XP deus coil modification

[smity]

Henrikas hello! You are doing a great and interesting work. Please make a measurement at the input of the operational amplifier (C3), the output of ТР1 and the seventh output amplifier. Interested gain coefficient. Thank you!

Smity... That not posible anymore. The PCB board is inside a plastic box and sealed. Sorry.

great post about the electronics of the XP coils.

It will help me in my repair job

Hi friends! There was a question about the correctness of my work, made the winding, measured the inductance all the same factory, but adequate response to the target is not! VDI shifted to the bottom, in some moments throws the coin into discrimination. As far as I understand I have shifted PHASES (do not respond video, as shown Henrikras ), please tell me how to change them, what a principled way

Hello, did someone traced coil pcb schematic?

I built a 5 1/2" for the Bandido

I used it as my main coil for about a year

finds rates was about the same as my 10" coil

You cover less physical distance. But the actual area detected isn't that much less. Most field here have a scattering of horse shoes and ploughshare. The best I can detect on our tiny hammered coins with any coil is a distance of half the coil diameter. So the larger coil spends more time being blinded.


Depth wise on smaller than a UK pre decimal 1/2" penny is identical. I have a very thin half penny buried in my lawn at 10. Its a tough target but is detectable with the 5 1/2" The larger coils does go deeper on larger target. So yes you might miss a bronze age axe. But you aren't wasting time digging aluminium cans at 20"

It can of all averages out. One big plus of a small coil one fields that have already been done is how much closer you can get to metal fields.


I see the stock coil for the new Garrett Apex has a width of 6"

i understand what you are saying, you are right. I ask for schematic because i want to further experiment with wireless detector systems.

this is all I have ever seen

I haven't look at all the 15 pages on xp detectors

Meanwhile for sure 100s of XP Deus are R.I.P. just because the coil battery died and
the users are NOT AT ALL interested to pay a lot of money for sending it somewhere
for replacement or try on their own to change this crap !!!

It was already a stupid idea in the first place to attach such a larger metal-object as a
battery so close to the coil togehter with PCB! *laugh*

So the only useful modification for these anyway to small XP coils is to
add some kind of battery-compartment for smaller outside chargeable
LiPo cells.
