Well, it was a nice day out so I figured I would go mess around with the explorer for and hour. I have to say it was a nightmare!! I read the book and spent countless hours on these forums for any tips but it was still a nightmare. I went to a yard that I thought I covered pretty well with my gti-1500 but the explorer would not keep quiet. I tried the iron mask-16 but until I learn this machine it was entirely to much noise. I ran the sensitivity at 20 but might have been to high. Even when I held the coil in the air sometimes it was just beeping all over the place. This thing must be a nightmare in a trash infested site. Oh well I will read the book again and wait for my mastering the minelab explorer book to come in. I would imagine I will be bumbling around with this detector for quite a while. I did manmage to dig up 2 pieces of aluminum junk that I didnt have a hard time pinpointing so I guess thats a start. I was just pinpointing with the tip. Thanks for all the guys that post their knowledge on this forum I am sure it will help me one of these days. Thanks.
