Bounty Hunter

[nonkapo]

You welcome. Skippy's help in all my BH, Fisher etc Texas related threads have being always invaluable.

[ivconic]

Thank You very much!
But don't bother, because i have now all i wanted from infos.
Cheers!

Добър дан Ivconic. Here is what i have for the quicksilver EX - https://www.geotech1.com/forums/show...board-pictures However if you need more detailed photos of the boards, let me know. I'll be back from vacation 1st of July and than planning to sell that machine.

Here is the thread I mentioned with Fisher F2 schematics:
https://www.geotech1.com/forums/show...5-F2-Schematic

[Skippy]

Yes, there is an internal capacitor. The TX inductance is 2.4 mH, and there is a parallel pair of ( 220 nF + 22 nF or 20 nF ) = 240 nF across it. I'm not sure of the capacitor type, the 22 nF was a common polyester type, the 'dipped mylar' that are usually green colour. The 220n may also be polyester, but polypropylene may be a possibility, for temperature stability?
RX inductance is also 2.4 mH, with no added C,R,etc. RX resistance is quite low, 2 Ohms.

I will look for the details later. I did download the schematic. It's reverse-engineered, so it has a few errors.

Hmmm ... perhaps it would've been helpful if you had explained why you want this info , in your first post.

The Fisher F2 schematic is on the forum somewhere. That uses the 6.6 kHz BH coils, but adds an extra 47 nF of capacitance across the coil ( which has 240 nF internally ) dropping the operating freq down to 6.0 kHz.

That is something. Thanks!
Are you sure that BH coil is having internal capacitor?

I don't do that, i love them ALL!
I just ask for the schematic of any BH model younger than 30-40 years.
I have here brand new 10" concentric coil.
It has specs that don't suit my present design.
So i wanted to see original circuit and (if possible) to adapt my frontends to suit the coil.
All the BH schematics that i have (few) are dating from 30-40 years back... no use from them.

I think you should add the Bounty Hunter Junior to your list. It is also sold by other names, including the BH Handyman, and is also branded Discovery, I think.
It's a kids detector, that actually works. I have no idea about the search coil, it's 6 inches, and may be unique to that machine. But it operates at the same 6.6kHz that many other low-end BH's use, so there may be coil compatibility.
It's cheap, and probably has no microprocessors in it.
And Dave Johnson thinks it's good.

There are some lookalike machines in the Chinese MD-xxxx style, but whether they are good clones or junk in a nice box I don't know.

The Tracker4 has been in production so long there are two different PCB layouts, a leaded and an SMD.

yes skippy, the BH junior is quite competent for what it is, i suppose it shows that the bounty hunter base design is good.
i know lots of US detectorists swear by BH gear, its such a shame that in europe they have a cheapo "1st detector" image, i think that is a british and european failing we confuse cheapness with value for money sometimes.
whenever i have used BH detectors i have been impressed, and the only problems with them are other peoples perceptions of them, and actually finding a UK supplier that stocks the whole range.

Are there any chances some of you forum members to contribute here by sharing the schematic that you may have, from some of those from the list?
If no schematic; clear straight macro photo of all both pcb sides will help a lot too.
I would try to retrace them in such case.
If you have it; share it!
If you have it and too lazy or don't want to share it... than stick it right up into your... simple as that.
