Default Digital timing light, how do they work

I have always used the strobe type timing light but am interested to know how the digital ones work. Do you still have to aim it at the timing scale or is there some other kind of magic at work here. I have a 71 454 and it is really hard to even see a glimpse of the scale to shine the timing light on. Jack

The digital lights have a dial that you adjust to desired advance degree, such as 34*. Point strobe and line up the damper's mark with the zero mark on the timing tab and you have 34* at that rpm. I have a Snap-On dial back and a Craftsman standard light. Personally, I like the Craftsman and degreed dampers or timing tapes. Each to his/her own...
