With the huge range of coils available for the minelab PI's depth can also be pretty massive. I found a little brass button about the size of a 5 cent piece at over 600mm deep. I was so sure it was going to be gold but alas it wasnt. That was with a 12" X 15" mono coil. What PI are you using Karl? Happy hunting JW :) Hi JW Sorry for the delay in replying - between work and a nasty bout of flu I haven't had much time or enthusiasm for hobbies during the past fortnight. Definitely wouldn't sell the PI (currently a Minelab GPX 4800) for all the reasons you describe, but as mentioned in a previous post weight is a factor at the moment and frankly there are some places where it's just a little too bulky to swing with ease. How about you - what PI are you wielding? Hi Karl, Yer that flu is real stink aye. I caught the fregin thing from the air conditioning on flying back to QT from up "home". Floored me for 3 days & felt like shit for another two weeks & still have a niggling coff. Getting back to the thread at hand. I take it you use the bungy cord that hooks on to your harness to take the weight?? I also use a hip stick when swinging larger coils. Absolutly brilliant, as you can swing a big coil all day. http://www.youtube.com/watch?v=6PmFO7WSOMA I also made up a swing arm that attaches to the lower shaft & that makes it even earier. http://www.billandlindap...cting.com/swingarm1.html Why did you get a 4800 & not the 5000?? I have been told that the 4800 was made more for the European market & more as a coin/relic detector hence it is minus a few bells & whistles that the 5000 has for gold. Although it is still ok for gold but not as good as the 5000. Happy hunting JW :) Edited by user Saturday, 4 August 2012 11:49:53 AM(UTC) \| Reason: Not specified

In saying that I certainly haven't been disappointed by its performance. Previously had a 4000 which was a good machine too, although there is a noticeable enough difference in performance between the two models to justify the expense of the upgrade. Prior to that I swung a GP extreme but when I got the 4000 I was hard pressed to see much of a difference in performance beyond the obvious bells and whistles.

Was thinking a few years ago about "up grading" to a 4500. Havnt done it yet as I am doing pretty damn well with the 3000. Went out yesterday arvo & found 16 bits for 6 grams. From what I have been told from guys in Aussie, America & Alaska is that the advantages of the GPX's are noticeable in highly mineralised ground & not so much in "quiet" ground, like what we have here in NZ. The technology in the GPX's irons out the effects on the threshold chatter from the highly mineralised grounds, especially with mono coils, making the threashold nice & smooth & making those faint gold signals hearable over the otherwise chattery threshold where they would be lost. Mono coils being more sensitive than DD & any one who has used a GP will know that the DD in cancel mode will iron out EMI (electro magnetic interference) to a great extent, but at the cost of depth & sensitivity. Better that than not being able to detect at certain spots though. I used my 10 x 5 DD in just a spot last week & snagged a small piece. So paid off for me. A mono coil on a GP in cancel mode is useless & you would have just as much luck detecting with the machine turned off. The mono coils are badly effected by EMI. I always wonder though how much more I would find with a 4500. The guys from Aussie say to me."Imagine how much more you would find with a 5000" Hey Gavin.....you better get down here with you 4500....be interesting to take you over some ground to see what you get that I have missed. Good luck out there JW :)
