<strong>I have been using a White's 4x6" Coin Shooter DD coil for several months now and it has been highly effective on my VX3 metal detector.</strong> Recently, I have been detecting at local parks and have literally found hundreds of coins. I'm sure many of those coins were missed by other detectors. The 4x6" coil excels at separating the coins from other metals in the ground. The coil's Target ID and Pinpointing capabilities are very precise. My deepest find so far was a dime at 8 inches. It was resting in the ground vertically, standing on its edge! Overall, I'm very impressed with the performance of this coil... It is incredible!
