• Rotate the 'Tuner' know fully counter-clockwise until it stops. The audio might be very loud.

• Now, rotate the 'Tuner' control clockwise until the audio reduces to a Threshold setting and then Nulls to silence.

• Continue adjusting the 'Tuner' control clockwise until it starts to make a slight audio Threshold hum and continue to fully clockwise which should be loud.

• Then, adjust the 'Tuner' control back into the silent Null zone.

At this point you will know if your detector is working properly or not. If you adjust the Tuner control and find a 'Null' adjustment zone and can turn it clockwise or counterclockwise and adjust into an audio zone, then you have a Metal / Mineral Locator. All you have to do is determine which direction, left or right, you need to adjust from the Null to adjust to get a positive response from a Metal sample, such as a Clad Dime,


And this is why I posted it here. Thank you for the understandable guidance Monte. Only one thing, the tuning knob does not have a "stop". You can turn and turn to infinity. After I opened it up I understood why, the open fin type variable capacitor. If you keep turning, the fins simply disengage, then re-engage again if you keep turning the knob. But in reading your response I think I understand what you are saying. On the control panel there is an indicator line at 12 o'clock above the tuning knob. Perhaps aligning the knob indicator with that is where one should start, then adjust to the left or right depending on if you are seeking metal or mineral?

WM6- I will open the unit back up this afternoon and capture some good internal pictures.

Thanks again,,, Jason
