I've had this coil for quite some time, but it was packed away and forgotten. It was purchased for A$60 because I was intrigued.
It is the anti-interference version. Measures 12 x 4 and uses the MInelab lower rod.
Weight is decent, build quality is good. Performance in the field still remains a mystery as I've yet to use it. I gave it a quick air test just to see how it behaved on the Tdi Pro.
This version has a hot spot in the centre of the coil which appears very sensitive to small targets at shallow depth. Seems to hit fairly well at shallow depths but doesn't have much punch for the deeper targets. Test garden results on coins would give real world depth on coins between a solid hit around 15cm or 6 inches and fading fast past 20cm or 8 inches.
Useless air test with ground balance off, gain at max, in ALL, frequency in the middle, pulse delay at 10.
1 grain was 7cm
.5 gram gold coin 16cm
1/2 Sovereign 23cm
Us Quarter 23cm
Aussie Penny 25cm
Whites Buckle 33cm
So in summary it hits hard on small and shallow targets, the centre of the coil is a hot spot for sure.. Fades fast as depth increases, the big Whites buckle just managed 13 inches.
Since I managed max gain on the Tdi Pro in an EMI hot zone, the Anti-interference feature seems to work ok.. One of the things I like about the Tdi machines is the ability to plug in all sorts of coils, never know if you don't have a go.. My Tdi SL is highly resistance to EMI and the Pro less so but still very good. This coil could make more sense mounted on a Minelab around electric fences and mobile phone towers.. etc.
All the best,
There is a new show coming to TV called Aussie Metal Detectives.
