Can I use Dashr 2.0 to time a 100 m or 200 m sprint?

The Dashr 2.0 timing system has a maximum range of 60 yards/meters so a single system could not record a 100 m or 200 m linear sprint or around a track. The 60 yard limit is line of sight, so you can have a course with a start and finish within 60 yards of each other.

You could also “daisy chain” systems together and add up results, but this is not what the system was designed for. It is designed for performance testing/training at distances up to 60 yards.
