Hi, I just had to register and reply to this thread. I own a Fisher Gold Bug 2, a Gold Monster 1000 and now a Whites Goldmaster 24K. Ive also owned a Goldmaster Vsat, Goldmaster III and a GMT. Having used all of these, I have to say that the 24K isnt the most sensitive of the high frequency VLF's out there. Right now, the old Gold Bug 2 with the 6.5x3" is still king of the heap and the GM1000 is able to beat that under some circumstances. BUT, the 24K has the smoothest ground balance Ive ever used and rock-stable threshold. It finds deeper sub-gram gold than all of them using that 6.5" concentric coil. I had the opportunity to run side by side with a friend using a GM1000 and although he got 6 bits of gold to my 2, all but one of them was under .05, whereas my 2 weighed .4gm. I also found 22 bits of junk, versus his 4. All of this was from a patch that has been completely hammered over 3 decades. Last few times I used a GB2 there, I got nothing. Methinks the higher coil power and the matched concentric coil along with the XGB tracking make for a very powerful new machine for small gold. I am very keen to try the upcoming 6x3 shooter DD coil soon as the 10x5 seems pretty good on hotter ground here in Victoria. I'll keep you all posted with my finds. One thing I MUST say about the GM1000 in comparison though....some guys here are using them to great effect by ignoring the basic rule of reducing sensitivity to allow proper ground balance. They run them flat out at manual 10 sensitivity and then cannot even ground balance....but on quiet or mild ground, the digital audio of the Monster eliminates much of the noise and the tiniest gold can be 'plucked' from the pops, clicks and farts of the SAT adjustments and hot rock re-tunes.....but only by those people who have their 'ears tuned' to the sounds properly. Me personally, these noises are maddening and I rush back to the smoothness of the 24K and listen for the bigger, weightier targets. Stay tuned for results here folks!
