Maverick ET-735 Wireless Thermometer

The best barbecue is made low and slow. The trick is cooking it to the correct temperature—but opening the grill to check its readiness lets the heat out, slowing the cooking process, and sometimes resulting in tough meat. The $90 ET-735 is a top-rated wireless thermometer that lets you monitor the temperature of your ribs, chicken or brisket from up to 160 feet away. It comes with two probes, but you can buy more, letting you monitor up to four foods at once.
