First ever try at park detecting went to a spot where back in the early 80s there was a built up sanded swimming area at one of our local volcanic lakes.the water has since receded about 15 metres back and its all cover over with grass so I thought there must be some old coins and jewellery hiding somewhere around the old shore line.but not today.there were signals screaming off around me every where and using the GMT I didn't have the advantage of identifying the signals like the xtera can do so all I could do is hope for the best and dig.only ended up with a pocket of aluminum and one 6 inch nail but never mind the scenery was nice.
