The strong current in the canal

Test data collection in a strong current with the camera mounted on the scooter

  • Test how the scooter/rig/camera combo behaves in a strong current
  • How fast does the water flow in the parts exposed to the current? Too fast?

I ran a test (2024-06-08) by drifting through the canal between the 2 gates, knowing it’s 270 feet long. The length of the footage gives the elapsed time, so I’ll get an estimate of the drift speed.
