Question On GPZ Firmware Update

Recommended Posts

Does anyone think about going back to the first firmware update for the GPZ?

Has anyone felt the audio is different and better results were had with the first update?

The upgrade works good but I can't seem to get the audio where it used to be even though I wrote the exact settings down.

Just curious if someone out there experienced the same thing. No problems finding gold, just doesn't sound right.

Hi, I actually never did the update. For no reason other than I haven't gotten around to it. I usually use the same settings, but lately I've been noticing different sounds. Just seems to be running different. Unfamiliar responses to familiar ground is the best way to describe it. Not sure, may be in my head lol.

How long have you been running the latest firmware update compared to the first one?

Have had the update since soon after it came out. Wouldn't have said it has changed the audio on mine at all.

Also can't say that the new settings have made any difference to the particular areas that I work.  But that is only a few spots  😉

Edit: after reading SH's and Lunk's posts below I should clarify mine. With new options turned off my audio sounds the same. 

With locate patch on, yes it is more chattery. Sorry, should have been more specific 🙃

I noticed no degradation in the audio with the new setting options turned off. In theory if you do not engage the new settings there should be no difference. If you engage the new features, it SHOULD sound different. Are you saying the audio has changed, even if you leave the new settings off?

It is not hard to roll back to the old firmware version however, and that is probably the only way to get a real answer to your question.

I have noticed that the threshold becomes somewhat chattery in Locate Patch, and even more so when using Salty Soil; perhaps this is what you’re referring to, inthemountains?

 Also, the real benefit of the Ground Smoothing  is seen when operating in saline soils - the higher the salt content, the better. You won’t see any noticeable improvement in non-saline soil types.

Patch and Salty Ground Smoothing modes will always sound a bit jittery, this is due to faster filters. If the jitteryness is noticeable then it suggests the ground your in is not salty. Also you need to allow at least an hour to familiarise yourself to the way the audio sounds, your brain will eventually smooth things out for you similar to getting used to running the Audio Smoothing on Off. 

I've not noticed the audio sounding different with the various upgrades;

Things to Try:
Change the WM12 channel
Change the detectors Frequency via the manual tune control
Try plugging in direct to the detector rather than using the WM12 to see if there is a difference
Make sure the ferrite balance is correct, poor ferrite balance can result in a jittery threshold
Turn off the GPS especially the Breadcrumb trail
Perform a hard reset
Re-install the software (similar to a hard reset)
Lift the coil away from ground effect with coil held parallel to the ground (between knee and waist height)and listen to the threshold, does the audio still sound the same?
Lift the coil away from the ground to above shoulder height, is there a loud response as the coil transitions through the arc? If so this is salt signal

Hope this helps

Thanks JP, I was hoping you would comment on this thread; your knowledge of these machines is always most helpful.

      I updated to the latest firmware in september, sunday when I was detecting I would lose my sound through the wireless, I plugged in headphones and no sound from the machine through them either EXCEPT for turning it on, and also when the WM wireless connects I hear that (but probably from the unit not the headphones)
      Anyone else have issues, I do see 2 other threads but have tried both fixes including updating again. No dice, need the GPZ!

      JP has put up a youtube video about this new ground balancing method.

      cheers dave

      Above is a quote from Jasong, from another thread that hits the nail on the head. Somewhat a forbidden topic on OZ forums, which I guess says a lot about social media. This matter has been touched on by others when speaking about the "new age" coils on the Xs in other threads. While I`m a confirmed and dedicated Z user, I recognise because I`ve experienced the ability of these coils and how they have closed the gap( in the field on undisturbed gold), plus in some cases exceeded the Zs ability. Saying that I`ve also experienced more cases where the Z exceeds the Xs ability.
      But it is interesting and really says it all about the dominance of ML, their only true competition to their latest serious gold detector is their model it replaced. This has been so for how many years?  What are the other detector manufacturers doing? And why is it sort of "taboo" to post about this subject?

      GPZ Coil coming soon.

      Jonathan, any truth in the rumour that Minelab are considering introducing a lightweight version of the 7000? A proper prospecting detector rather than a modified military monstrousity that the Z currently is? 
      You being close to Minelab, I'm hoping you may be in a position to enlighten us. I for one would consider an aquisition should this come to pass.

      Just returned from my annual trip away (that's another story for another day), I've been out 3 times detecting since getting home and two of those were training sessions. Yesterday morning it was my turn to do my own thing for a few hours before the heat beat me to a pulp. A few minutes later and I had a plucky 1 gram nugget on a continuation of a spot I detected with my son Timothy back in July (got AU$800 worth off there for the session, much to the delight of his pocket book).

      There is a fair amount of trash and the obligatory shot gun and 22 bullets along with the added hassle of a high voltage power line, so I had to concentrate on the wide broad deeper sounding targets mixed in with the Sferic and 50 Hz noise, 3 hours of this and you find yourself needing a little lay down. This location is also problematic because it is on a slope above a straight flowing gully so the coil is opened up to even more interference dependent on where you are working on the slope.
      Long story short I plucked some nice gold for the effort which made the little lay down later on justifiable. Interestingly I pinged a solid 5 gram chunk in my old scrape from the 5000 days, a boomer signal for the GPZ and not that deep so can only assume the quieter running GPZ 7000 was clearly an advantage in a high EMI area. Just below it I got a nice deep warble that made my skin goose bump and sure enough 16 inches down a 13 gram slugster came to light pushing the mornings total to 23 grams of 97%-98% Clermont golden goodness. Considering I spent 2 weeks in WA this year without a piece of gold this was pure heaven especially since I have more signals to investigate over the next few days.

      The GPZ still continues to amaze me, if only it was lighter and more manageable so that other people could tap into its potential more fully. The weight really does detract from good detecting practices with this technology. The Super D coils really do need to be kept above saturation effect for maximum depth on the deeper pieces, the coil sweep also needs to be evenly controlled, all vital methods that are are adversely impacted upon due to too much outright weight for the average user.
