Hi,
If you want a simple to use, very lightweight detector with no gimmicks, just 3 tone audio, big numerical display, sensitivity and pinpointing, take a look at the Teknetics Minuteman or the Teknetics Eurotek Pro. They are the same detector internally but come with a different faceplate and a different coil. The 8" concentric coil on the Minuteman makes pinpointing easy. This detector is like a Tesoro Compadre in its simplicity and is deadly on 8" or less targets, works great on dry and wet sand with some sensitivity adjustments and has very accurate target ID. You would need headphones or earbuds with an inline volume control with both.
