Just a short detail of the extreme depth I get with my Explorer XS. Yesterday whilst detecting, I got a very good response signal which appeared to be very deep. I started to dig until I was about 9-10 inches down with the object still in the hole. My mate came over and started to check with his pin point probe which showed the artifact to be at the bottom. Out came some more soil, (by now it was very sticky pug clay that sticks like tar) check again, still in the hole. Eventually I removed a small piece of the clay, when Mark checked it the object was included. I then decided to see how deep the hole was by putting my spade in, it was an incredible 14 inches, which on a large object might be considered normal, but the piece I had removed is 5mm x 5mm x 5mm and triangular. How do I know it to be 14 inches; I have filed a small groove in the steel part of the spade starting just above the blade, which is 9 inches, at 10 inches, 12 inches 14 inches 16 inches and 18 inches and the final part that houses the wooden handle measures 20 inches, so I can check quickly the depth. I have attached a photo of the object which is not rusty but does have the appearance of being silver. It is fairly heavy too. I bought my Explorer in January 2000 and it still serves me well. I'm also using Technika cordless headphones with the T-Bone transmitter which gives me superb responses to all metals. Tony Stokes - S.Glocs, UK
