G'day
I was thinking about the Gpx 6000 yesterday and it came to mind that possibly the internal electronics are a beefed up version of the Sdc2300 system?, why I think this is because I have been getting feedback about its performance and its ability on small nuggets, and how it performs generally, some of the similarities are, it has few controls like the Sdc but with some enhancements that the Sdc lacked like the volume control, apparently it also struggles a bit with emi with a warbly threshold as the sdc does, hence the new dd coil with it, ergonomics was an issue as well and a better balanced and lighter version addresses that complaint, and many of us also commented that a lighter better version of the Sdc would be a good thing, also the ability to change coils was brought up and then coiltek released their range of coils for it, also the antiquated c size batteries that most people replaced with the li-ion battery kits and that has been addressed also with the slide in li ion batteries.
The GeoSence feature may be a way of explaining the faster pulse timing that the Sdc has compared to the gpx's, I am not an expert on it at all, just that I have an inquiring mind and it seems to me that there are many performance similarities between the two machines, and really they could not have called it the sdc v2 or sales would drop on the sdc and it would also effect the Gpz sales too I would think, I think really it is overpriced and that itself would be a stumbling block for a lot of people particularly if you need to sell your current detectors to fund the new one as all the sale sights are now clogged with gp'x and sdc's, the prices are steady for now but will fall as people just try to get rid of what they have got so they can move on.
cheers
