Yes, flavor. I added a sear burner to my old Jenn Air gasser. Steaks done in 4m total. First time I used that burner, my family and I were FLOORED at the improvement. Total pro steakhouse results.It there a big advantage cooking at 1500* vs 700*?
For me it's for the flavor,because I had an infrared unit on a gasser yrs back. Plus since I picked up my 640 pellet grill I got rid of the old gasser and charcoal grills. My pellet grill can put a nice sear on a steak. But,I often smoke multiple cuts along with different types at once. With one of these rigs I can quick sear as the different cuts are coming up to temp off the smokers.I have never used an indoor or outdoor broiler. My Kettle can get pretty hot and I have a Weber gas grill that gets pretty hot. It there a big advantage cooking at 1500* vs 700*? That large website has a portable unit for $170. Might be a fun toy, but not sure I need one (yet)
