gp3000 coil noise

hi everyone just bought a gp3000 took it to reef hill forest near benalla last weekend for its first try found lots of small trash but i noticed everytime i wiped my hand over the coil with a handfull of dirt i could hear the coil sort of kick in and out is that normal and what settings should i have it on i was using standard 11 inch dd any info appreciated thanks

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

hi dig24crt no i had nothing on me or the pick close i might not of had tuned or balanced right seemed to find lots of small lead not a problem it was just odd it was like i could hear the coil working everytime i wiped a handfull of dirt over it even though it was just dirt got an old sd and never had it no idea first go so hopefully nothing major thanks

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
Cheers Dig

thanks dig will take that on board thanks for the advise im still a novice

dd mate and i had it on normal not deep on normal not sensitive or salt on all metal and level adjust not quite all the way round threshold about 2 oclock signal nearly all the way and tone about 12 0clock volume full bore thanks dig hope i didnt confuse you

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

thanks dig do i put it on sensitive and deep and ill give what you said a crack thanks i had it in between sensitive and salt thanks

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?

gday donkeypunch i did get it from coiltek in maryborough on the 21st of the 3rd it has got a little wear on feet but did not come with brand new crip a little chunk out one side and had i think the initials rk teckterd on coil hope its not the same one please get back to me even if your mate knows what the serial number was would be fantastic thanks

gday donkeypunch your mates name isnt roger is it thats whats written on serial number sticker and battery pouch on harness thanks

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

gday mechanic dig 24 said it cant be much but everytime i wiped a handfull of dirt over coil its like i could hear the coil kick in and out through the headphones i dont know wheather i had it all arse up with the settings or what thanks mate
