The infrared thermometer isn't as good as probing the inside. I'd say it might take an hour before you reach internal target temperature, but it depends on the ambient temperature inside your BBQ of course. Be a bit gentle. You don't want it to catch fire. So slow and low just like ribs. This might be a 3 beer event.It’s been an hour. The meat probe doesn’t get a reading Too loose I guess. My infrared one works good though. It’s been 1/2 hr and it’s just getting to 140f
