By the sound of that the return signal has changed significantly.
If that isn't it I would still assume Minelab have protection in place for both the GPZ & Super D coil technologies of some description.IP Australia said:The coil arrangement of claim 12, including: 0 a transmit coil for transmitting a transmit magnetic field; and a receive coil with three loops for receiving magnetic fields, wherein a first loop is positioned entirely within horizontal limits of the transmit coil, and the remaining loops of the three loops have parts overlapping turns of the transmit coil. 5 15. The coil arrangement of claim 12, including: a transmit coil for transmitting a transmit magnetic field; and a receive coil with two loops, each loop positioned at opposite sides of the transmit coil for receiving magnetic fields. 0 16. The coil arrangement of claim 12, including: a transmit coil with two loops for transmitting a transmit magnetic field; and a receive coil with one loop for receiving magnetic fields; wherein the two loops of the transmit coil and the one loop of the receive coil form a concentric arrangement.
mbasko said:I'm no expert on detector electronics but reading between the lines here is what my opinion is:
- the Super D coil has been developed for use on the GPZ series utilising ZVT technology to facilitate their use - thinking about putting one on a PI might be like thinking about putting your GPX coil on your VLF?
- while having a similar coil for a GPX, GP or SD sounds good, for the cost & without the ZVT technology there would most likely be very little or no advantage & worse case could be very unstable or even unusable. I think the current range of coils for a GPX etc. would more than cover most peoples requirements now in regards to depth, sensitivity at a lesser cost I.e. if the mooted price is correct, & I see no reason why they would be cheaper if made for a PI, then you could purchase a few various sized/shaped coils that will cover a broad range of situations. Remember these Super D would more than likely only work optimally anyway with ZVT technology driving them.
- Cost - if you look at current aftermarket coils there isn't a significant price difference so any aftermarket Super D coil will likely be the same. The advantage of aftermarket coils in my opinion is greater choice in coil size/shapes etc. That may be the key to any aftermarket Super D's - more choice for GPZ users.
This is my opinion only & smarter people might already be working on something but I just can't see there being any advantage of a Super D coil on a PI without the ZVT technology in the box to drive it?

Minelab said:ZVT (Zero Voltage Transmission) creates ultraconstant high-power opposite polarity magnetic fields, increasing gold sensitivity.
ZVT technology goes to the NEXT LEVEL for all serious gold prospectors, providing substantially improved depth. No longer will you be limited to using either sine wave continuous VLF transmission detectors, that struggle in mineralised ground, or square wave PI transmission detectors, that can be insensitive to varying gold sizes and compositions.

The audio circuitry has nothing to do with the detectors operating platform/circuitry except to let you know there is a target. To my knowledge they can make the audio sound pretty much like anything they wanted to but Minelab seem to stick to their signature warble & tones.

Minelab's pretty pictures illustrate nothing meaningful and their description of ZVT provides no technical information to support your assertion that, "It's not PI", although it's abundantly clear that they want to create the impression of something wholly new and revolutionary. I suspect that Phasetech has a better handle on it with his above comment, "Half pulse, half vlf may be a way to describe it."
Whether you are correct in your assumption that the audio has been configured to mimic the familiar GPX noises or I am in my conclusion that the audio is indicative of a Minelab PI detection process, remains to be clarified by those with more technical knowhow.

Is there any other settings that people are changing for better results?
mbasko said:Yeah fair call I s'pose but I reckon there's enough info out there (patents, graphs, Bruce Candy explaining it, unrelenting "new technology" statements etc.) to conclude that the ZVT technology is different. If it were still PI you would expect it to be lumped in with MPF, MPS, DVT & Seta under Pulse Induction not under a whole new heading but like you say could be a ploy from Minelab to dupe us.
