"The claim that it rejects iron would need to be examined more closely, but I highly suspect the so-called target ID and iron rejection is based on target conductively, and is not true ferrous/non-ferrous discrimination like a VLF. For example, you can adjust the GB control on a White's TDI to reject small iron targets, but the results are highly dependent on the shape, size and orientation of the target. If anyone can show a video that demonstrates this detector rejecting various ferrous targets with different shapes and sizes, while still accepting all other targets, I would be amazed."
Yes , in my person i test many PI detector that they claim discriminate..... i never see a TRUE discriminator PI detector like a simple VLF design !!!!

The only PI detector with true ferrous/non-ferrous discrimination like a VLF is Voodoo -> The Voodoo Project - Published October 2020

Hi Jose ! I'll send you a video of Jose Pulse, which works 90 percent the same as the VLF detector in terms of discrimination.

In addition, Voodoo is a motion detector, which would not be suitable for such large coils. You would be better off using Delta Pulse.
