Which Traeger do you have? I will say it’s not the same a direct heat grilling but I have the 650 pro and once I found the hot spots, I can get a solid sear. For me it’s the first 1/3 of the grill close to the hopper and then entire bottom 6 inches of the grate horizontally
Actually not sure. It is about 5 years old and got passed down when my FIL was looking for a smaller footprint grill to make more room on his patio.
But it certainly isn't the same sort of sear I can get off of a roaring Kamado.
