From what I can gather, higher frequency VLF detectors are more suited for smaller gold but ground mineralisation may be something to factor in. Would there be a “better” frequency for nuggets 1 gram and above in heavy ground?
I’m not too concerned if I miss sub gram nuggets if there is a better suited frequency.
The old Garrett Groundhog circuitry was legendary in this country…..I think it was around the 15 kHz mark. Is this frequency range a good starting point or do I need to consider other things such as better ground balancing capabilities or Garrett’s extra coil voltage.
My Minelab PI units will be mainstay detectors but as mentioned in another post, I have ground littered in man made iron junk and the ground mineralisation is severe. There are plenty of nuggets in the 1 gram to 5 gram range (maybe bigger) but the iron signals are as dense as 5 per square metre 🤬
Thanks for any ideas.
After the good new I realized when tested a few days ago my machine after It drowned and I've succesfully reanimated It....
Now the horrible gasket Is fighting to stay out of the housing against any kind of attempt😒.
So I'm in the middle of a headache manutention session with scarce results.
That's the Mood guys😑
Manufacturers Making Updatable Detectors Should Imo Allow Models To Accommodate Multiple Software VersionsBy Tnsharpshooter
Don’t know any other better subforum to place this.
When manufacturers design make sure platform can allow at least 2 software versions or at the very least allow what I call both newer version update (whole) and a older subset (portion of older version) to be used.
Makes testing easier if and when a newer version is designed and requires pre release testing in the field for validation. Would allow users after version release to use different versions and gain first hand feedback of the benefits or lack thereof of different versions or version subset(s). Case in point. Notice Minelab left old iron bias to be user selected when they released newer version with iron bias F2 option.
So in a nutshell this allows the detector versions ( or version subset) to be compared to the themselves in the field by the user.
Xp should have done this too. They should have designed Deus imo where at least 2 complete version allowed to be uploaded to unit.
Notice the later released Ace Apex. Garrett should have allowed on it too.
Don’t know what added production cost this would cause. Hopefully not much.
This was mentioned by geof_junk in another thread and had a little Google.

I don’t really understand the technical side of metal detectors. Does this have any application to current day detectors? Will it help cancel out ground noise more? Will the current crossing/not crossing the ‘bridge’ tell you something about what is under one of the receive coils.
Although I don’t understand it, I am amazed and a little in awe of those that do 👍
