WOW! Never knew Petersen had developed that! Looks good...I think in comparison to to the vs-I or II it is probably as good. One thing to remember any digital strobe is , IMHO, not going to be as acurate as a "real" time strobe tunner. I use the Petersen Stretch Tunner (Piano Strobe). The reason I believe this, as it was explained to me, is that like L.E.D. tuners a digital strobe is going to have to have beginning and ending parameters for determining what's in tune and what's not. Apparantly the "real" strobe doesn't have this because there are many wheels spinning and you are using your eye to determine the tightest focus / tuning point. I am no expert but, I can say without a doubt, I own a VS-II ( also a VS-I but sold it) and in comparing it to my "Real" tuner the VS-II doesn't stack up. Now don't get me wrong...the vs-II is probably better than almost any needle or l.e.d. out there so buying a VS-II is still way above using the standard fair. But IMHO it is a much better buy to get the real deal. It's a one time buy! You will have it forever and will always know that you are doing the best possible job.
