Goldscan II vs Goldquest SS

I know the Goldscan II was made a few years ago but how would these two detectors compare in performance? Didn't the Goldscan II have ground balance? Anyone have any info on the Goldscan models or maybe a used detector? <IMG SRC="/forums/images/smile.gif" BORDER=0 ALT=":)">
 
There is info a little ways down on May 19 about this, as well as, a search feature at top of forum, let your fingers and mouse do a little work!!!
 
Do you mean Goldscan II, or Beachscan MK II ?
If there was a Goldscan II, it was a long time ago. By the sounds of your post I think you mean Beachscan MK II.
I either case neither the Beachscan or the Goldquest has ground balance on it. They do incorperate SAT and that auto re-sets the circuit as your sweeping. It's what makes detectors motion mode dependant. It is done to stablize the detector circut as the coil is being sweep over the ground. On the later Beachscan MK II's, and the Goldquest's it's adjustable by the user.

Had the old Goldquest friend had a Goldscan he said that you could tune out red bricks with the Goldscan.
 
Hi Bill the Goldscan was in prodution from 1983 to 1993 it had a ground balance and was designed for the tuff soil conditions of the Australian gold feilds. I was wondering how it compared to the newer production models?
 
I'm not talking about a Goldscan 4 nor do I see anything about the Goldscan 2... The detector I'm talking about was made from 1983 to 1993. But thank you for being concerned about my mouse, it works just fine. <img src="/metal/html/shocked.gif" border=0 width=15 height=15 alt=":shock">
 
Hi Beach Bum,
The Goldscan II was the model replaced by the Goldscan 4 according to Eric's post on the Geotechnology forum. (See his post on Sunday 27 April 2003, 13:10:06). I have added a link to that posting.
I do not know any of the specifics about the GSII but the GS 4 also had a ground balance, so I would assume the ground balance on the GS 4 would be as good or better as the GS II. Also, the GS 4 owners manual indicates the GS 4 detector is an improved version of the previous model and has more features.
With that in mind, I would think any info on the GS 4 would give you an idea of how the GS II might compare to the Goldquest
I do know the GS 4 is a single width pulse unit that when fully ground balanced would ignore certain targets. The window of such targets is narrow but it is there. Overall, the ground balance works quite well on the GS 4 but does display a distinct reduction in sensitivity when compared to the non-ground balance mode.
I would also suspect the GS II had most of the other features of the GS 4 which included a form of push button tuning, rather than an autotune or SAT. The audio was most likely a "putt-putt" type sound that increased in frequency rather than a continuous tone that increases in volume like what is found on Eric's latest units.
I believe the GS 4 has a minimum pulse delay of about 15 usec and I would guess the GS II would be about the same. With that in mind, the Goldquest should be more sensitive to very small gold.
I would expect the GS 4 to have a little greater depth on non gold items because of the longer pulse width, but I find that my GQ clone seems to do about as well depth wise as the GS 4 on the more typical medium size nuggets we find in the US and does better on the real small stuff.
I hope this helps a little.

Hi
Here is a link to the GoldScan 2 field test report....
