It only comes in Celsius though so I have to do a quick conversion in my head and the display is hard to read in sunlight. It needs some kind of shade.
I thought I'd mention it since it took me a while before finding a thermometer I liked.
I would fill it with melted wax to water proof it. They are not water proof in stock form. Only the sensor is water proof.
