I use my drum all winter long and have used my maverick through all night cooks with temps in the teens, no problems at all. My maverick sits on my Kingsford charcoal bin, right next to the drum so ambient heat of the side of the drum may keep it warmer? No problems with my maverick, ever. Beams signal to my second floor bedroom just fine.
