What is this Rock? Metal Detecting the River Torrens

I found a really unusual and beautiful looking rock when out metal detecting in the River Torrens in the Adelaide Hills. In this episode of Drew's Adventures I take my Gold Monster 1000 out for a swing along the banks and in the clear flowing waters of the River Torrens in an effort to find a gold nugget, or two. Come along with me in the great Australian outdoors and learn some tips and tricks when using this machine and when metal detecting for your next treasure or few. #metaldetecting #rivertorrens #adelaide #whatisthis metal detecting, River Torrens, Adelaide, what is this rock, gold detecting, river gold, metal detecting, metal detecting tips and tricks, Gold Monster 1000, fossicking for gems and gold, Adelaide Hills gold, unusual rocks.
