Goldquest SS and bad ground

Bill,
The ground looks fairly severe. The ring I used is around the 7 gram mark and obviously generates a much stronger signal than typical smaller nugget shapes.
It's not an easy task by any stretch of the imagination to work really bad ground. You are right in that a regular coil height is critical in minimising ground noise. At least you won't miss good sized nuggets.
The Goldquest is a brilliant performer. Just get the settings at their optimal level and the machine will take care of the rest.
You may have seen on the news the severe weather Perth received over the past few days. Many of the beaches have been stripped of up to a metre of sand. I dug about 80 coins in two hours and left because I couldn't physically dig any more. It's a case of hoping for some clear ground to try and catch your breath and not get 3 or 4 targets (all good as the lighter junk has been washed out to sea) on EACH sweep.
Let us know how you go and what settings work best for you.
Regards
Tony.

On the beach I run the sat and the reject about
a quarter back from minimum on the wet sand.After reading and testing my small nugget I am going to
try to get the reject as close to minimum as possible.
One question,on very deep bobby pins do you get a double or single beep. I've get quite a few deep ones which I spend a bit too long finding

Bill,
These are my approximate Goldquest SS settings:
Dry Sand/Damp Sand: REJECT at MIN, SAT at SLOW
Wet/Saturated Sand: REJECT at 10uS, SAT at 9 oclock
Shallow Water: REJECT at 15uS, SAT at 9 oclock
Water at waist deep: REJECT at 15uS-20uS, SAT at 11 oclock (the calmer/flatter the water is, the quieter the threshold)
The main variation in threshold comes from the rise and fall of swell and waves, but this is a slow change of audio and signals are still nice and sharp.

Bill,
This machine hits hard on bobby pins. They are a pain in the *$@#.
Generally, they give me a single signal at all depths, and to top it off, nearly always sneak through the holes in my water scoop. I've installed a very strong magnet inside my scoop and this will collect most of them.
Unlike a single strand of wire, the bobby pins form an almost perfect loop (somewhat flat and elongated). There is also contact between the two sides at about 2 or 3 points.It's like having a series of small rings joined together. Get a bobby pin and bend it out, and sure enough, it will react like a typical strand of wire (double blip).
Keep the females on the beach, but not the bobby pins, that's my view on the matter.
Tony.

Where on the dial does 10 or 15uS fall. I also read your post on the bobby pins. I'm glad someone else thinks there a pain.
Thank You
Bill.

Bill,
I received an E-mail from Eric some time ago which described the breakdown of the REJECT markings. He tested one of the Goldquest's from a batch that my unit came from. I should think the readings would be comparable for most units.
The FIRST mark up from MIN equates to 11uS.
The SECOND mark up from MIN equates to 16uS.
It's then a fairly constant increase to 50uS at the final setting.
Tony.
