An Interview with Minelab Engineer Mark Lawrie

The design of metal detectors well-suited for prospecting is an interesting process and not necessarily an easy one to achieve. It is a combination that blends the desires of what prospectors would like, the requirements of sales people and dealers, with the science and physics of what the electronics can achieve.
…the “One More Time” has turned into three more trips and each of the three has yielded more gold each time down.
Because these crevices catch and hold gold so well, it's worthwhile to learn how they form, which ones are good for catching gold and which ones are not.
My wife Dorothy has always enjoyed tent camping. She thought she was really roughing it at established campgrounds until I convinced her to take a trip with me to drywash for gold in a remote corner of an arid desert wilderness...
After burning more than 350 square miles, the Carr Fire near Redding, California, was finally out. Luckily our home was spared, and I had the opportunity to go metal detecting in burned areas previously too overgrown to access.
...we finally got back to this exploration effort. The old works there were up above the old camp, which was very significant in size.
Our research indicated this whole area had been claimed by Newmont mining company for several years, but when the price of gold dropped they let the claims expire, and we confirmed this with the local BLM office.
"Suh-wheet!" I exclaimed as I sprang to my feet and quickly pumped my detector coil high overhead to alert Smokey that I had just found a nugget.
