I know this topic has probably already been covered (?) - is the new GPZ technology predominantly about the GPZ 7000 detector or is it all about the new coil design/configuration ?? I would be the last person to ask about anything electrical – however (with the right adapter/upgrade etc), would it be possible to attach the Minelab GPZ coil to a Minelab GPX 4500/5000 (it seems a much cheaper option than buying another expensive machine). The GPX series appears to cope very well with most coils such as mono, DD, anti-interference and drag coils – is this something we should be thinking about ?

Cheers De

G'day De.

The answer to your first couple of questions,I would say both.
All coils are wound in a way to suit a particular detectors output frequency.Firstly the electronics of each detector (GPZ/GPX) are designed to work on a completely different principal to one another. So even if you could for instance,get the plug end of the GPZs 14 inch coil,re-adapted to suit the 5 pin socket on the control box of the GPX 5000,it is highly unlikely that you'l get a good working,ground stable & smooth running coil on the GPX 5000.

G'day De,

As Kon has said the 2,GPZ/GPX detectors are a totally different Technology, also the 14" D0D coil for the GPZ has a chip built into it which the GPZ would only reckonize to allow it to run with that coil only, as far as we know. I can see your idea of a way to upgrade your GPX, but in this case no it will not work. Hope this helps with your question. Very Happy

Cheers.

Mike.

I like your thinking De, but like the others say it won't work, not at this stage anyway. The new 14" DOD coil your talking about would cost about $1200 and someone would need to be brave enough to buy one and pull it apart and change a few thing here and there to even see if it would light up on a 5000.

You would need to know what your doing otherwise you could also smoke the 5000 as well and at the end of the day there would be a dead 5000 and a dead 14" DOD coil

But in time I have no doubt that some brave soul will give it a go.

a good analogy would be trying to put diesel in a petrol motor in a vain attempt to improve mileage.
As stated they are 2 totally different technologies.

Thanks everyone, I agree it would be a very difficult and complicated process. However, I expect at some stage someone will work it all out and offer to sell upgraded electronics or modified/special coils for the very large (and potentially lucrative) GPX market. Maybe it is just a matter of time??

I have heard there is an aftermarket coil in the works for the gpx detectors that will give it much better depth , I don't know when it will reach the market, hopefully soon.

Difficult and complicated? On the contrary De.What is difficult and complicated to understand,is why Minelab decided to introduce the GPX series detectors,based around the use of single wound mono coils,being usable only in conjunction with appropriate filters,disguised in the form of Serch modes/Timings. Why create a detector that relies on filters to get the coil operating properly/smoothly on the ground,using only 2/3 of the GPXs power potential 95% of the time,when in fact,they could have perfected a type of coil winding,that would have suited the GPXs full output power potential 100% of the time.
Ahh,I know why,for how else would Minelab be offloading,drip feed,model detectors,year after year? We are not all that much better off today,using the latest release GPZ 7000,than what we were,with a properly tuned SD 2100 using well made dd/mono coils.
I'v mentioned this before and I'll say it again. Minelab or any other detecting company for that matter,are quite restricted by certain governing authorities,which take priority over that of the hobby of metal detecting,in what they allow hand held metal detecting companies,to design/produce/bring out,concerning the out put power of electrical/electronic equipment,such that governing metal detectors (less China of course Laughing)
It is not so much the coil windings that have restrictions or limitations on output power effecting sensitivity/depth,as much as the electronics in the control box,towards powering the coil.
One just has to read the label glued to the underside of the GPXs control housing,to get a clearer picture of what I'm referring to.
One would have to be naive in thinking, (and not referring to anyone in particular) that we lack the technology to make detectors operate in a more efficient/quiet/powerful running manner,when man is sending millions of dollars of high tech,complicated electronic equipment,(such that of satellites) hurdling throughout space.

This could level the playing field a little more - another coil configuration/design for the GPX's (I hope they also consider releasing a similar 20 or 22 inch coil). Looking forward to hearing more about it.

Shocked The GPZ 7000 has 6,060 ft of fine wire in the coil, Minelab told me so..........
