Yes that would work, in theory. However, my experience has been some starters are very particular about where they stand to start the races. Our best solution has been to get a youth volunteer to follow the starter around, and ask the volunteer to be careful not to bump the sensor. Second best is to nicely ask for the starter to cable tie the sensor to the gun, which leads the false elecronic starts. The worst situation is when a starter wants to stand on the outfield for some races but the sensor is on the infield. Then we have to drag the wire across the track behind the athletes. Wired start sensors, are a hassle. I'd even say borderline impractical. I understand there's no DIY wireless system for Finishlynx so were stuck with a $2,000 upgrade or pulling the wire around.
