There has been some mention of using GPS and Radar for calibrating speed. How is this done? Who do you talk to? My speedos and Perfect Pass are off a couple MPH's and even the temperature readings on both are too. Anybody figure this out? Thanks.

There is a way to calibrate both PP and the Faria speedos. The manuals will tell you how to do them. <BR> <BR>Chris <BR>No Slip Gator Grip <BR><a href="http://www.wakejunky.com" target="_blank">www.wakejunky.com</a>

Chris, how do I know which one is accurate? The manual tells you what to do after determining what the correct speed is. There is no mention on how to actually go about getting a GPS or radar check done. What if they are both off?

GPS units are cheap these days. Just go buy one. Or you can find someone out at your lake with PP, just match speed with them, and adjust.
