Basic Settings for the Gold Maxx are below, but first let me just say that probably THE most imortant thing you need to know is that when you first turn the machine on, HOLD IT IN THE AIR AWAY FROM THE GROUND for about 10 seconds before using so it can tune in properly. If you do this, you will not have any problems in the field !
Cut through highly mineralized soil
One of the strong points of the XP Goldmaxx is its ability to find small hammered coins even in contaminated Roman sites, using a frequency of 18 kHz. It will happily find good targets lieing next to iron, a test most other detectors will fail.
Discrimination or Multi-tones
Can be operated in Discrimination (single tone, turn disc dial to 6-7 to knock out iron), or turn disc off to operate in multi-tone all-metal (2 tone or 3 tone). Good targets high-pitched, iron low pitched. You soon get used to the high-pitched tones, and you will find your nail collection will certainly decrease dramatically.
Turn iron volume down
When using the 'multi-tones' options it is possible to turn the volume of iron down to zero, so you just pick up the good targets. This has no effect on the detector's depth/sensitivity.
Silencer Mode
3 position switch, 0, I, II. Most sites are ok set at I. Site dependent (remember - only works in discrim).
Ground
When you first switch the machine on, holding the detector horizontally well away from the ground, WAIT 10 SECONDS (important), turn the sensitivity switch to max (backing it off to eliminate any chattering), and then adjust the Ground switch by gently knocking the ground with the detector until no sound is heard. Average position is marked between "accept" and "reject".
Coke and the Goldmaxx
Coke can be a problem with the original Goldmaxx (not so with the power !). If you get a good signal in all-metal, you can check it by going into discrim at setting 8. This will tell you if its coke or not. However, I usually dig all good targets unless the site is infested with coke.
