I have around 3 or 4 designs on the go, sometimes they take 6 months to design and test, always a little bit different. There is also the new detector in the pipeline as well.

We are starting to run some new boards out that have a far greater performance on tiny gold and big deep gold using large coils. The new boards have a set of very fast low noise intermediate drivers added, inclusive of new components to give a different attack and decay phase shift that helps greatly with the ignoring of hot rocks.

This allows far more gain to be used while at the same time reducing the response to hot rocks and ground noises. The new settings allow the use of a large mono coil even in normal timings as to be adjustable to the point where it is far less sensitive to ground fluctuations and the dreaded hot rocks.

Now just because we put a turbo charger on the V8 it does not mean that you can wind everything full and go hoon around in the rain, you just end up doing wheel spins and getting nowhere fast.

The type of ground is the main thing that you have to deal with, red hot iron stone ground means to reduce the gain so that the input circuit of the detector is not overloaded by a huge ground signal, reducing the gain and the variable frequency control helps control the noise, 

In mild ground such as pipe clay and some river banks it is possible to run the gain nearly full on, this has not been possible before as the earth field creates too much of a weee wooo sound when moving the coil up and down a river bank.

As the biggest deepest gold is more likely to be found in normal timings the upgraded sub board allows the use of normal timings in most circumstances, even with a 24 inch coil. Tiny gold such as spurry reef or 0.005 gram bits are easily detected in Enhance mode with a small coil, running the variable frequency around 200 or more with the gain set as to allow perfect ground balance is outstanding. My own testing with a mono 10 x 5 coil on a 0.005 gram gold can actually cause an overload signal on the detector. This tiny gold was detected out to 8 cm.

The real testing should always be carried out on the ground that you intend to detect, bury a target such as a gold nugget or melted aluminium and try to get it so deep that you can just detect it, experiment with settings and coil sizes as to get the best depth without making the detector unstable and noisey.

After playing with the detector and if you get confused with the changes, its very simple to reset the detector by turning the detector off, holding the power switch down until it goes dee dee dah and turning the control to reset all, then turn the other control to do the reset. It is as basic as it sounds.

Well the Covid19 virus also known as the CHINESE virus or Wuhan Express, has really put a stop on doing any video or outdoor detecting as we are basically in a lock down situation. This has allowed me to carry out a lot of lab work trying out different arrangements to gain profiles and ground balancing. I have come up with some waveform phase mods that should allow a lot more depth on really big deep targets and reducing false ground noise targets. Only if i can get out to the test site and try it out in the real world. It works great on the work bench and reduces hot rock detection while allowing for a lot more gain.

Not yet, there is a good chance a complete new platform will be made available, but then it can all bog down and fall over.

We have movement in this area, getting there.

Ring up and ask David, he can possibly arrange something.

I doubt that any of my customers run a video camera when detecting, and how long before they find a nugget, we have video on youtube of myself digging up nuggets, by sons finding nuggets at Beaufort with modded detectors. Even me going to the test site and doing video stuff takes a whole day and slows down working on new upgrades,

There is plenty of videos from the test site, we have a lot of pictures of customers finds. Maybe i should load then all up on the site.

They should watch out making unfounded comments as the Federal court has set a precedent in obtaining ip addresses to identify and prosecute for defamation.  I have seen some of the posts and taken screen shots.

There is a lot of hype with coils, they are all mostly the same, improve one thing and lose on another.

Hi Ian,  i replied to you on your other post, all detectors come with full instruction on the mods, i guarantee that your modded detector will be far better in performance than a standard one. The new mods are fantastic.

I use a modded 4500 of course, its the best detector that i have, i also have a GPZ7000 that never gets used and a SDC that never gets used. What i have found in the past are dealers hiding behind some hidden identity posting rubbish on modded detectors because they are not selling new product.. All our mods have 5 year warranty and we have modded 1000’s of detectors. We have been in business for 24 years so where are the thousands of complaints?  It is fairly obvious that there are desperate dealers and a few uneducated people behind the unfounded comments.

Still working on new detectors, it takes a bucket load of money, but it's all coming along, the time is mainly being taken up in drafting new patents and heavy investment in DSP Digital Signal Processing. We do not exactly when these detectors will be finished but another injection of cash will get it over the line.

It is the 24th of December 2019 so my the time we have built up more circuit boards we will be referring to the new board for SD GP GPX detectors as the 2020 upgrade. Older detectors can be made just as good as, if not better than the newer detectors by swapping out older components and replacing with cutting edge technology as it is made available. I added a new board to an old 2100 detector and it can detect just as good as any of the newer detectors as long as certain criteria are met, timings can be made adjustable and the variable gain board placed just after the input stages makes a huge difference to ground noise suppression and small and large gold detection. When the weather cools off I will be making some proof of concept video's.
