Just purchased the Garmin Xero chronograph so I don't need this one anymore.
Used Caldwell Ballistic Precision Chronograph Premium Kit with Tripod for Shooting Indoor and Outdoor MPS/FPS Readings.
Including my older Samsung Galaxy S9 Android phone that I kept just to use with this chrono.
Works perfectly.
Plastic end for tightening knob on tripod cracked. Needs to be replaced. Can't imagine it would cost more than a few dollars.
