General Discussion / Re: DDX coils

Customers are using them, not enough feedback yet.

Hi, dont think it was me but it is simple to make, get an opamp and a mobile phone vibration unit, put in your hand in a plastic tube, plug into detector audio or if you use or booster it will drive a vibration motor directly, just a series diode to convert audio to dc.

Have not been on here for a while, been working on detector projects such as the new audio processor unit and a redesigned front end and gain system with built in noise filters.

These will work with any detector.

Everything takes longer than anticipated.  Here is some of the technology we tried out in a GPZ7000

Here is the first modded GPZ7000 video, more to come.

Bury targets and keep on testing to get the best signal.

Should have the GPZ one coming soon.

I thought it was about time to get into upgrading the GPZ 7000 detectors, initial test indicates we can make the detector quieter, more sensitive and deeper, we should have video out during February.

There is some news, just recently we were granted our Chinese patent and now we are patented in every country. We had our hands tied as we now have legal protection in China if any fake makers start up, look at all the trouble the other detector makers have had over the years with China clones. Not long to go.

The mosfet that is used a voltage limiter in GPX detectors can now be upgraded to a 250 volt 9 amp mosfet, I tested the newer p channel mosfet and the detector is a little more stable and should never have this part fail again.

send Picture of board.

We managed to obtain better batteries and a new high capacity one that sticks to the side of the detector. Look on the products page.

Mods and Price list / Two very different prospecting techniques.

My goal has been to keep my detector quiet as a mouse when I go detecting so that I can hear the most tiny ground change that may be a deep target. Most prospectors detect this way but I came across a fellow that had his detector cranked up so high I thought that there is no way that he can find gold, then I had an education.
He was using a modded GPX5000 with the front gain nearly full and the back gain on 20.  I thought no way, this guy has lost his marbles but then he showed me a 16 oz nugget he got the day before, then he showed me the pictures on his phone and I was amazed.
