    I like non digital lights. Less options means less things that will go wrong.

    If you are using any MSD stuff Don't use the dial back version

    Todd, if this is for your car with HEI, the first one should work fine. I think the pro version is constructed a bit heavier to withstand daily use.

    I have had the equus 3568+ digital advance timing light for close to 10 years and it still works great. I have used it on everything from stock HEI, points, MSD, and Mallory systems

    I've read that dial back timing lights are only accurate to a certain RPM. That rumor was enough for me to buy a $3 timing tape and use a standard timing gun

    Why not? I know the instructions say not to just wondering why. And can you use a dial back but not dial it back?

    if anyone is interested,

    found the answer, on another forum

    from : msdtechsupport1

    We recommend using non-adjustable timing lights because of their analog circuitry design. Adjustbale digital type lights tend to pick up interference from the MSD and can be off as much as 1 degree per thousand RPM.

    Also some info here where people are using them with no problems.
