Snow conditions can change by the minute. In 2006 the Kestrel 4000 helped the US Olympic Biathlon team select appropriate equipment
and wax on the slopes in Turin as an official team sponsor. All
Kestrel Meters feature an external temperature sensor making
snow temperature measurement as simple as sticking the unit right
into the snow pack. Add in wind, wet bulb temperature, relative
humidity, wind chill, and barometric pressure, and the Kestrel
3500 and 4000 are portable, full-service weather stations ideal
for monitoring any resort or facility with no setup required.
Track conditions relating to snowmaking right where the equipment
is operating. Add value to ski tours with real-time weather information.
Equip ski patrol with a Kestrel to provide condition reports
from all areas of the mountain. |

| Sailing and Boating |
|
|
 |
The Kestrel family features 14 weather meters that are ideal as
supplemental on-board weather stations for large craft (no external
power or setup required), or sole weather instruments for small
craft. Use a Kestrel 1000 to assess wind speeds and sail setup,
and step up to a Kestrel 4000 to monitor all weather conditions.
Automatic data storage and on-screen barometric pressure trend
graphs make it easy to track developing storms. Plus every Kestrel
is completely waterproof and floats, so you don't have to worry
about dropping it overboard. |

| Hang Gliding, Para-sports and Ballooning |
|
|
 |
Hang gliding, paragliding, parachuting, and ballooning all are
influenced heavily by one thing — the wind. The Kestrel 1000 offers the easiest way to accurately measure wind speed, average
wind and maximum wind gusts wherever you're planning to ride
or jump, and the Kestrel 2500 is an inexpensive way to measure
altitude and pressure. The large replaceable impeller ensures
accurate readings, and the waterproof case and slip-on cover
ensure your investment will last for years of flights. With a
5-year warranty and starting at under $100, a Kestrel meter is
a must-have for any air-sports participant. |

Anytime you are enjoying the outdoors away from civilization, it's
important to monitor the weather to ensure that you aren't caught
unprepared for a storm. Kestrel Pocket Weather Meters are ideal
for just that - slip one in your pack and you have a weatherman
on your trip with you. Barometric pressure and dew point help
to predict weather trends; wind chill and heat stress index warn
of dangerous conditions for long-term exposure. The Kestrel 4000's
extensive memory and computer interface is ideal for keeping
logs or sending information back to base camp. Whether you are
a car camper leaving for a day hike, or a high altitude mountaineer
making a push for the summit, make sure the conditions are favorable
with an easy-to-use Kestrel Meter. |

Control |
|
|
 |
Avalanche and search and rescue teams need to quickly and accurately
assess the conditions wherever they're working. A fast-responding
Kestrel Meter makes it easy to monitor exposure and heat stress
conditions. A Kestrel 4000 allows ground crews to report the
density altitude and ground conditions to the rescue helicopters
for safe evacuations. Working dog handlers can make use of Kestrel
meters to monitor the wind speed, temperature and humidity conditions
and keep their dogs working safely and effectively. |

| Wind Surfing and Kite Boarding |
|
|
 |
The local weather report doesn't do a lot of good when your passion
is wind surfing, kite boarding or any other wind and water sport.
You need to know the wind speed right where you are. For under
$100, equip yourself with the accurate, light, waterproof Kestrel
1000. Want to know the water temperature, too? Step up to the
Kestrel 2000 and measure instantaneous water and air temperature.
The Kestrel plays as hard as you do - it's completely waterproof
and floats, has a sturdy slip-on cover, and allows you to replace
the impeller in the unlikely event of damage. |

| Paddling |
|
|
 |
Avid paddlers like to know the wind speed and water temperature,
and the Kestrel 2000 is the perfect tool. Tie a 3-ounce Kestrel
onto your life-vest and know the facts wherever you paddle. Those
who choose to explore distant shores can select a Kestrel 3500 or 4000 to monitor changing weather conditions and possible storms.
Every Kestrel is compact, light and waterproof — there's no reason
to leave the weather to chance. |

Whether you fly a private plane, small helicopter, ultralight or
glider, it's critical to know the weather when taking off and
landing. One of the founders of NK is a competitive glider pilot
and his know-how is reflected in every Kestrel instrument. Pilots
who fly into unimproved locations will particularly appreciate
the Kestrel 4000 with wind speed, altitude, barometric pressure
and density altitude readings. |

What's so great about the Kestrel impeller?
The Kestrel impeller measures 1 inch across, and turns on a Swiss
precision pivot mounted on sapphire bearings. Its large size ensures
accurate readings even if pointed off-angle from the wind, and
its very low start-up speed allows measurement of the lightest
puffs of wind. If damaged, a new calibrated impeller can be purchased
for $19 and popped in without tools, restoring like-new performance.
How does the Kestrel measure humidity so
accurately?
The Kestrel features a patented dual temperature sensor configuration
for rapid response and accurate measurement. Every Kestrel is
calibrated against NIST-traceable standards, and can be recalibrated
in the field with the Kestrel RH kit.
What's that curly looking thing?
That's the patented Kestrel temperature sensor. Unlike most watches
and other products with a temperature measurement, the Kestrel
sensor is outside the case to ensure it measures the air, not
your hand or pocket. The "curls" serve to further isolate
the temperature sensor from the effects of the case temperature.
How does the Kestrel measure altitude?
The Kestrel uses an atmospheric pressure sensor and calculates
altitude based on a standard atmosphere. This is just like the
altimeter in an airplane, or an altimeter watch. It's more accurate
than a GPS altimeter, but does require periodic reset of the
reference pressure to eliminate weather effects.
Does the Kestrel have a GPS in it?
No, not yet. We may add basic GPS location to a future Kestrel
model, but we'll leave the full-blown mapping and navigation
to the companies that specialize in GPS as much as we specialize
in weather.
Do you really mean MADE in the USA?
Yes. The entire Kestrel line is designed and built in the
USA. Some electronic components have to be sourced overseas these
days, but we buy American wherever we can.
Who do I call if I have a problem?
You call us! From our Customer Service Representatives to
the President of the company, we all answer the phone and know
these products inside and out. If you have a problem, we'll
fix it. Kestrels hardly ever break, but if they do, they're covered
by a 5-year warranty. |
