It always seems like no matter how hard you plan for an outdoor trip, weather always turns out to be factor in your activities. And when you're out in the middle of nowhere, you can't just turn on the Weather Channel to see what's going on. Luckily, Brunton's ADC Pro ($250) is here to help. The tiny device gathers and records all the key weather conditions for you, including temperature, barometric pressure, relative humidity, heat index, air density, wind speed, wind chill, dew point, wet bulb, and more. With all of this info, the gadget then predicts the coming 12 hour's weather.
