best coil Kalgoorlie way

hi i have hired a 3000,3500 or an extreme (what ever they have avalable ) but i am wondering which coil would be best for these detectors.I am detecting in an area around Kalgoorlie-leonora way
thanks for any information.

people keep telling me use a 14 inch mono or dd coil on sd2100, so got one last weekend for my modified sd. see how it goes this weekend around southern cross to parker range area, trying coolgardie kal soon as well.
let me know which coil u find useful, i still new at this game

well where going in oct where taking a nugget tech dingo
tell ya how it go's
cheers

Hi Big chop
I have used an Extream around Kal and found that in some areas a 16" mono works ok , particularly with the soil switch in " Sensitive "
Other places with high Laterite and weathered altramafics will be noisy so I would take a DD as well , at least the standard 11" DD . This can be run with the RX switch in "E" (or M on the later GP's ) for more sensitivity on the small bits . You will dig more ground noises and hot rocks than with a GPX , but these are still very capeable machines .

i liked the 14x9 mono coiltek

For mineralised ground on the GPs, I had great success with the 15x12 dd commander when I had my 3500

Gday big chop

A coil that I found very good in heavily mineralised ground with the gp extreme and then the 3500 was the coiltek 14" round dd pro coil, in some areas an 11" or 14" " mono either round or eliptical will be ok.

cheers
