Garmin - tempe Wireless Temperature Sensor

This sensor is accurate in a stable environment, i.e., indoors, total shade, neutral placement conditions. However, further research and development could advance the effectiveness of this tool. In my house, it reflects an accurate temperature, same as thermostat. Take it hiking, and that changes dramatically. On its first trip on a local desert trail, I moved it to a number of different locations, including boot laces, pack zip pocket, waist loop belt, and finally under the top edge of my pack on the carrying handle which was also shaded by a hat with a neck flap to provide additional shade. I checked the actual outdoor temperature on my cell phone. The sensor was anywhere from nine to four degrees off the actual temperature. It will be awhile before we have cloudy, overcast days again in the desert, and it will be interesting to see if the absence of sunlight will result in more accurate readings. I would suggest to begin with that Garmin make the housing "white" and also design it for air to pass through the housing. I am contemplating returning this item.
