This is the ultimate BBQ gadget. The XR-50 includes a digital thermometer with four different probes to monitor 4 different temperatures and a digital receiver that allows you to keep an eye on your meat from up to 500ft away! Once any of the four probes reach your pre-set temperature, the receiver will beep so you know it's time to spring into action. It's like a baby monitor for your BBQ! Monitor up to 4 probes in C or F from up to 500ft away. Set alarms for high or low temperatures for each probe. Safe up to 716F.
