These are the three tools that I use every time I go detecting in the local parks and schools. Old English chisel (sorry Dad), Rounded off 3/16 screwdriver for probing, and a modified chalking gun for cutting plugs. The black extension is part of an old table leg. The F2 pinpoints so well I hardly ever nick a coin. If i think I'm on a good coin or a ring I'm much more careful. The plugs come out so neatly I just put them back in the hole and stamp them in.
