First of all, let me say I can see why others would consider the Ace for finding gold nuggets. I was finding BB size brass objects with ease in the Relics mode-must have come off a bracelet. The gold-plated cross was a special find. For some reason when I got the smooth mid-tone, I decided to give the coil the speed test as I hate to be in one place all day long with a tiny coil. Grabbing the handrest securely, I whipped the coil as fast as was humanly possible trying to see if I could get rid of the signal-it STAYED the same-possibly a little louder! I was shocked to see possible gold only to find it was gold plated. Then came one of the quarters at 1" away from a post in the COINS mode! I was especially glad to see that none of the sound characteristics were lost with the smaller coil-long tones on nickels and short bips on small foil, etc. One disturbing find along this line was a nickel next to a dime. The nickel was ON EDGE straight up and down and gave a shorter than expected signal-so that rule is more of a general one than a guide to go by-BEEP-DIG! While following this in coins mode, a large piece of gold colored foil made my heart skip a few beats. There was NO place that I had thoroughly searched before where I couldn't find more coins. I soon found it was fun to walk along the edge of a sidewalk with the coil turned slightly inward-or along the edge of a chain-link fence. In the tot lots I was right up next to the poles or under them and found a few coins this way. I made the speed test because I was pressed for time-but just couldn't wait to get out. I saw places everywhere and was constantly jumping all over the place and since I used to do speed hunts I was amazed that even tiny pieces of foil (in the Relics mode) couldn't escape the fast moving coil. One last word: If you have an Ace 150-this coil will make your day, as I hardly ever used the pinpoint button.
