[Spridgets] Finding the need for a good timing light

[WeslakeMonza1330 at aol.com]

I bought a used Snap-On light and I've been really impressed with it.   Yes 
it has an accurate tacho function and stuff I've forgotten why I would want 
 to use but did that one time.

Looking  to get a decent timing light.  I'm finding that I need one now 
that I'm  once again playing with cars.  I see some of them have a "Tach 
Advance"  feature.  Can someone explain that?  I'm used to just the plain old  
flashy light thingy.  Does this feature allow you to see what the timing  is at 
different RPMs?  Is it something that I REALLY  need?
