ThermoWorks SIZZLE Digital Instant-Read Thermometer

Grilling anxiety/issues stem from what you can’t see, aka what’s going on re: doneness. Over years and hundreds of grills, you’ll get a feel for this intuitively. Unless then, get it right every time with a good thermometer.

This is a mid range option from the best manufacturer which feels like the right compromise. If you don’t mind the idea of waiting five seconds vs two for a temp reading (longer than it sounds when doing this repeatedly over a 600°+ fire) you can save a little more with their cheaper options.
