I bought a Flaming River self powered light from speedway. I didnt see the red ferret style until I searched again today.
Im sure the flaming river will get the job done. I might buy a Ferret later on.
A flaming river timing light is like using a bic lighter to see your timing marks especially during the day outside like at the races.
I bought a Flaming River light because everyone at the time was saying that was the way to go. Pray for cloudy weather when you need to use it in daytime. I still have an old Craftsman dialback but never bothered to check if they show different readings.
