The ACCU-PROBE Bluetooth Thermoter by Napoleon allows you to spend less time monitoring your grill and more time with your loved ones. By using Bluetooth, the thermometer will alert your phone when your food has reached the perfect internal temperature and you can also monitor the temperature on the LCD portion of the thermometer. The base of the thermometer is magnetic, so you can attach it to your grill and it will stay there. This thermometer includes two meat probes, but it can hold and display the temperatures of up to four probes.
