It is used to check the core temperature of your meat.
If you want to have a nice pulled pork, a thermometer is essential, because you got to make sure, you will hit a core temperature between 105-115 °C ( 221- 239 °F).
The most important aspect of your bbq thermometer is that the display is wireless.
This is important, because pulled pork for example takes up to 16 hours and i bet you don't want to be outside at your barbecue all the time.
It's way more comfortable to sit at the TV, sippin' beer, your wireless display on the table :)
