Went out yesterday for a full day of detecting. Wanted to try the new semi auto ground balance. Went with pretty much basic default settings otherwise.
I have to say I was quite pleased with it. I was in one of my beat to death patches. Lots of magnetic iron stones, hot rocks. It ran very smooth. It seemed I could separate the targets very distinctively. The small bits of wire were a raspy on the edges sound. The square nails were bangers. The non ferrous targets were about the same as the gold targets. Had one really weird target sound. I always dig those. But I usually dig everything 95% of the time. But the weird sound was gold.
Not sure if my focus was just better yesterday or it was the new ground balance. But my instincts were pretty spot on, on what the target was going to be. But very pleased with the new update and settings. The take wasn't too spectacular, but I avoided the skunk in a hammered patch.
I've had my Zed now for over 2 years and less than 3. It is still under warranty.
About a year ago I notice the pixels on my screen had developed a line in the lower right corner. I called Minelab and my only option was to send back the entire package in the original box. I may have done this at the time but I would have to wait a couple of months to get it back as there were no replacements available.
Soon after I called the pixel lines went away and I have been using it just fine. Recently the pixel line has come back with even more lines. It is just a little distracting especially based on what I paid for it!
Last week I called Minelab and they said they had plenty of units available. Call them back with the serial number and they would send an RMA number for me. When I called back they asked me the problem and I told them. I was then told I don't need to send back everything. I could send them the screen portion of the detector only. They would then send me a replacement screen which also has other parts of the brains in it. I imagine there is a board in there with the video and other functions so that would be replaced also. I don't know what is in the lower part of the detector.
Has anyone had this 'fix' done and what are your results?
They told me the day they get my screen will be the day they send out the new one.
Got out to the hills for a couple hours today to have a play with the new software update on the GPZ 7000. Straightaway went to a spot that has variable hot ground that is noisy in the Normal Ground Type setting. The new Ground Smoothing with the Locate Patch option selected almost completely eliminated the ground noise, while still retaining really good sensitivity. It wasn't long before the first target revealed itself with a crisp, obvious response. Only an inch or so into the weathered quartzite bedrock, out popped a small, thin nugget:
Next I hit a patch of variable ground that was really noisy; in fact it proved to be too noisy even in Locate Patch, so I turned the Ground Smoothing off and switched the Ground Type from Normal to Difficult, increasing the Sensitivity to compensate. The noisy ground completely disappeared, and within a few swings I had a nice solid target. Three inches down was a chunky, ragged little piece of gold:
The new Semi-Auto Ground Balance Mode didn't seem to have much effect in the variable ground that I was hunting. Since this Mode fixes the X-balance, I assume it's meant more for uniformly hot mineralized ground types.
The new Salty Soil Ground Smoothing mode was very chattery, even at low sensitivity levels and with Audio Smoothing set to High, so it's very susceptible to EMI, but to be fair I was in close proximity to power lines.
All in all, a great update that provides more tools for the GPZ 7000 toolbox.

GPZ 7000 Firmware Installation Procedure (PC or Mac)
1. Download the desired firmware version from the GPZ 7000 Downloads Page. You can update your GPZ to the latest version or roll back to any prior version using this method. IMPORTANT: Ensure your battery is fully charged before updating. Do not turn the detector off at any point during the update process, or the update will not be applied.
2. Connect GPZ 7000 to the computer via the USB cable. A drive called ‘Minelab’ will appear.
3. Transfer the software update file. Open the ‘Minelab’ drive, then copy the software update file into it. The update files end with the extension ".ml3" - anything else is the wrong file. Wait for the file to completely transfer.
4. Disconnect the GPZ 7000 from the computer by ejecting the drive and then unplugging the USB cable. The ‘USB Disconnected’ dialog will be displayed on the GPZ 7000 screen. This can take up to 2 minutes to complete.
5. Upgrade the GPZ 7000 firmware. At this point if the update file was properly transferred to the GPZ, the following dialog is displayed:
6. Select Upgrade to begin the firmware update. A progress bar will be displayed. If you select Cancel, the software update file you downloaded will be automatically deleted. You will need to download the update again (from step 1) to complete the process. If the Low Battery dialog is displayed, charge your battery and start the update process again.
7. Upgrade complete. When the upgrade is complete, GPZ 7000 will automatically turn off. When you power on again, the detector will start with the new firmware.
8. Upgrade failure. If you experience any trouble applying the update, try following the update steps again from start to finish. If this does not work, contact your dealer or a Minelab Service Center.
9. You can also check your detector’s software information at any time via the Version Information function on the Reset page.

As a result of the Minelab 7000 firmware update I had reason to revisit Xchange2.
My story is that I had my main copy of Xchange2 on a computer that crashed. My backup laptop included a copy that didn't support the 3030 and 7000. I didn't want to loose the 3030 data so I renamed some files.
When I used Google Chrome to go to Minelab and download the Xchange2 program a popup came from Google and said this was a fishing site or malware site and could not download the Xchange2 program. I had to open the Microsoft Edge (Exchange Browser) and get the file and install it that way.
Has anyone had Google Chrome block a Minelab download?

GPZ 7000 Software Update 2
Get increased performance from your GPZ detector!
Minelab is pleased to announce the second software update to our GPZ 7000 detector. This FREE update incorporates a new Ground Smoothing function, a Semi-Auto ground balance setting and Chinese/Mongolian language options. This update is currently NOT COMPATIBLE with XChange 2 - see notes below.
This function implements selectable noise filters that help deal with difficult ground, especially conductive soils. The new Ground Smoothing options provide several advantages:
Reduces noise effects of salty soils Allows detecting in previously ‘off-limits’ locations Achieves maximum depth with both coils Maximises your ground coverage efficiency “With the Locate Patch setting, it is now possible to use Normal Ground Type in very ‘hot’ laterite soil… this is exciting!”
Field Tester 1 – Kalgoorlie, WA
This update adds a Semi-Auto option to the Ground Balance Mode. Semi‑Auto gives you these great benefits:
Additional control and flexibility for expert users Improved ground balance stability Another option to deal with tricky detecting conditions A specialist tool for expert prospectors “In Semi-Auto mode the GPZ is noticeably quieter over the ground in all modes but especially in Normal Ground Type modes.”

Firmware Installation Guide
1) Both the GPZ control box under the detector armrest AND the GPZ control pod user interface on top of the handle must be connected together and updated as a pair at the same time. Therefore, if sending your detector to a dealer or service centre, to carry out this update, do not send the control box alone.
2) This update is currently NOT COMPATIBLE with XChange 2 and therefore will make XChange 2 inoperable with the GPZ 7000 detector. Transfer and save Geotrails or Findpoints from your GPZ to XChange 2 before doing the upgrade. A new compatible version of XChange 2 will be available within the next few months, at which time full compatibility will be restored. Any data you have stored on XChange 2 will not be lost when you carry out the GPZ update and when this new version of XChange 2 becomes available.
3) When installing this upgrade, the detector will need to have the universal settings re-selected (e.g. language, weight) and the wireless module re-connected.
