Selling a used MyChron laptimer used for track day to record lap times. It does require a becon which I never need since someone always had there out on the track. 

The transmitter just has grey silicone on the seam to prevent water since it was mounted on the outside of the car. Overall it's in good condition and performs well. 

I'm cleaning the garage, I have no use for it anymore. That's the reason for selling. This is the second one of two that I owned. The pictures were just reused from the sale of the first one. The only difference is the serial number.
