When Traeger debuted its 2019 lineup of grills, one feature reserved for most expensive models is a sensor that will help you avoid "pellet panic." It's a tool that monitors the amount of pellets in the grill's hopper and alerts you when you're running low. Or if you happen to have the grill on while you're at the store, you can check to see if you need to pick up a refill. It can be a handy thing if you're doing longer cooks where you might not be near the grill the entire time. Starting today, Traeger is offering the same feature on the more affordable Pro and Ironwood Series models with an $80 upgrade.
