cheap timer?
 

Can anyone recommend a cheap timer with transponder?

Something like this would be cool, maybe gps is the way to go........ but $$$$, something that logs would be nice to see how i'm improving as well.......... thoughts?

More work if you want to build sector/speed data, but I just review my own video when looking for lap times.

Well the point for me to do lap timer is so that right after a lap that I felt fast, or not I can adjust accordingly. Vs looking at footage or lap times after my session. My boss has a timer on his z06 and it helps a lot to know right then and there.

If u just want a simple lap timer, get the Aim solo laptimer.

I posted a site with a 50 dollars lap timer. It will give you the basic lap time function.

The cheapeast datalogger is your phone, they sell softwares for it for less than $100, but they do have a limit as the GPS on phones log at 2hz rather than 5 or 10 like most datalogger. The key to datalogger is their software is. The traqmate is great as they have easy to use software, but they can be very expensive. Video obviously is a great thing to have, but moving to datalog is a different ball game. If you can lay video to datalogs, it's even better. Both in terms of looks and how it improves you as a driver.

If you plan to keep tracking, just bite the bullet and spend the $700 for the camera and datalogger. You won't regret it.

Here are things you can do with dataloggers
