Help with 1st MyChron Purchase

I am buying my son his first MyChron and it gives me 2 options for sensors. Which ones should I select? He races LO206.

Are you buying a 5? Really once you have RPM and lap times you’re golden on a 206.

CHT (head temp) is one you could use but really it’ll have limited utility for a while.

Thanks…so I’m seeing the various versions…5S, 5S 2T. I’ve read some, but knowing he’s just running a LO206, where is the line of paying for stuff he doesn’t need?

You definitely don’t need a 2T. Get a 5S and a CHT and that alone is more that you’ll ever need.
