On another forum there is reference to a detector that is said to be able to detect a 50 cent coin in the air with a 18 inch mono coil at 1 metre (3 feet 3 inches) and of all things a beer can at 6 feet to 7 feet.
If you were using this detector on the beach you would need a very long handle shovel to dig to those depths on a coin or a buried drink can.
