My new excal II doing air test video gold versus pull tab

[TheDualFieldBandit]

I'm trying to learn the different sounds of the excal II. Gold versus pull tabs and such? One thing got me a little nerved up is this high end ring sound like pull tab!!! The first minute of the video isn't much but it gets more interesting as it goes. Give me some feedback as to your experiences with the sounds and tones of the excal II. I'm just used to my Dual Field sometime I'll do a air test video on that unit and show the differences between gold and pull tabs seems to be more reliable in telling them apart within six inches of the coil then the differences start to fade a bit.

When you figure it out make another video, write a book and you will become a multi millionaire Unfortunately it isn't going to happen

I see an issue with your test. You get your first feed back from a target being the original signal or target hit from the machine. You are grading the machine on that criteria alone. You should be listening to the feedback "after" the original target tone. It will be a medium to medium low hum/tone. Not as low as the iron growl, not as high as a dime or penny either. Now that really depends on the content of the gold also. You have to realize, most good quality gold rings especially with diamonds, the stone is held in place with almost always platinum prongs. You will read that to in a mix of the metals. Anyway the feedback is the tell tale signature you should be listening for not as your test is showing. Give it a try, it's not a beep and dig machine................However to dig every target is the way to find more gold. Just ignore the iron not unless it has a slight crackle to it then it can be a good target also.

GREAT VIDIO, in the gold it seems to be lagging behind and rubbery exept the ring that had the ROUND top that is key because not only does the composition play a part but the SHAPE and the top of the ring was round and flat so you got the higher tone, the crupled up foil relly sounded close, I will be watching this vidio many more times and may make one similar to show some rings i know a ring laying flat give a far diffrent signal than one on edge, thanks for posting love the vidio

I might add, having owned 4 Sovereigns, including the first back in 1994, don't trust air tests! I/you rarely hunt anything in the air anyway. Learn it in the ground through experience; that's all that really counts.
Now I am off of my soapbox. Enjoy your machine- it's great.

air tests dont find the good stuff, just get out and swing and learn the tones from doing allot of hunting..learn what its trying to tell you,then youll find the goodies, of course then you need to learn how to read a beach to..

excals are not cherry pickers.......basically the main function as i see it of disc on the excal is to greatly lessen the amount of iron targets you will dig....if you run very low discrimination you will pick up almost all non-ferrous targets..... the 4400 dollar ring and the pulltab both sound like targets i will chase.... with a little practice you will be able to predict most common coins prior to digging.... all other targets are a mystery until dug and thats half the fun ,trying to guess whats gonna come out next....happy hunting.....

I have dug hundreds of rings now and ones things for sure If it sounds like anthing form a piece of Foil to a Quarter. Dig it..... every thing stated by the guys above is true you have several varriable that will change the tone of a gold ring form the metals mixed with the gold,2 tone gold rings,diffrent shapes as u saw on one of your rings and diffrent ground matrix.
Good luck. I liked the video. One thing i have learned and so far can gues them pretty well is most pop tops give a double beep in one of the 4 directions. Gold will not its always solid all the way through unless its a chain with a cross or odd pendent.

Thanks for all your comments! This a beep and dig unit so far. I went to Hampton Beach yesterday to try out in the wet salt matrix's found a 18k band it sounded a high tone like a penny? Seven days owning it. It's paid for it's self with a elven ring tally in those seven days. HH

Bandit, is your objective, from this video, to show that there might be a learnable difference between aluminum (or specifically only aluminum pulltabs?) and gold? If so, I'm going to have to agree with Erik, that it's not going to happen. Oh sure: you might discern a difference between all the different targets in your sample set of various rings and aluminum there. Sure. But SO TOO will there be differences between each gold ring, to all other gold rings. And so too will there be infinate differences between various types of pulltabs. Some have the beaver tail pulled off, others have the beaver tail bent half way. Others have the beaver tail bent fully flat with it, etc... Various soda manufacturers have various sizes and densities and shapes of tabs. And of course, foil wads and can slaw will come in infinate sites and shapes, right? So too is gold jewelry formed in infinate sizes and shapes.

I know it's tempting to try to think we can learn the difference (because no one wants to dig junk), but all you will ever do, is learn the sound difference between two items you happen to be holding, at that exact time, in your hand. Once you get out in the field, ...... the harsh realities kick in.

About the only thing you can do, is ring enhancement programs. That's not telling gold apart from aluminum though. It's only telling you what items might be commonly recurring aluminum junk items. Like square tabs of the same brand soda (assuming not bent, split, tilted, etc...) would read about the same. Same for like-brand round tabs, you can start to mentally pass *just* that one signature, assuming it's the same size/shape tab, etc... But be assured, by doing this, you WILL miss gold that fell into that range/tone/sound, and you WILL dig junk.

You might want to read the thread from a week or so ago, where the same subject was talked about in regard to the Tony Diana CD.

Thanks you are right! Need to dig everything! I was told you can tell the differences between the two but you really can't is what I've found out! Thanks again!

 

[Big Boys Hobbies]

Great video and post! lots of good info here!

It seems like if the conclusion is to dig everything then other good detectors that go deep in bad ground and discriminate iron well would do about as good as the Sov. It makes me think of using a PI detector and a magnet to separate the iron. It would be slower but the detector might cost a lot less. But I'm not about to give up my GT.

Bandit, you say:

"I was told you can tell the differences between the two "

Who told you this? Next time you see this person, try this on them: Take them down to the nearest blighted urban inner city junky park. Turn them loose and see how much gold they can dig, and how much aluminum they leave behind. I have a hunch it will boil down to random odds, by the time they are done trying to show you. See how long they stick to those claims

 

[Tom_in_CA]

Well, by saying that since a person can't tell the difference between aluminum and gold, that "they might as well get a pulse machine then", does not logically follow. Just because machines can't tell the difference between aluminum and gold, doesn't mean that we all still don't want to reject iron (certain beach or nugget hunting venues aside, for the sake of discussion here). The extra bit of depth a pulse machine provides, is in no way worth the headaches they would give you at the typical park or relicky site. You would go insane trying to use one in some junky urban demolition site, park, etc.... You simply must have at least iron disc. And I don't see how a magnet is going to help. How is that supposed to rid the ground of buried iron before you start?

Also, even though a person might intend to dig all above iron, having the TID is still a lot of fun though. You can (if you wanted to, and if targets were prolific enough on the beach after a good erosion episode reveals un-ending targets) you could elect to pass all high conductors (which are 99% of the time going to be penny/dime/quarters, right?). And all sorts of other benefits, even in places where you think you're going to "dig all", nothing can compare to the chills down your spine, when you get that perfect penny/dime signal under a side-walk demo, where the soil hasn't seen the light of day for 120 yrs Contrast to a beep and dig machine, where every single target sounds the same.
