Aim Multichron Stopwatch

The AiM MultiChron is a handy and versatile digital lap timer, perfect for any racing environment. It can track lap times for up to four different racers simultaneously, making it ideal for coaches, teams, and track day enthusiasts. With memory for 99 laps per driver and up to 9 split times per lap, it offers detailed performance tracking. You can quickly view best laps and scroll through each competitor’s times to easily review and compare race data.
 
Innovative programming allows you to get accurate times even when your racers are close together at the lap marker: selecting 'Multi Key' you can attribute times to each racer pressing 1,2,3 or 4 button. Selecting 'One Key' you get all 4 times pressing the same key and then you attribute times to each racer. It's a quite useful mode in case of final rush.
