threshold question

[pax]

when hunting in disc do you hear deeper targets when threshold volume is high or low? I have yet to find an answer

just audible if it is too loud you will not hear the deep signals, if your detector has mixed audio listen for the all metal threshold signals which don't
register on the disc side usually this is a good deep target, it will just sound like a slow zing zing sound
there are some good videos of hunters using excalibur on beach listening to the threshold changes in pinpoint mode getting 16" coins

I use an A.T. gold ,I have the threshold so I can just hear .Is this correct?Thanx for your response.

Just a slight threshold is good. Just enough that when you go over a deep target that you will here a slight rise in the threshold. Don't turn it up loud. Wont help that mush and can mess up your hearing... KEN

That can be a confusing question as not all detectors have the threshold hum in disc. However, every instruction I've read and on my own detectors, a light threshold hum set in all metal is the suggested way to go. The one detector I have that has a threshold hum in disc. is set the same way. IMO if the hum is a bit (or more) too loud it becomes quite distracting and offers no improvement.

What kind of detector are you talking about?
I have a Coinstrike and what I always thought threshold to mean doesn't apply to this detector at ALL! Threshold on it means the adjustment of how sensitive the audio circuit is to sound off and its not about what I call a operating threshold tone. (others are this way too)
Now, if you have a detector that operates with a running threshold tone then the best way is to set the tone is to just "audible" just enough to know its there, this way any good target (signal) can raise the tone enough for the operator to hear the change. If the tone is below audible any amount then a smaller deeper target may not be able to raise the silent threshold level to the point of audible. Its called a threshold because it sets a knowing starting point in the audible range for ground targets to start from. Raising very high would not be of any help either because that's not the "Threshold Point" and would only make running the detector for very long annoying. So, keep it low, soft and as pleasant as possible for best operation.

hey Mark ,I use an A.T.gold

Run threshold as low as possible just being able to hear small changes in ground conditions. TARGET SIGNAL NEEDS TO BE LOUDER
