Have had original Sun ,Snap On,MSD,and Sears.All non advance feature.All were good.33 years of engine dyno testing.Currently have Electronics Specialties #130.First one lasted 6 years of constant dyno work.On the second now,For under 80$ cant go wrong.WE usually ask customers to bring their timing lites to dyno session for comparison.Bill C.

When I still had my shop open, I had one of those adjustable lights that was part of my big Sun Engine ‘scope/EngineAnalyzer. I had a SnapOn, and a Sun lights as well. On my race car, I had a 36 degree mark on my dampener that I knew was correct. I checked my timing with those lights, none were right on, nor did any agree with each other. After that, I won’t use one.
Your test results may not agree. I can not imagine anybody simply assuming their dial timing light is correct.
I don’t know everything, this is simply what I observed.
