Had a Steinert Superchronograph and it worked well regardless of the light conditions as it's sonic based. A little fiddly setting it up as both ends of the chrono must be dead parallel to the bullets path. Now use a Labradar which is easy to set up.
I have an old Canadian CHRONY F that is free to anyone that wants to pick it up. Just needs a 9v battery. Live 100m from SH1, Tokoroa.
