Metal Detector Used: Surfmaster PI Dual Field
I hit a heavily hunted-out park near the San Lorenzo River recently and got a signal in about 3ft of water near a swimming hole. Peeking under the water with my diving mask and underwater flashlight, all I could see was a small depression in the bedrock-- a natural bowl that had filled in with sand and rocks. After spending a good ten minutes clearing out a BIG rock and a lot of sand I was able to finally reach my target; two pieces of costume jewelry and a vintage 14k 24" gold chain!
It turned out to weigh 21 grams! I have no doubt that the Dual Field's ability to shoot through mineralized rock and sand was a HUGE reason I was able to make the find. Now I can't wait to get out there and see what else may have been lost in these swimming holes!
