How does it sound when operating with a Threshold for the video test?

Hopefully a similar video as GotAU showing the difference before the update and then after the update with both the Speaker and then the Wi-Fi headphone that came with the 6000.

Steve since the 6000 had the CT 14x9 coil on for the test then I assume the Axiom had the 11 x7 coil on for the test? Also, settings were mentioned for the 7000 with 17CC coil but no mention of settings for the 6000 and Axiom?

Okay thanks Steve.

Steve are you using the DD or Mono coil in your GB and HR video instruction above although you did say a DD coil for mineralized ground?

To get back onto the topic of "Hot Rocks", if you suspect it to be a "Hot Rock" ground balance over the rock and if its response is removed then re-ground balance to the surrounding ground and move on. If the rock’s response continues, then it requires further investigation as it could contain gold. Recently I gave my friend a run with my GPX 6000 who called me over as he had a nice response. Digging down a few inches out came a red coloured rock, and he was curious by its response that gold may be encased within it. I grabbed the rock in hand and raised it up and down above the coil and its response was ground balanced out. I mentioned if gold was present inside then the rock's response would have continued. Therefore instead of dismissing it as just a "Hot Rock" it can be worthwhile to check.

Simon when you receive your GPX 6000 back you could test if different sweep speeds have any effect on target responses as it appears you had found with your GPZ.

Good question Simon as recently I had been told that Auto requires a different swing speed to Manual when using my Gpx 6000 and I've yet to test if so ?

Thanks Steve. I suspect then that a Pulse Induction detector capable of handling the saltwater with a Pulse Delay under 8 microseconds would be capable of detecting the tiniest of Gold Chains and Jewelry alike, if such a detector exists.

This video "Nokta makro legend is this the deepest standard mode ?" www.youtube.com/watch?v=vr6XtgbqhIc appears to show the depth potential using the Goldfield mode setting. Also wonder how well Goldfield mode would be in mineralized wet sand at the beach for jewelry and alike?

Okay that sound I heard would have been the first warning beep so from what you are saying sturt, then with no Battery bar showing (although my Battery icon was flashing with no Battery bar showing) I should expect to hear warning beeps around 5 minutes apart and at some time then the detector will shut down.

On my last detecting trip with my 6000, although not sure of of total hours I had been detecting, but at least 6 hrs, when the detector made a sound that I had not heard before. Looking down at the screen I noticed the Battery icon was flashing with no bars displayed in the icon. I assumed the sound was saying the Battery was nearly flat so I thought I would continue to detect to see when the detector would shut down. Well I continued on for a further 10 minutes or more before my friend wanted to head home so I ended up having to turn off the detector. Therefore has anyone else experienced the same thing and know how long the 6000 will continue to operate before shutting down after the Battery icon starts flashing?

If you half the size of the windings in the 6000's 14DD, as you do to find what size mono it would be equivalent too, than that would be a 14" by 8" mono coil.

A thing to keep in mind is the 14DD cable is not as long as the Mono cable so there would be a certain length that you can extend the shafts too when using a longer lower shaft as the 14DD cable would not reach the control box. From what I was told in regards to the 14DD cable being shorter it appears that was not correct.

Well done Northeast, the GPX 6000 has produced a impressive result for you compared to when you had the QED.

It appears no one can answer your question. I would think both the 11" and 17" are flat wound.

Have visited that Test Site in the video. Also the other one next to it and both sites have their targets made from LEAD. The other Test Site has the below sized LEAD, shaped like nuggets, and buried at these depths. 0.2 gram at 4” or 100mm 0.5 gram at 8” or 200mm 3 gram at 12” or 300mm 10 gram at 16” or 400mm 15.1 gram at 20” or 500mm 1 oz at 24” or 600mm 3 oz at 32” or 800mm These targets at these depths would sort out which detector is best overall. Unfortunately EMI can play havoc at times at both Test Sites. So far only one detector managed to get all of the above LEAD targets with a GPZ7000 while using its standard 14" DOD coil.

Maybe the so called 14DD is similar to the 14" Anti-Interference coil and using a Figure 8 receive winding.

I recall viewing a in-ground depth test video of the Nexus 21" CC coil up against the NF 25" XDD, although on a GPX series detector, the 25" XDD produced the best result overall. Maybe a larger DOD coil on the GPZ would do the same to a CC coil, although maybe not the 19" DOD, that was produced for the GPZ, going by all reports for this particular coil.

I expect the reason why you are now selling your QED towards purchasing a 6000.

On the top of both coils for the 6000 I notice a small groove running around the circumference of each coil in from the edge of the coil somewhat similar to the NF 12" Evo. On that Evo coil that inner groove appears to show where the flat windings extend too from outside edge of the coil. Therefore I wonder then if the same applies to the 6000 coil and maybe an indication the coils being flat wound types as well?

My guess is a 19"Z Coil from Nuggetfinder as its larger version.

I suppose it depends if a new timing on the 6000 can produce any extra depth than FG or Enhance on the 5000 since the Normal timing across all previous PI models appears to produce similar depths.

Thanks phrunt for the info at the beach, be it only a brief try on wet and dry sand with your QED set in Beach Mode 11 and then able to have the Gain set way up in its highest 10 setting with the 11' mono coil.. However, as you say it was not a black sand beach although at a guess NZ would have many black type sand beaches to test the QED out on to see if Beach Mode would handle such conditions. Now In regard to the Beach Mode default pulse delay being at 7.5uS apparently further delay is added to that default delay based on the Ground Balance number. That is, the smaller the Ground Balance number then the pulse delay is closer to 7.5uS and the higher the Ground Balance number then the delay is incrementally more than 7.5uS. I assume due to your mild soils there would be little difference in the Ground Balance numbers for all the other Modes from 1 to 10 so what would your manual Ground Balance ( MGB) number reading be when you Ground Balance to your ground before you switch your QED into Beach Mode?

Just in regards to the QED's Beach Mode which operates without a Ground Balance then it appears the Fisher Impulse AQ also operates without the use of a Ground Balance.
