What is the best trailer mounted weather system for drag racing?

[RockinRobin]

I've been using a Kestrel hand held unit for years. Wondering if the trailer mounted units are more accurate.
I don't take my handheld with me into the lanes. Last race I was out, it clouded up and the breeze seemed a little cool in the lanes just before I raced. My ET went down by .03 I wonder if I could read something on my phone at the bottom of the lanes from my trailer and make E.T. adjustments just before I pass the "no dial in changes" sign.

A bunch of my friends use the Altronics, with a computer program for et prediction. And they have a lot of success with it.
