DescriptionA great many things influence how well your hawk flies on any particular day. Some may be controlled by the falconer but many are simply out of his/her control. The Kestrel Pocket Weather Meter is the idea tool for charting and determining how a hawk will perform on any given day by identifying those unknown variables. It is especially valuable for the longwinger who expects the hawk to fly high in the sky and stay there for a period of time. This easy-to-use yet sophisticated instrument will help the falconer decide ahead of time about training strategies and the best time of day to fly.
Check out the list below for the types of data the Kestrel 4000 can take and how it will help you determine performance and strategy.

WHAT CAN THE KESTREL MEASURE?
Wind Speed: The rate of the motion of the air on a unit of time.
Temperature: Air temperature is the ambient temperature of the air and water vapor as measured by a thermometer or other measuring device in which the thermal element is dry and shielded from radiation.
Heat Stress Index: A measurement of the air temperature in relation to the relative humidity, used as an indicator of the perceived temperature. This will tell the falconer exactly how hard the hawk will have to work in these conditions.
Altitude: The height of an object above mean sea level. All hawks must work harder at higher altitudes in thinner air.
Density Altitude: The equivalent altitude in the ICAO standard reference atmosphere for the measured temperature, relative humidity and air pressure. A measure used primarily by pilots, high-performance engine mechanics and long-range shooters. This is perhaps the most important piece of information affecting the flight characteristics of a longwing on any particular day.
Barometric Pressure: The atmosphere pressure of the weight of the air above the measurement point, reduced to sea level. Also known as mean sea level pressure. Higher pressure results in "thicker" air meaning more particles of air flow over the flight surfaces of your hawk's body, wings and tail resulting in more efficient conversion to dynamic flight.
Volume Air Flow (CFM): The volume of air moving through a given space over a unit to time. Calculated by multiplying the surface area of the opening times the air velocity.
Wind Chill: The temperature of windless air that would have the same effect on exposed human skin as a given combination of wind speed and air temperature.
Relative Humidity: The ratio of the amount of water vapor in the air at a specific temperature to the maximum amount that the air could hold at that temperature, expressed as a percentage.
Dew-point: The temperature at which the water vapor in the atmosphere begins to condense. Any further cooling causes condensation (fog and dew). This is also the temperature of saturation at which the dry-bulb, wet-bulb, and dew-point temperatures are all the same.
Wet Bulb: The lowest temperature in the ambient atmosphere yielded by evaporating water from a wet muslin-covered bulb of a thermometer.
Humidity Ratio: The amount of water vapor mixed with one unit mass of dry air, usually expressed as grams of water vapor per kilogram of air. Also called mixing ratio.

Warranty: All Kestrel Pocket Weather Meters are made in the USA and covered by a 5-year warranty against manufacturing defects. Additionally, every single Kestrel manufactured is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard that is calibrated daily. Every unit is shipped with a FREE Certificate of Conformity that states what calibrations were performed, and the certified performance specifications.
