Over the past several years Kestrel has steadily expanded their line of pocket weather meters. With each new model they have added features. This fall they will release the Kestrel 4500 which expands on the very rich set of weather reporting and tracking functions of the 4000.
The key addition to the 4500 is the inclusion of a digital compass. While this compass will not truly replace a navigational compass owing to a relatively low accuracy of 5°, but that is more than sufficient for the weather-related functions the compass now permits. The 4500, like the 4000, has a 2000 data point memory. Data can be recorded instantly and at user specified intervals. Complete weather data is recorded including now wind direction, crosswind, tail wind, and naturally head wind information.
I was also able to view a prototype wind vane tripod mount. This mount will ensure the 4500 remains pointed into the wind and creates a fully functional and truly portable weather station. Though the final production model may be slightly different it is anticipated that the combined mount and 4500 will still weigh only 8 ounces.
Kestrel remains, in many people's minds, the gold standard for small weather meters. With the 4500 they have created a truly portable weather station that should satisfy even the most ardent weather enthusiast. Is this something the typical ultralight backpacker's needs to carry, perhaps not. But if you are interested in really analyzing your performance throughout a trip the way you probably analyze your gear's performance starting with its weight then the Kestrel 4500 is a remarkable device worth looking at.
