But what do you want with this crazy wish
: "let this cannonball detector go" (leave it rest in peace =Ruhe) ??? Why I should? I'm detecting hundred other things, too!!! Larger areas, more stuff and deeper things - it's the complete package that counts! And the Jeohunter still could find little coins!I tell you what:
What we need is a detector that finds very small and very deep stuff and has ultra-lightweight coil. So far it doesn't exist so we either have to invent it or we have to live with the compromises.
Your dealers arguments only represent the aspect of finding very little stuff like gold-nuggets or small coins. And it's not fair to condemn the Jeohunter just because of this single point. If you wanna hunt for micro-gold nuggets get some extremly expensive Minelab with mini 5'' or 10cm coil. I have such small coil and I know how long it takes to search with this just a few squaremeters - and forget about deep stuff with such coils.
btw. you can ask ishtar hunter how good the little coil works with the Jeohunter - I don't have this 20x30cm coil but he has it and he can tell you how deep it detects (very) small stuff. This one also works well on beaches for the usual coin and ring hunting.
But for realistical treasure hunting the standard 45cm is perfect because it still can find usual coins at around 20cm depth but it covers a huge scan area and it even finds very deep stuff. The weight is a problem but it takes some amount of heavy copper for the coil for real depth power - this is simple electromagnetism law.
And it has no sense if you work with a small coil if you never will reach the region or depth where something is hidden! 45cm ist the minimum size for realistic and effective treasure hunting, everything else is for kids on small beaches or sand-boxes!

Hunting for goldnuggets is a special topic because most of the time they are extremly small or like sand grains. We would need a completly new technology that could detect grains and very deep stuff at the same time - this only would work with a combination of different coils which are connected in series or so. Or with cylindrical coils like those are used for wireless engery transfer. Best with some kind of reflector for power doubling!
I still wonder why it should not be possible using much higher frequencies! Bad ground penetration - yeah, maybe, but who cares if we raise the voltage?! Higher frequencies have much better resolution so they can find very small stuff and if the radiation is strong enough those will reach some good depths, too. And perhaps the at least 2 coils need to have some focus angle for centering the target. We may see...
