The only other thing I would need would be a large TV or LCD with an S video connection so we could set it up so the competitors could see their scores. In the day light, they wouldn't be able to see it off my 17" HP laptop. My laptop has an S-video out, so if we could get a large TV or LCD screen, we could do the starting and stopping of the measurement equipment off my laptop, but we could put the TV or monitor on a table and turn it to face the competitor, so he could see his score as he competes, and then between rounds, ppl could see what place they are in and there score, so they could make some tweeks before they next run, to try to gain some db's.
