Just bought a X-TERRA 305 last week for my sons and I. I did alot of looking online hints and tips and videos on how people use the X-TERRA 305 e.g. (running in all metal mode w/ full range sound) and searched many other sites for good places to locate what I'm seeking e.g. gold, coins or antiques. I narrowed down a few places around Toronto as the ground there is thawed and here I have a foot of snow still. My first site was a bottle cap glory hole so I moved on to my next spot. After about 45 min I located a big womans ring. Took it to a jeweller and he gave me a quick run down... It is 18k gold, it has 7 diamonds total 5 are square and 2 are rectangle with a total diammond total of aprox. 2, ct and has a estimated value of $6000-$7000 Woohooo what a first find.
