Tabs,
I received this little gadget for Q'ing a few years ago - works very well. It tracks time and temp of your meat or grill while you sit comfortably in front the the TV watching the game and having a few too many. You can put the probe in the meat or just inside the grill to monitor the grill temp. My unit is an older model with the wireless range limited to 20 or 30 feet . This newer model says 100 feet.
