Alfano Kronos Stopwatch
The Alfano Krono is the easiest 4 driver stopwatch on the market. With only 9 buttons on the stopwatch it is very straight forward to operate.
The Krono has the ability to time 1,2,3 or 4 drivers at time, but you are also able to split the track into sectors for each driver, this way you can see where your driver is exactly loosing time to the leaders.
This is a MUST for any mechanic or dad.
