I’m considering buying one of these kits. I would like to hear from you, if you have used any of these units. Please tell me what you think?

Goldpic 3
Gary's Pulse Induction Metal Detector
Silverdog PI
And the sniffer XR1

Goldpic 3 - has NOT the discrimination FERROUS-NON-FERROUS
Gary's Pulse Induction Metal Detector - has NOT the discrimination FERROUS-NON-FERROUS
Silverdog PI - has not the discrimination FERROUS-NON-FERROUS
sniffer XR71 - has not the discrimination FERROUS-NON-FERROUS

I did share Part List. All instructions are _similar_ to what you read in TGSL related forum and threads. All components were detaily measured, there are not mistake. Original PCB was measured, scaled in Sprint Layout, due detaily copied. I added capacitors on power supply lines for more stabile work. I added connection points for VDI too, if you will want to add VDI in future.

I assume by "Silverdog PI", you mean the Surf PI kit from Silverdog?
If so, this is a good choice.

Yes, but he seems to be on holiday at the moment. Do you have one of these?. Could you share your experience with this unit.

You will have to wait patiently for Silverdog to return before ordering a kit.

I would sugest you making the Minipulse 3 which is PI, but its not for the beginer, If you live in the UK will make you a kit of parts up including a circuit board but would need to work a price out.
