Yellow ThermoWorks smoke X, 2 probe bbq/kitchen/smoker thermometer for precision cooking. It comes with two probes, a primary unit, and a remote handheld unit for keeping a close eye on your cook which works throughout the entire house/yard. Handles extreme temperatures and is calibrated to less than 1.5 degree Celsius of true.
Love this thermometer, only selling because I upgraded to a thermoworks product with more probes.
