This thermometer I'd a dual-probe wireless digital meat thermometer designed to monitor cooking temperatures from a distance. It consists of a batter-powered transmitter base that stays near your grill, oven ot smoker, and a portable receiver that you can carry around or clip to your belt. We used it for smoking meats and have upgraded to a Bluetooth system. This thermometer worked great for us! Feel free to make me an offer...serious offers only...thank you
