In the early part of this century Martyn was a contributor on Radio talking about his hobby and experiences as a Metal Detectorist.  

He was a regular guest of Tony Capstick's on Radio Sheffield and listeners would know him as Metal Detecting Martyn.   An affectionate title that Tony bestowed on him.   Their rapore was hilarious and, as well as passing on information about local history and metal detecting they made a wonderful "double act".
