Minelab GPX4500 tips, settings, questions

Might be worth spraying some contact cleaner in the power switch toggle. Mine became sticky last year and would sometimes take three goes to get it to fire up.
After a little squirt, it came good again and hasn't missed a beat since.

When I first got my 4500, I rang Minelab about the
gritty feel of the power switch.

If any problems, Send the box in and they willreplace it.

Starting to be a common problem.

Does the power on switch seem "Gritty. ?

Positive slight click when activated. ?

Hi,
The only time my gpx failed to boot was because the function select button was "in between" functions.
ie, not in one function selection or the next up or down.
Did it twice.
Cheers wilko.

Thank you all for your help, but still no joy; looks like a trip to Minersden Bendigo.

Bendigo in the morning. Hope to get it fixed.

Just back from Bendigo, all fixed and a test at Whroo on the way home. Working great, no gold but a couple of small rubbish on a flogged area. Big thanks to Miners Den Bendigo for the great service and fitting me in. :Y: :beer:

Hey Limpalot
Did you found out what the cause to the problem was?
Cheers

The ribbon from the plug to the mother board had some fine cracks, they replaced it and the switch which had a gritty feel . I will be a lot more careful about where it can fall from now. :Y:

Great news :Y: :beer:

i have all 3, 17*13 is a pinch better than the 15 evo IMO. the 17x13 seems to have been made for the 4500... the 12 will pickup smaller bits, but they overlaap each other well in terms of range of nug size. it is personal preference but i preffer the larger coils for ground coverage.

Cant beat 12 evo if you know how to set it right

I use a NF 15 inch solid round on my 4500 its a little heavy ,but I have absolute confidence in it . You have to find the gold and-walk over it and I dont want anything stronger . I just dug a superglue tube at half a metre deep within a metre of a 1:5 gram piece that was 300 mm deep.That kind of excitement I dont need.

Before I added the SDC to my arsenal and for the 5000 (also suits the 4500) I originally got the 11"" Mono, 11"DD and for diggings etc I added the 8" Commander. They are my go to for smaller stuff using the GPX.

For larger deeper prospecting I use a 15" Detech Mono and the 18" Detech concentric.

The 3 gram in my Avatar was the 1st nuggy found with the 15" mono after only 15 minutes of use. (near Dunolly)

Nenad,

Out of curiosity, what motion setting do you recommend for the 18" concentric? (in general/normal)

I'd recommend Slow if running it as a Concentric

Love my 12x8 evo coil!! Ive got a 15 evo as well but it doesnt last on the machine too long. The 12x8 seems to be luckier.
