It is so hot around the goldfields that most prospectors are sitting in their air conditioned rooms.

I have been experimenting in the lab.

  Sure is quiet over here lately.  Must be out detecting and testing new mods.

  I going to find out about the 5000 here in a few months cause I’m planning on sending mine your way.  I’m wondering if a similar coil could be designed for the GPX series machines.

Hi Wes,

I have no idea on who sells Detech in the US,

On the 7000 / 5000.  A part of the reason the 7000 gets more deeper small gold is the coil. You have to realise that the 7000 coil has three coils inside, the transmit coil is very small and puts a lot of concentrated energy straight down onto the small gold. If you do the side by side comparison with a 14” mono it is not fair, the correct way to do side by side is to use a 11” DD  or a 5”x 10” mono.  In the US as far as i know, the coil is not so hot and mineralised thus I cannot see why the 7000 would get more gold so it must be a coil winding size mismatch.

The 5000 can have its gain increased by a few component changes and changing the timing using the modified manual tuning can make the 5000 super sensitive to very tiny gold.

Impressive results.   Where does one purchase a detact coil from here in the US and how do those coils compare to Nugget Finder?
 Woody, the one thing I have noticed with the GPZ 7000 vs a stock GPX 5000 is its ability to find small gold at depth.  A friend of mine has found almost 2 ounces of gold with his 7000 to another friends 5000’s 2dwt.  All in the same amount of time.  All of it in small gold at depth that it takes 15 or so pieces to add up to 2 to 2.5 dwt per outing.  I agree with you to a point when it comes to wasting time finding small gold but when that’s all that exists in a given area you go with what’s there. 
 Will your lastests mods that I’m considering having you do on my 5000 going to improve the small gold at depth?
  Thanks Woody,

  I miss read your response, after reading some other posts on the forum, I think I understand that you actually can change the transmit frequency with your mods to both suit the ground and the depth for the size of gold much better than what is stock in these detectors.
  Thanks Woody.

That’s a good Magazine just to expensive to get it dilivered here in the US.  Maybe when I ship you my 5000 for mods you could throw some copies in the box for the return trip.
  So I take it that none of the adjustments on the 5000 have anything to do with the transmit signal?

Hi Wes,

There is an update on new settings coming out in the Australian Gold Gem and Treasure magazine next month.

The frequency setting on the back lcd (manual tuning) has a very limited range, to give you an idea it moves this much  --- when we convert it to maximise the range it is --------------------------------------------------------------- and thus it allows getting similar gold like the SDC2300 and also allows working super hot ground with way less noise.

Matt from Ballarat in Victoria has been carrying out a lot of experiments with different frequency settings in enhance and fine gold and has been cleaning up the gold left by others.
Look for Matt Kelava on facebook and check out his videos.

  I’m curious about the different factory and modified settings and controls on the GPX 5000.  Which ones control and adjust the transmit frequency and which ones adjust and control the receive frequency.
Thanks Woody.
