There is a bit of a danger warning with these Desert Gold units.
On the good side they have a manual ground balance and a threshold. 14khz, so not too high.
A choice of tone, sadly only two on a flick-switch. A DD coil stock. After market coils. Light enough and can be hip mounted.
On the bad side, the very bad side, they are made with an overly boosted sensitivity setting, giving them a false sense of depth in an air test and on mushy very even ground.
As with a lot of European units that are made with this silly over boosted sensitivity, they have also gone for a high pitched tone squeal for signal and threshold.
They are marketed for a few uses, and unfortunately one of those uses is detecting for gold nuggets and what they are calling "flakes" of gold.
To operate these units on our goldfield ground, you have to back the sensitivity that far back that they would be next to totally useless.
But the worst problem would stem from the units manual ground balance. It is very poor, and does not hold balance for half a swing.
Now, we have had great manual ground balancing Vlf detectors here for more than two decades that hold and maintain their balance on hot ground, so there is no excuse by any manufacturer for designing and building such a poor ground balancing unit as this one.
They makers, not sure if it's intentional or not, decided to call their pre-set balance on the detector A for Auto, just as a lot of manufacturers do, giving the false impression that the unit may have automatic ground balance or automatic ground tracking, when in fact it is simply a flick to a factory pre-set ground balance and isn't auto-anything.
Sadly, the Desert Gold, for a prospecting Vlf, is a Desert Dog.
