In 1982 Traeger Heating in Oregon began experimenting with a furnace that would burn wood pellets made from compressed sawdust, a byproduct of the area lumber mills, and before long introduced a home heating system that they sold mostly locally. Since furnaces sold mostly in cold months, before long they began experimenting with a grill that would burn pellets, too. Eventually they created a device with an auger to feed the pellets and a blower to help them burn.
When you are looking for a smoker, one of the features that you want is to be able to control the temperature. This means that you will be able to use both a high and low temperature for smoking everything from poultry to fish to beef to vegetables to cheese. This is exactly what you get with the Camp Chef. It has an LED digital temp control system that comes with a food probe made from stainless material.

3-Position Controller - 3 position controllers, also called LMH controllers, have just 3 temperature settings—low, medium, and high—which correlate to roughly 225°F, 325°F, and 425°F. They feed pellets in fixed cycles that are determined by which setting you choose. With just three settings to choose from, though, you have less control over cooking temperatures than more advanced controllers. These controllers are often found on lower priced pellet grills.

Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
