I got the 5.75" for Christmas and it STAYS on the Silver umax. It hits nickels HARD and also finds the tiniest of items with a good signal. And the depth surprised me. The earring in the photo was eyeballed and I found out that this size of gold required the a/m mode. Later on I found the gold plated stick pin-however, it gave a signal in minimum disc. I searched about an hour in the RAIN and COLD as I was so excited to try out my new toy. Ooops! forgot pics. Had to edit.
