Hi Guy`s
OK this is not laser related.....
l am looking for a large LED Display panel that has a counter that can be triggered with a Start Button & stopped with a Stop Button.
The general idea is that a person hit`s the Start button & run`s away from the start position & when they reach the end position they hit the Stop Button & the Counter Record`s the time Elapsed.
The LED panel size i reckon size wise around 8 foot by 3 foot
