I use Computech RaceAir handheld. I have 11 No Box/PRO ET championships with it.

My pit partner also uses Computech but it interfaces to Crew Chief Pro. He also has a couple of Championships with it.

I like the handheld, as it is mobile, and important if there are long delays while in staging.

You choose the best, recent run as your baseline using Correction Factor or DA, and then the current factor to predict your next ET.

If your combo is jetted correctly and the AFR is close to optimum (12.7-12.9 in my case), it will run within .005.

Jay/Computech answers the phone on the weekends, also.

I would also recommend DragStat ($ vs $$$) for your laptop. Created by a NHRA Super class racer (and D5 champ) out of Colorado. He also answers the phone for tech support.
