That's not the Garrett propointer, for definite. The pro-pointer is microcontroller-based, no preset pots, self calibrating at switch-on.
Mr.Vratis, why do you want the circuit, do you have a faulty one? Many faults are caused by the on/off switch wearing out, water damage,( or the solid-core coil wires breaking during dismantling/re-assembly).

Has anyone managed to source a replacement switch for the Propointer? Garrett here in AU want to replace hte whole PCB Assy.

I've not seen one myself in a distributors catalogue, though I have not looked at Mouser or DigiKey. I have seen similar ones used in older PC's for the reset/Turbo front panel switches, it may be possible to install something like that.
Your switch may be repairable, depending on the fault. It is a double-pole switch, but only one pole is used, so only one switch contact is needed, handy if you've lost one. The spring could be replaced with something salvaged from VCR/cassette deck/floppydisk drive etc. The latch wire you could live without, just use as a push and hold. Your other alternative is to fit a standard push-and-hold switch, such as used on the front of VCR's.
