I'm getting old and have not been prospecting for few years now. So modified SPP and some coils are for sale. Pick up from Blacktown area only. Will not post . Whole lot $750 bank transfer or cash.

Bleach and hydrochloric acid works reasonably well, but gold must be in very small pieces and must not contain much silver. Karl

Yep, you need some sort of license to buy it. I know that high concentration stuff can be used for no good, but I only need 45% acid to refine gold. Still no go. Karl

Unfortunately, nitric acid is impossible to buy in Australia. Karl

Hi John What model is it , or what is the towing weight? Thanks Karl

I'm still using SPP fitted with conductivity switch, mostly to detect goldies from parks areas full of bottle tops and other iron junk. But haven't been out to detect for gold for while. Karl

Hi Silver I won't know what was in the letter until I go to see my sister in few weeks time. But what make it spooky is that the letter was delivered on the day when you usually receive greeting cards for your birthday. I'm not good on the math, but I think that there is 365 to 1 chance to...

Yes and pigs will fly. Some of it will happen, but over all such predictions are over optimistic. Most likely we will have world war 3 and go back to bow and arrows. Karl

Same with me. I do no remove squashed cans as it would do too mutch damage to the ground. And I want to be on good terms with council staff. Karl

It is not always possible to remove junk from the hole you have dug. Couple years ago I was detecting in new place and got very faint signal. As I dig the hole signal got louder and louder. At about two feet detector was screaming, but no target to be seen. At this stage I started to have a...

Those numbers on you map are most likely survey bearings and got noting to do with the latitude and longitude of the place. Karl

Bit of truth in it. After the flooding you will find in some bends of river or creek flood gold. That is a gold that been just deposited by the flood and is sitting right on the surface. Karl

Thanks Dr Duck. Karl
