Hi. I have a Bounty Hunter Outlaw TR/BFO model which has a problem. The unit appears to work ok with the 6" coil. I am able to properly tune it in both TR or BFO mode and use the discriminator switch as well. It detects well with this coil. However, when I attach the 6" x 12" triple coil, The detector will give a continuous tone and I am unable to eliminate it by tuning with the vernier knob. I'm aware that this triple coil has ground balancing ability. This coil also has a long crack on the plastic underside, but I can't tell if there is internal damage, nor do I know how to test it. I don't see a problem with the connectors and don't really know where to start looking inside detector box itself. Does anyone have a suggestion and/or schematic? I am very capable technical -wise. Thanks in advance.

Hello . Your first step is get a decent ohm meter and check the resistance readings on your good 6 inch coil , write it down on paper . Then check resistance readings on the 6 inch by 12 inch coil . If there is a big difference in measurements then the main problem is with the 6 by 12 coil . I have not seen an Outlaw BFO schematic ever posted on the internet . Another option is to contact 1st Texas to see if they can send you a copy of the schematic .
Once and a while you still see a Outlaw Detector with a 6 by 12 coil for sale on ebay   . Let us know your progress .

HH....... Great.....Eugene

Yep!  Sounds like a coil problem.    Have you open the coil connector to see if a wire came loose?

Hi. Yes, I have a VOM and can test for resistance. Good idea. I assume that with the 6" coil I will have fewer measurements to make against ground, than with the 6x12 triple coil. The triple coil has three coils and so I assume that there will be at least two more measurements, one for each additional coil. I guess looking at both coil connectors partly disassembled will give me the clues. I've seen a schematic for a Bounty Hunter 840, which is a TR VLF unit, not a hybrid unit like this one. I've searched extensively on the web for a schematic for the Outlaw TR/BFO so far without any luck. I'll contact 1st Texas as you suggest.

I haven't opened the connector yet, but have noticed that the continuous tone happens -when the coil is plugged in- and the unit is then turned on. When there is no coil connected to the box, there will be no tone whatsoever when the unit is turned on.

Any way you can post a photo of the detector, and Full Name/Model number?

The connectors look good on both coils and ohmmeter readings are from 5 - 7 ohms per connection on both coils. The 6" coil has ground + 1 connection, the 6"x12" triple coil has ground + two connections

With out a photo, I have no clue.

The coil you say is triple, I guess was two for the TR and One for the BFO.

Hi. Here are photos of the Bounty Hunter Outlaw TR / BFO Model. It comes with two coils. One is a 6" single coil and the other is called a "triple coil" 6" x 12". The connectors have 4 pins. On the 6" coil it has one pin connected plus ground, and the triple has two pins connected plus ground. It isn't clear to me why the triple coil has two pins -not- three pins connected. The readings on all the pins of both connectors are 5 - 7 ohms.

It appears to me that TR and BFO function on both size coils. The triple coil is used for ground balance capability.

It's entirely possible that the second coil was made for a different machine and you will spin your wheels endlessly trying to make it work with yours. As Eugene suggested,you should contact the manufacturer for advice before proceeding.

The triple coil is NOT for ground balance but for an Induction Balance detector, which your model does not support. I believe your bundled purchase was mis-bundled. If you can find out which machine that coil is for, you might be able to sell it.

Hi. Yes, the triple coil is for induction balance. That is my mistake of using the wrong term. That's what it says on the coil. The instructions of this unit, however, -does say- that the 6" x 12" is designed for the TR/BFO model. This model comes with two coils. See the attached vintage ad from Bounty Hunter. -Thanks
