GPZ 7000- Need Help On How To Hear Those Gold Whispers Missed By Others

[flakmagnet]

I wonder if others also notice that swinging (s l o w l y) twice over the same sweep area, many times brightens up what is an "iffy" signal on the first swing. I have found this to be true enough times to make it something I do as a matter of course when I'm in an area that requires careful detecting.

Lunk, 

So when using your setup, you don't use the GPZ WM-12 module and your volume control is on the GPZ? I just happen to have a new Avantree Torus (unopened)....another thing that needs to be charged!

Bill

 Correct, Bill, except the Torus has it's own amplifier and adjustable volume, so It's just like using a booster/speaker combo; the advantage is that the detector volume can be set conservatively, which keeps threshold instability that increases by cranking up the detector volume when using the WM-12 to a minimum, which also negates the need to use the audio smoothing filter to combat the added instability, thus allowing you to hear the faintest targets that would otherwise be filtered out, or lost in the instability when audio smoothing is set to off. 
Also, I can get a full three days of detecting with the Torus before it needs to be charged.

WOW, that's alot of great pro tips!

 I've always compared operating a metal detector for nugget hunting to learning a musical instrument. To do it well takes endless hours of practice with intense concentration. If you are thinking about anything besides the nugget underneath the next swing of the coil you are going to miss gold. I have spent my entire working career around heavy equipment and  chainsaws and I cannot pass the hearing test for my commercial drivers license but i am still rather successful at nugget hunting. 

  Technology is fantastic but it will never replace the need for hard physical effort and training yourself to not only hear but to also listen.

You forgot to throw a joke in, are you feeling OK Klunker? need a coffee or something?  Good post though, my mind often drifts when I'm detecting and it's not a good thing especially when it drifts to what I'm going to have for lunch or dinner, my detecting pace picks up like somehow swinging faster will make my next meal come quicker ?

I just like to turn the volume on the GPZ down, turn the sp01 right up to max and let my speakers do the talking.  The lower that GPZ volume the easier the little guys are to hear for me.

I like the idea of the Avantree but I've not overly liked the audio quality/stability of mine, perhaps it's some background EMI where I am causing it but they crackle too much with signal drop for my liking which throws my concentration out.   Hopefully we soon see Bluetooth LE transmitters and Avantree or some other decent company makes a similar product to the Torus with LE support, far superior than aptX LL, rather than dropping signal and crackling it will drop bitrate to compensate, the lower bitrate won't affect the detecting experience.

Phrunt, so what do you use for windy days...the Koss 30 headphones are pretty poor audio quality.

Also with the Torus you dont lose the ear buds.  And Ive dug in 100 degree heat with the neck collar and its very comfortable.

I have two GME SPK-07's right up on my shoulders, wind doesn't bother me much at all with that setup using the SP01.  Perhaps some get worse wind though so that would make a difference I guess.

As we know volume changes on detectors especially the Z, the 6K and now the Axiom affect the sensitivity of the detector, you turn the volume down on these detectors you turn their sensitivity down as well, adding a headband like the Torus that has its own volume control can allow you to turn your detectors volume down and still hear the threshold but you are killing the detectors sensitivity if you go to the extreme.

The Axiom demonstrates this to a tea, turn its volume down to 1, turn the Torus volume up until you have a nice steady threshold, you can maintain this nice steady threshold with the sensitivity on 7 on very hot ground but you`ve compromised sensitivity for a stable threshold, great powerful feature but like always there`s a compromise between noise and signal sensitivity. I recall JP touching on this subject in the early days of the GPZ, increase its volume, you increase sensitivity you also increase instability, I found 8 to be my happy median with the Z in most situations what each of us is comfortable with and can work on their ground is the go.

Cobill, I`ve gone with Lunks initial recommendation of Avantree`s Torus and use them exclusively now on the Z, 6K and now the Axiom, way to go.
