Reading about precious metals I see that silver best responds to low numbers like 4kHz and gold to higher numbers like 40kHz.
My question is would using a single low frequency machine like an XP ORX for silver work better than the multi frequency machine that covers that low number while running the other numbers too?
Same question on the gold, at a high frequency.
You asked two very good questions.
I don’t post much here anymore.
I will try to answer your questions.
First. Can I take a 4 kHz single freq and locate on average as many copper snd silver coins per sweep, vs a good multi freq detector program? No.
Second can I take a single freq 40 kHz detector and find as many low conductors per sweep vs a good multi freq detector program? No.
I encourage you to go watch my channel, I actually do a load of comparison tests comparing mukti freq Deus 2 to single freq ops. What’s good about this is Deus 2 can be run in lot different single freq ops vs all other multi freq detectors out there. So it paints a real good picture imo.
Multi freq can give advantage on both nonferrous near iron and near lower conductors (in case of higher conductor).
Now single freq, using just one freq at atime will have its strengths and weaknesses. These weaknesses will be lot more vs mufti freq.
I posted a video the other day. And here’s what I said. Minelab May have slipped up not putting single freq ops on their FBS/FbS 2 units.
Why?
Because if they would have it would have been made apparent faster and moreso to the advantages of their multi frequency ops. Folks may have caught on faster to the multi freq thingy.
Remember the detecting situation has to exist for multi to shine over single freq. This goes for single freq used vs target swept as well masking be it caused by either or lower conductive trash or ferrous.
If all targets were sitting solo, would single freq still have equal or better advantage vs multi freq? No, not all the time.
Would depend on soil mineralization. And ID of deeper targets even in milder soil multi freq can have advantage.
Multi freq has higher potential to do better selective digging overall vs single freq.
You’ll notice many single freq detectors run on 13-15 kHz. This is not by accident. These give the best of all worlds generally. Vs using say a detector at 10kHz or less or a detector running 18 kHz or higher.
This all really goes to laws of averages for locating a find and even possibly getting more accurate ID (conductive level) of target.
Are multi freq the end all? Nope.
Are multi freq detectors perfect? Nope.
You get to hunt a site one time or spend one day.
A skilled user of multi freq (the right model) detectorist should have better odds of locating targets and doing more more select digging,
You mentioned ORX. I think it IDs like Deus 1. Meaning once a target gets so deep (yet still detectsble) it will ID in higher vdi range.
Example.
A 8 inch dime and a 8” nickel have a good chance of giving more or less same tone and more or less same ID.
If you sweep both the 8” deep nickel and dime with Deus 2 using multi freq nickel will ID around 64 and dime will ID around 91.
So ORX is not a good selective digging machine vs some of the multi freq out there. ORX can do well though as long as site has had no fill dirt, but when a user is digging deeper target (conductivity more unknown.
I hope these comments help you.
If you watch some of my videos you will hear me comment on the power of multi freq using Deus 2 and yes even the Manticore in tests.
The test I do elevated, they do show detector tendencies. If they didn’t I wouldn’t be doing.
I also add there are times when single freq will see nonferrous in test comparisons I do. But and a big but, lots of times there will be a coil height advantage above test or a coil (being able to be swept closer to iron) of nonferrous using multi frequency vs single freq. Plus there can even be a coil span advantage for detection using multi freq vs single freq. All this attributes of multi freq can give user advantage in the field (not knowing what user is sweeping coil over) to be able to locate more targets per sweeps made with coil.
Now not all multi freq detectors are created equal. Not even all multi freq programs on the same detector are created equal. A user must learn which program has which strengths and weaknesses. I have tested heavily Etrac, Equinox, Manticore made by Minelab, and Deus 2 made by Xp and Legend made by Nokta. I used all these detectors in the wild a lot as well. Legend has had update since my last testing. I sold it to a friend up the road from me. I gave my Equinox away to a stranger online via a drawing I did.
Cheers.
