power probe III & IV
 

What one do you have and do you like it..?

Looks like the real difference is IV can test efi injectors and the drivers in the ecu and the III can not..

How they hold up..

Thanks..

I've had my III for about 6-7 years. I bought it with the fault finder as a combo package. I have thought about upgrading but I may wait until V comes out. I see they have the Hook on sale for $250
