Kestrel's patents on a low cost precision istrument have been expanded with the model 4500. Our troops oveseas have come to rely on the accurate data from the kestrel to indicate signs of dehydration, wind, dew point, condensation, all of which it measures with grace.

I bought my first 2 Kestrel 4000 units and I must caution that with excessive use (battery changing) they eventually broke the battery door on both units. I'm subtracting one star from an otherwise perfect product because Kestrel has chosen not to incorporate a green rechargable option yet and still uses AAA alkaline or lithium cells - HOWEVER -

In the earlier models (4000) if you wanted a graph over time you had to leave the unit turned on CONSTANTLY - batteries were dead in 3 days, which wasn't bad for a 2xAAA alkaline system. With the 4500 you leave the unit turned off and give it a wakeup period (say every 30 minutes) when it takes measurements of every weather reading and stores them in... Read more
The Kestrel 4500/4500NV is a pocket sized weather station weighing in at a mere 102 grams with NIST tracable accuracy, trend recording data for plots of barometric pressure over time (in days) or windspeed (in minutes), and numerous calculations of wind chill, heat index, and many more. Its compass is one of the most accurate electronic compasses I have used (and I use garmin's frequently) with a reading to the nearest degree that is repeatable. Using just 2 AAA batteries and an included brace to prevent them from rattling causing compass errors, it provides 400 hours of active usage or months of weather trend logging.

Basically the older 4000 unit had a few bugs, mostly with the extreme case sealing to make the unit watertight so it could be left outside overnigt or dunked in the water. While you could buy the 4000 in grey or orange and get the same electronics, the olive drab 4500NV is substantially different than the 4500 yellow model. The NV stands for night vision... Read more
During the Iraqi and Afghanistan campaigns, soldiers needed to know fairly precise windspeed for artillery and marksmanship purposes. In fact, some rifle scopes today expect the user to own a kestrel wind speed meter and need the data from the meter to compute the scope adustment.

Kestrel worked with the US DOD to make the 4500NV (after all the 4000 was hunter orange) - in fact they worked so hard that the backlight on the 4500NV (NV stands for Night Vision) is so dim that it is not as useful as the standard 4500 (bright yellow case) which has a nightlight like a timex indiglo watch (too much for our Gen 3 NV systems).

The download data function *IS* very slow - the reason is that the case is weather sealed and the data is sent and received using infrared diodes on the back of the case. Back in the days prior to usb, these went to a 2400 - 9600 baud serial line, and they were fine. The USB version of the data adapter maintains the clock rates of the old serial... Read more
