Im looking to purchase a dual thermometer to monitor the ambient temp as well as the meat temp without opening the door. I have an oven thermometer but I feel that I can't get an accurate comparison with the door thermometer due to the opening and closing of the door. I have read a few threads about them but I'm looking for brand/type recommendations. I read that Maverick is a common brand but there are many models to chose from when I look them up. Many have average ratings and some high. What do you have and what do you suggest? Thanks!
