Very impressed with the Dual Field unless beach is loaded with iron. Black sand and "hot rocks" prevented me from using the DFX on certain beaches on Cape Cod Bay. The Dual Field is not affected by them. I have found 4 rings since last July. A 12gr 14K in chest deep water, a 925 with fire opal on wet sand, a tungsten band and a Tiffany Plat950 6mm size 12 at over 20" in wet sand at a beach where I have seen others detecting during the season. It finds the tiniest pieces of any metal,so be prepared to dig a lot. For a scoop, I purchased the Stealth 920i with a "raptor" handle that I was able to attach to the handle without using the SS screw. Without the "raptor" handle you will screw up your wrist because a full bucket of wet sand is HEAVY. Customer service is probably the best of all manufacturers. The settings that work well for me is "gain" at 3 o'clock position, pulse delay at 7 o'clock position, and comfortable threshold. enjoy.
