The ‘Merlyn by BOLA’ Spin Bowling Machine – which was developed by Stuart & Williams (BOLA) in conjunction with the England and Wales Cricket Board – was greeted with praise and enthusiasm by professional players and coaches alike when it first went on sale last year. The ECB were searching for a means to extend the experience of first-class players against top class spin bowling and after receiving a design proposal and viewing a mechanical prototype twenty machines were ordered which are currently in use at every first class county, the England test squad and the ECB Academy. ‘Merlyn by BOLA’ provides the coach with the flexibility to deliver any combination of leg-breaks, off-breaks, top spinners and arm balls that he or she requires. The ‘easy to use’ switch panel allows complete control of line, speed, flight and the amount of top spin and side spin imparted to each delivery. The machine can be programmed to deliver any 'over' the coach can conceive.
