That looks like a proper / affordable lap timer

[Topless]

Hey Chris,

Those new laptimer/datalogger setups are sweet. I have been using a PDA with Racechrono software ever since you opened my eyes to the possibility. I just didn't want to drop $1200 on a full dash and the old hotlap with beacon was too limiting. Very satisfied with Racechrono.

If I'm ever going to catch Dave, I'm going to need all the help I can get! Can you guys explain how a laptimer/datalogger can help me be faster?

A GPS laptimer/datalogger allows you to explore different lines or corner approaches and get instant feedback when something works (screen goes green for fastest sector or lap). You can also review your laps to see which gear worked best in turn 4, late braking into 9 unsettles the car and kills exit speed etc. Comparing lines, exit speeds, and terminal speeds at the end of a straight are very useful in skill building once you have the basics of car control.

To elaborate a bit more on what Dave wrote:
So basically you try a new approach to a corner (example double apex instead of single apex).
Your predictive laptime before entering the turn was 1:48.0, after finishing the turn it is 1:47.0 So you immediately know that this new approach just shaved a second off your lap
