The listing, Oregon Scientific thermo sensor, 433 mhz cable free thermometer has ended.
This nifty meat thermometer comes in quite handy when you need to multi task. Used 2 or 3 times so there is some wear on the lettering. I have two and don't need them both. It has a wireless connection and you cary the receiver with you. You can check the temperature without running back to the cooker. It has settings for any type of meat you can think of. I turned it on and took a few pics to demonstrate this versatility. Runs on two double and two triple A batteries. Would make a great stocking gift for the grill cook in your life. I have not used it beyond 30 ft and do not have the manual but you can most likely find that online or from the manufacturer.
