Pit crew in a box

During an open track day at PMI I ran around a few laps at a time and recorded tire pressures with ambient and track temps. I'm getting conflicted data in regards to tire pressure, too long to explain but I think my problem is my pressure gauge. What would be recommended for a reliable and accurate tire guage that won't cost me $50 or more, I started school and not a whole lot of money to spend. Thanks.

I have a generic semi-heavy duty trucker type tire gauge that has a dial indicator, about a foot long hose, and a little bleeder valve on it. It has a 0-160 lb range. I got it for free when my wife had to kick renters out of the property she manages and they left it behind. It looks like hell with a cracked plastic cover over the dial face, but it works great.

A few years back one of the drivers in the garage stall next to me at PPIR was laughing at my gauge and questioned my reliance on it. He had some high dollar calibrated digital readout gauge. As an experiment we compared them. He didn't like finding out the pressure I said I was setting my tires to using my gauge were all within 0.5 pounds of his gauge...especially since my gauge is calibrated in 2 pound increments instead of 1/10 pound increments like his. That was good enough for me.

I also just searched ebay and found a few for less than $10 shipped.

I hate those digital gauges.

I have three. One low pressure mychanical Snapon that I use for the drag tires on my Saleen, one high pressure Snapon that I just bought for open track events and one old school dual tire gauge that I use at work.

The old dual tire gauge is the most accurate out of the bunch and I have been using it for over 7 years.

I thought that there might be a particular brand or such, but I guess I'll check out the trucker gauges and ebay. Thanks guys.
