A few pics for teasing purposes

I wonder what frequency those coils perform best at.

Like how the 18khz is the 'real performer' in the current coils, for lack of better words.

I wonder what would the equivalent frequency be for these coils. Hopefully the highest frequency again.

Dunno, but I believe the higher the frequency, the less depth you get. But also the smaller the gold it can detect.

Well a wire running from coil to shaft, no matter how well protected, it's thin and still vulnerable to damage at the pivot point. Imagine pushing that coil through dry scrub. A well placed sharp stick or thorn....goodnight!

Edit* And imagine working a closed vs open coil in the water...think about drag./edit*

At 400 bones it should come with a few coil protectors perhaps, eh?

And as far as weight, it's a 6x9....lmao! How light does it need to be beyond that.

Not practical for a solid coil with current battery charging setup. Easy to glue a solid piece of lite plastic to bottom of current coil cover.

Good question.

Open coils get hung up on rocks, stubble, etc.

If you're hunting very tiny gold items you're going to want to get maximum depth, and gold bearing ground is usually highly mineralized, which limits depth... if that coil is not scrubbing the ground you'd be leaving very valuable gold behind that's still within detection range.

That makes sense. I thought those covered coils were just old school. I actually have the original gold bug, but I've never thought about gold hunting here in Michigan and how one would swing the detector. I've sense watched a few videos and I get it now. Thanks.

Seems it would easily be doable if the French wanted to.


Sorry this is crude drawing done quickly in PS Touch on a tablet.

But something like my illustration. Nobody can say there isn't enough space in the coil...they have an open coil already. The contacts need not protrude as far as I've crudly illustrated. They may only need to protrude 1/4 inch with an enclosed recess to allow charging clip insertion.

Perhaps they had issues with high frequency coil in close proximity to a battery.

Ok, here we go. Some nice close-up shots of the new MI-6.

What can be other connector if connector at all?

Probably a vent hole for the lithium-polymer battery. I know my e-cigarette has one.
