Bounty Hunter VLF/SPD Problem

[Jimi]

Hi Folks, a friend brought over a Bounty Hunter VLF/SPD detector with some problems. Thought I would put them out to the list and see if anyone had any sugestions.


Symtoms: Apply power and you get "full" deflection on the meter and no audio. This is in any mode. Have searched for a schematic with no luck, also don't have an operators manual for it. Anyone ever run into this problem befor? Where to look? Also sugested repair?


Also any usfull mods to this unit, IE depth or sensativity? Would appriciate any sugestions on this one. Great forum Mr. Carl, glad you brought it up.


JIMI in NM.


Ps, He has a couple of "Whites detectors with the same exact problem, any thoughts on these.

What model is it? I have an RB5 (Red Baron jr) for which I have traced out the circuit schematic and the RB7 is practically identical. As soon as I redraw it in a CAD program I will post it on the web page.


Keith Wills does detector repair, I have a link to his web page in the metal detector section. He once told me that a common problem with the RB's is the power supply circuit. There is a dual opamp that is set up as a regulator for both rails so this might be your problem if one side is out.

Have not tried any mods yet but they should be fairly simple.

It Is a Red Baron TR/SPD discriminator


Q; Is this a PI unit?

He has a Coinmaster Geb and Geb Disc. Both with the same problem,


I have 2 old Golmaster's The TR versions and a 5000 d, with the same problem, Just got through moving and want to start on these, About time to start making some headway.


Also any mods for the Gold masters?

No, the RB's were VLF motion discriminators. I don't recall that BH ever made a PI detector.

Again, I would start with the voltage regulators. At the very least the battery check should work. I have to wonder whether these units are worth a lot of time or money to get them repaired. I've been messing with some of this old stuff just to figure out how they work, but I would not bother to take them into the field. I am always looking for junkers to reverse engineer so if you want to get rid of anything please let me know.


>Also any mods for the Gold masters?


Sorry, not too familiar with these.

Thanks a lot

Jimi, pls, can you send me a copy of RB5 Schematic. I´ve one RB3 with problems, and I know the RB5 are one upgraded copy of RB3.
Can send me to [email protected] if you like.
Thanks

Hopefully you noticed that the message you're replying to is 13 years old.

That´s the magic of forum. I can see over the time to ask some help to my old model.

there was only RB7 sketch schematic with some PCB photos I see and kept from this forum. that's all.

I maintain a website with manuals and some info on old Bounty Hunter models:

Sorry, I don't repair them or offer schematics but I get many requests. Do a search on Geotech for any schematics that may be available. Repair requests are usually sent to http://www.brokendetectors.com

Hi Peeps,Well i have just joined cause funny enough i have just recently bought my first metal detector from a porn shop in australia sydney and it happens to be a Red Barron vlf spd IN PERFECT CONDITION DONT THINK ITS BEEN USED MORE THAN ONCE out of the three search coils supplied only one has a few scratches on it,the others are new!Except i brought it home knowning it had no battery pac as store guy told me he could find one to suit lol.Anyway i went to tandys and got two of 8 x AA Battery holder and sixteen new batteries.I really dont think my detector has been played with inside or out as the inside of box is completly clean with no smelll of burn outs,so i put black to black and red to red and followed colors on both pacs and i get the same ,no audio and full deflection on meter please can anybody help,i can supply pics and origal broucher,i got a carry case as well {original}with the foam inserts, head phones, three different size search coils if anybody want to see or needs any info i CAN supplies ,please hurry i am dyeing to use this thing :] thanks in advance
