Hi Phil
My settings for the GP3000 are about 13 posts below .Jonathan Porters Vid at Aurum Australis is worth getting for tips on getting the best from this machine.As far as the signals go did you have any metal on you ,buttons or eyelets in runners or pick to close.If not that perhaps not groundbalanced properly.Hard to tell ,they are reliable machines so it will be something simple

Yeah Phil
If you finding small lead its working OK,Get that threshold paper thin (just on) Ground balance it and set it to fixed.Get a bic lighter wave it across moving it away till you can just hear it.Adjust tone to suit you hearing.Deep and sens gets the best out of them.Everytime you click a switch regroundbalance them.Run in fixed and regroundbalance often(JPS VID shows how to do this quick).Click off sensitive if to noisey and try keep on deep.
If ground too noisey run on tracking and when you get a possible scrape the top and regroundbalance to fixed off the target,that way you wont track out the feint ones

Hi Phil
Level adjust to 12 oclock and back volume off a bit.To start sit them on the ground with coil flat and press tune button and dont touch it until it runs through the process. To groundbalance them set them to tracking and accurately pump them up and down from 25mm to 150mm until it quietens Hold your finger on the switch and when you reach the 25mm from the ground on the last pump click it to fixed Let me know how you go
Cheers Dig

Hi mate, I hope for your sake it's not the one my mate sold to coiltek a little while back, if so it's a dodgey machine that has been treated like a slag. It had pretty worn feet and will have a brand new foam grip, as the one he sold had a home made duct tape one. Did you get it from coiltek in Marybourough?

HI Fabphil,

Can you please explain a little more in depth by what you mean by the "coil kick in and out".
Are you hearing a response through your headphones, of the detector audio, or are you hearing the coil itself buzzing?
If you sit the detector on the ground and bump the coil with your(empty) hand does this cause a response? If so the coil is most likely buggered.
With the detector on the ground, if you bump the detector case does it cause a false response? Check and clean the coil connection and re-test.

Cheers Mick
