Long ago, a company manufactured an add on limiter. It was a passive device (no battery needed) and plugged in between your 'phones and the detector. Very small, and it worked. Anyone remember who made this thing Yeah, I know a battery powered one was also available, but no longer. Any data appreciated.
are you talking about the depth master devices? i bought one for my 1260 fisher and it worked great. also had a set of headphones with the depth master built into them. still have the headphones but think they have a bad wire someplace cause they don't work like they should.............roger
Yes roger that sounds like the name.The device i had was a small metal tube shape that plugged into the metal detector then you plugged the headphones into it.I myself have tried to locate this device because it worked for me so well in the late 80's early 90's.It did not use a battery,which was amazing to me.The device would amplify weak signals and tone down loud signals like a shallow soda can.Man if a company would make these again they would sell like hot cakes.Hmmm.
Gees! I thought I updated this long ago. Here goes. I tracked this down and bought one. I really couldn't tell it did anything. So, I grabbed my trusty old Fluke DMM and measured the device. Nearest I could tell "Stereo A and Stereo B" were shorted together. I found infinite impedance between audio high and the shell. Next I got out my Huntron Tracker (a simple curve tracer) and repeated the test. I found no diode junctions, no capacitances or resistances from from any point to any point. Now if I was the suspicious type I'd think this was a simple 1/4 inch stereo to mono adaptor that had been relabeled. Now if you really look at closely, there is really no room in the thing for anything. It couldn't be much. These were my observations and opinions and were not intended to cast any bad vibs at the builder or designer of this product. There you are.
Yeah, I know a battery powered one was also available, but no longer. Any data appreciated.
