Im having a hard time metal detecting because of my back from a car accident i had last year. I cant bend over much do dig plugs all day so i was wondering if anyone uses a shovel specificly in parks. Looking for one that makes small plugs. Im not intrested in finding large targets mostly coins. thanks guys hope someone can help. Im a 6ft 4in tall guy so what height is recommended for me? i see there are different sizes out there.
