I recently gave mine to my nephew, because I got the GTI 2500 over a year ago. I feel that the GTI 1500 is the best coin hunting on the market today. Once you learn it and its limitations, you can save time by leaving so much junk in the ground . I usually de-tune my GTI for more accurate pinpointing, and establish my targets center using the coil about 5 inches above the target. I have found over 60,000 coins with mine. You don't see too many people posting about the GTI 1500 and you don't see many come up for sale either. People hang on to these machines.....
