Pyrometers
I have searched through Trubo.net and have read Emilio's Pyrometer Primer. However, I wasn't able to find any recommendations or posts with experiences on specific brand and model of preferred probe pyrometers.
For example, is this worth the bump in price over the or the ?
I kind of like the right angle probe on the Joes Racing unit and the price is right, but I've never heard of the company. I am not ready to pony up for the $300 - $500 memory pyrometers at this point.

I was lucky enough to pickup a used longacre memory unit for about the same cost as a new non-memory, it doesn't appear much has changed with these units besides the graphics on the front.
The memory is nice since I just do HPDEs because you can usually just pull right off the track, check it and go back out so you get more accurate temps vs after cool down lap or after returning to where you are parked.

Now that I have my HANS device I have given up on checking it myself and have enlisted the help of a friend.

Thanks; that's a helpful reply and a clever idea about the voice recording for the tire temps. I will have to grab some mechanic's shirts or short-sleeve button-ups with front pockets to wear over my long-sleeve t-shirts.

Absolute temp on the surface is close to useless (the "ouchometer" in you hand is almost as good).

A simple and fast readout (with maybe lower precision) is more important than a multi-click menu to get to the right tire to store the values, which takes 2-3 seconds to even out the second decimal.
The speed of measurement was my reason for bringing up cameras. Taking a shot of each tire would take very little time. Analysis is another matter (but i imagine that the full pattern would tell more than three points, then what to do with all the information...).

the thermal camera idea is cool, if you have someone watching you as you drive? if you intend to pull into the pits to use it, wouldn't it be effectively the same as taking a infrared temp gun and read the entire width of the tire ( start inside and sweep outward). that would give you the lateral spread of surface temp, which is what the thermo would give you.
anyways, back on topic, thanks handyman for useful tip!

Professionals that tune race cars for a living use probe type pyrometers, I have no interest in surface temp readings (surface temps are more skewed by what you last did, or cool off as Emilio has noted. Core temps give better averages/data).
Checking the first tire after the last is good data.
I like the cell phone recorder idea except for the noisy environment.
Ideal set-up for me would be able to dump data to a PC for later analysis and history.
Edit: pretty sad that the cheapest memory unit at Summit Racing is $329.
This $407 Intercomp Unit will download data.
The $397 Longacre Delux Memory unit does not appear to have download capability
