Weatherguide Review
I couldn't wait to get my hands on the Weatherguide by Precision Navigation. It seemed to take forever. Now, this may not seem like a big deal, but at the time of this writing, Los Angeles, California is right in the middle of a very rare weather phenomena...that's right...rain! I figured this was a GREAT time to play with the Weatherguide...when we were actually having some weather! The heart of the Weatherguide is the sensor module. Housed inside a case that is similar to a Palm modem, the module uses two AAA batteries (that last about 4-6 weeks) and some sophisticated sensors to continually track and store temperature and air pressure. The sensor stores the last 24 hours worth of data to provide forecasts. Before you can begin using the Weatherguide, you need to calibrate the sensore module. This is done by entering altitude in the calibration screen.
What's really neat about the Weatherguide is that it's constantly working, whether it's plugged into the Palm or not. Simply snap on the module and run the software, and you'll always know the weather! I found this to work better in theory than in practice however. Over the course of the week, we had on and off rain. Unfortunately, the Weatherguide predicted clear and sunny skies on a somewhat regular basis-even when it was pouring outside! The temperature and pressure readings where accurate but for some reason, the forecasting was way off. I talked with Precision Navigation about this and they said that based on research they have found that forecasting with barometric pressure alone is approximately 65% accurate. If they were able to include wind speed in the algorithm for weather forecasting, the accuracy increases to about 80%, but obviously, it wasn't possible with the Weatherguide. Another downside is that the module itself is not weatherproof and is not really suitable to be left outside. I carried the Weatherguide with me while driving around town for work, and I noticed that the temperature registered a little bit higher than normal from being inside the truck all day. Another thing that I don't like is that all data is lost when the batteries are removed, and it takes another 24 hours to calibrate. I wonder if this is something that could be remedied by being built into the software or not. Being only an armchair meteorologist, I really don't know. All in all, the Weatherguide is a pretty cool piece of hardware and definitely a must-have if you are a total weather junkie, however the performance doesn't quite measure up the price. You'd be better served buying a weather band radio for under $20. It's a quality product, and I had fun with it, but I can't justify the price. Also, I didn't see anywhere on the site where the accuracy was stated. I think this is an important piece of information to consider. The Weatherguide retails for $79.95 and is available through Precision Navigation's web site. Note: Weatherguide is NOT compatible with Palm V or Palm VII (unless you use Palmdock). What I like: Accurate Temperature and Pressure readings Doesn't need to be plugged into the Palm to collect data Simple user interface Easily portable What I don't like: Weather predictions not accurate Not weather proof Some data lost on battery change Flimsy label on bottom opening(same as navigator) 3 out of 5 Rating ![]() |
