Weather equipment?

[SilverDragon]

Hey guys,
I'm wondering what everybody is using for gathering weather data at the track. I'm looking for something small. temp/humidity/density. If I've got to get one for each, so be it. I am just trying to think of everything before I get to racing.. that way there will be less surprises.

If you want a cheap set-up, forget barometric pressure. Get a temp/humidity guage from radio shack and use the CMS jet chart.

You get a jet that you are happy with through trial and error and then plug that into the chart according to YOUR temp/humidity readings. Fill in the rest of the chart per instructions and you're done. Never use someone elses temp/humidty readings with your chart. Always keep your guage in the shade.
