Recommendatins for a timing light gun that works with msd?

Hi guys!
I have bought the timing light by Equus 5568 this week. Today I tested it and it doesn´t work right.
I was told that this timing light doesn´t work with a msd-ignition setup.:bonkers:

Can you recommend a DIGITAL timing light that works with my msd-setup?

Thanks, Günther

cheapest non dial back equus works all the time. Have several dial backs and 1 non dial back. It's the only one that reliably works w/ all boxes.
