really low on 00.  There is likely some pellets that will ID in the numbers and there is certainly some gold that ID's at 00, for example the smallest piece of my test bits was coming up as a 00, the one pictured below, it's smaller than the pellets.

I thought I'd film a little demonstration video of this, along with showing some coin and junk target ID's on it to give people an idea of how it all works and the ID's it is showing.

Again, my usual raw video style, fumbles, mumbles, mistakes and all. 🙂

Then I went out into my yard where I have a couple of NZ $1 or $2 coins buried, I think now using the Algoforce on them and its wonderful Target ID's they must be $2 coins, the Manticore is a bit wild on them and I could have messed around, tweaked it and done whatever else to try get it a bit better but the point of the demonstration isn't the Manticore, so I just did a ground balance, and noise cancel and had the sensitivity low enough the EMI wasn't causing too much havoc.    The Nox 800 is more stable and detects these coins with a more accurate target ID of 21/22 on the easier one, and a bit bouncy on the deeper one but still a repeatable 21/22, the reason I'm now more confident they're $2 coins is the Algoforce seems to get a different ID for the two coins being different sizes, whereas on the Nox they both come in at 21/22 bouncing between the two, even in an air test.  It's just been so many years since I put them in the ground I've forgotten, and the fact the Nox Id's them both the same I didn't overly care when burying them which of the two they were.

So here is a little demonstration video of the Manticore and the Algoforce on these two buried coins.

I had a fumble in the middle of the video leaving the Algoforce in pinpoint mode and for some reason my brain fart had me pressing re-tune to quiet the pinpoint mode down and tune out the target rather than exiting out of pinpoint mode and checking the target, I realize and fix it up but it wastes a few seconds of the video, either way, I wasn't going to bother filming it again or editing it to get rid of that so you'll have to deal with it 🙂

 

I hope this helps understand its target ID's better for those interested.  A change they could make in a new firmware update I think is a separate volume control for the pinpoint mode, that'd be a nice thing to have so I will suggest that to them.  (I contacted Algoforce about having an Independant pinpoint volume and it is coming in a new firmware update very soon)

Force 1500 is surprisingly exactly the ID on the coins ...Simon.
.And as for the pellets and their *VDI 00, I think it is confirmed that the PI detector really sees the lead alloy weaker than gold nuggets of a similar size, because these have a significantly higher VDI 12 number......

even the VDI for various lead bullets are somewhere where I would expect it...👍

Interesting how much more it likes gold then lead...thanks for posting Simon. This is good stuff.

Thanks for showing how stable the TIDs are phrunt, I really like your UN edited videos

Great stuff Simon. Can I ask if you notice any difference in signal, between the 00 lead and the 00 gold when not in pinpoint?

As you pointed out, some small gold will read the same as lead when pinpointed, would be interesting to see if there were any other indicators to tell the difference. Target Id does seem to work a treat though.

No, I don't think someone would be able to distinguish the difference when the gold falls into the same ID range.  One thing is for sure, next time I'm prospecting if I get targets that go above 00, I'll be getting more excited of something other than a pellet. 🙂

Don't forget the large NZ targets.

Found in NZ look at the date.

Simon thanks for all your work. All great info. I have two questions on the Algo. Does the ID change or stay the same if the coins are turned vertical vs flat? While detecting do the soil mineralization numbers jump quickly then return when sweeping the coil over hot rocks?

Good questions, I had to check both then to see, a coin on absolute edge dropped from 66 ID down to 15, if it's on a slight slope not on total edge the number is correct, as long as it has some of the coin facing it and not completely on edge, I might get a video tomorrow to explain better.

The Hot rock thing, the mineralisation bars move up and so does the centre number as the hot rock is under the coil, move the coil away and the mineralisation bars revert back to normal, they start to go down again about 2 seconds after the hot rock is removed, and are back to normal within about 5 seconds if that.  Swinging over a hot rock it won't have time for the bars to creep right up, it's going to be a slight rise in the meter, and that means it will recover quicker.  The way I did it here was sitting a hot rock on the coil, removing it and seeing how quickly it recovers, just passing over is quicker as it doesn't get as much of a response from the hot rock as it sitting still on top of it so the recovery of the meters is faster as they don't rise as much. I hope that makes sense.

Yes makes sense Simon. Thanks again for your time.
