GPX 5000 Ultimate Settings

A report from a very experienced prospector from Northern Queensland sounds very promising to detect good sized nuggety gold at depth and also gives a good signal on difficult to detect specimen gold. The prospector who discovered these settings wants to remain anonymous due to having family connections to a detector manufacturer. Without his testing this information would have most likely never of been published. The prospector who found these settings is using a GPX5000 detector that has been modded by myself. It has front end modifications incorporating the additional front end gain that I developed and have been incorporating into the Minelab detectors over a couple of years.

By now we all should know that using normal mode on a detector gives the best depth on larger Gold in moderately mineralised ground, Enhance and Fine Gold are very useful on the more difficult to detect Nuggets on very mineralised ground.

The new settings apply to Enhance and Fine Gold but the most outstanding improvements have been in the Fine Gold mode. The GPX5000 was used in absolutely flogged ground that had been gridded, every detector and coil combination had been used over this ground for the last 30 years. The detector operator using a 14 inch Mono coil found a 3 gram piece at a reported 60 cm and a 5 ounce Quartz specimen that ended up containing 1 ounce of Gold. This ground has been detected by the operator before and he indicated that he has walked over these targets many times and had never had any previous indication they were in the ground. The detector when in the “Ultimate settings” gave very distinctive and clear signals.

The settings

First, set the detector to factory default settings as indicated in the instruction book. 

  • Select fine gold mode
  • Adjust the factory gain to 1
  • Adjust the stabiliser to 1
  • Turn the new front end variable gain up to max

You can use normal or inverted audio, and normal or deep gold at your own preference. 

Now go detecting with a Mono coil on all the flogged ground and find the gold that has been previously missed by everyone else. The detector used this way is rock solid stable with next to zero ground noise. A big thanks to the North Queensland prospector that discovered these settings, and his extensive testing around Charters Towers, Queensland.
