Experienced backpackers will tell you that expecting the unexpected is as crucial to successful hiking as a good pair of shoes. Carrying the best and the right equipment is the surest way to prepare yourself for all those little surprises that can pop up on your journey. One of the most essential tools to keep in your pack is a handy pocket barometer.
What is a pocket barometer?
Portable or pocket barometers are available in a traditional analogue style or are state-of-the-art modern digital devices. Both types measure atmospheric pressure and will help predict short-term changes in the weather where you are located. These instruments allow quick comparisons to be made with the broadcast weather forecasts that are for a more general geographical area.
Depending on the type, quality and complexity of the model you choose, a pocket barometer is capable of measuring altitude, temperature, humidity levels, wind chill, and the UV index. Many handheld barometers also have useful tools including a clock, stopwatch, digital compass, severe weather alarm, and a built-in memory to record important data. They will also give a simple weather forecast for the next 12 to 24 hours.
Most modern pocket barometers are fairly sturdy and are about the size of a standard cell phone, makingthem easy to carry in your bag or pocket. Some even have integrated carabineers so they’re always right at hand.
What’s the best way to use a pocket barometer?
The symbols on a pocket barometer give a clear illustration of the prevailing and expected weather conditions – sun, clouds, rain, snow, etc, which makes it easier to plan a trip and to avoid inclement weather.
The main thing to remember is that rapidly falling barometric pressure is bad news; it indicates that the weather is going to deteriorate quite quickly where you are. This knowledge can literally be a lifesaver if you are in really high country during winter.
A pocket barometer will certainly be useful if you’re planning a trip through a mountainous region with lots of altitude changes. You can set the device’s altimeter to alert you to specific altitude levels on ascent or descent and store this information for use on future hikes.
Where can you buy a pocket barometer?
Look in the speciality gear shops, outdoor catalogues, and online retailers for the most sophisticated models.
A basic model will run about $40-$50, while more sophisticated units can cost $250 or more.
