The LEDGE PRIME model comes with a redesigned digital controller that allows you to control and monitor your grill through the iOS or Android mobile application, dual meat probes and a USB port. With the new grill and pellet view windows you can keep an eye on your food without letting smoke/heat escape and see your pellet supply. The new 13.5 in. peaked lid provides enough space for a stand-up chicken to a dozen racks of ribs. Keep all your grilling tools handy by hanging them on the utensils hooks of your side convenience tray. All grills have a venturi-style firebox that creates a cyclone flame that ensures maximum combustion. They also have Sense-Mate, a thermal sensor that constantly monitors the ambient temperature. When the weather gets cold, the sensor kicks the grill into turbo mode, so you don’t have to wait long for the grill to heat up! Other features include Keep Warm Mode and Fan Only Mode with automatic shut-off to blow ash out of the firebox after you finish grilling.
