They have a thermometer with multiple sensors in it that finds the core temperature of the food you're cooking automatically, and predicts the rise in temperature over time. So the alarm goes off when it's time to pull and rest, which is absolutely amazing.

They have digital thermometers now that will map out the temperature curve and even predicted when the meat will reach core temp. You really don't need to use them many times before you internalize the behavior.
