I was on another diagnostics with a yearly prescription.Seems like it had a people using all types of labescopes. One guy with a verus said that the Pico wps500 works with the snapon and that the snapon transducer was too slow for good in cylinder testing. I heard this at least twice on that forum.What's the deal? Anyone using the snappy one ? How does the Zeus stack up to the other pc based labescope s
