August 2019 Introduction: I fooled around with a Flir One For Android thermal imaging device for about three years. It’s not a device for beekeepers on a budget. I doubt I would have picked it up myself if I didn’t get it as a birthday gift. I wouldn’t call it essential for the kind of backyard beekeeping that I do, but I have to confess that I got in the habit of using it often in the winter, even though the battery doesn’t last much longer than five minutes on a typical freezing Newfoundland winter day. It doesn’t give me the most accurate thermal images of bees, but it provides an indication of whether or not the cluster is big or small, dead or alive, or dying. I don’t have to tap on the side of the hive and listen to the roar of the bees to see how they are doing. I don’t have to listen carefully with my stethoscope. Typically, I plug the device into my Android phone, turn everything on and then run out to my hives and take as many photos as I can as quickly as possible before the battery dies. I don’t think it ever lasts more than 10 minutes. I have my doubts that the built-in battery was designed for cold places like Newfoundland. Here are some sample images and video to give an idea of how it played it out for me.
