PZ Racing GPS lap timing system???

I wouldn't recommend using iPhone apps as the GPS isn't great and the times may well be misleading (but better than your wife doing it

)

Drop outs on iPhone are commn place. I plotted Harry's against VBox and PBox and was a significant difference at Spa

Although I have tested a VBox at Silverstone and not against Harrys I wouldn't dissagree with you. You can see the speed suddenly jump in areas on my video almost as if the GPS signal has caught up all of a sudden.

Its 'reasonably' accurate and I use it to review my lines and where I am on and off the power more than anything else. The speed and time are just a guide.

I'm sure the flatter and more open places might be ok, but the hilly and bridge covered circuits would be worse, aka Ring

What do you use Shim? Vbox?...

new app.. Sy's wife timing will be out soon! 7.99 & knocks 1-1.5 sec's off your times

I think the Vbox gives more information, this is the route I will be going next year

Nathan does a good deal

I have the PZ but haven't had time to test it yet. Had it with me at the last race but it ran out of batteries as some numptie forgot to switch it off before bringing to the weekend and didnt bring spare batteries!

I will keep you posted when I test it, but it can do sector times.
