SO EASY TO USE - Works right out the box! The second you flip out the probe it starts the temperature. Take out the guesswork and eliminate overdone or undercooked food, and instead make perfectly cooked beef, chicken, pork, fish, lamb, or turkey, every time! No more sweating over a hot grill when waiting for the temperature to settle. No more squinting in the to read the numbers. When you're done simply flip the probe back and the unit auto powers off. Insert the tip into your food, and in 2-3 seconds you will have an accurate and easy to read temperature displayed on the large dial. It even works great for deep frying with oil, making bread and cheese, and brewing beer or wine.
