It's important to understand the temperature of your tires to find the right tune. This Longacre pyrometer stores all 4 of your inner/center/outer tire temps across multiple sessions allowing you to track changes and effects. Using the probe method is much more accurate than a surface scan. These are $300 new, but I'm selling this for $150. Comes with lined storage case and extra probe. Can send a pic, just can't upload here.
