Finishline setup at UC Davis.  Notice that there are 4 displays at the FL.  Also note that although
it would seem odd to run cables over the track AND attach them to the timing pole --this timing pole is rock solid.  The pole comes out after the meet but the sleeve goes into the ground 4-5 feet which makes it sturdy even in high winds.
 

4 of the Micrograph boards (above and below) put together to make one good sized scoreboard.

Wind meter connected to timing system via another wireless device (SeriaLynx).
No need for an official to run it.
