Kestrel Weather Tracker with Horus Vision Ballistics: FAQ

August 25th, 2010

The upcoming release of the all new Kestrel Pocket Weather Tracker with Horus Ballistics (yep, I can say that all in one breath) has triggered a decent amount of questions, comments and cyber high-fives from you. I wanted to share the latest information on the arrival of this highly anticipated Kestrel meter and answer some of your most common questions. If I missed any, please post them below and I’ll get back to you.

So, when can I get it?

The official release date is scheduled for this fall.

We make all of our own products right here at the Kestrel headquarters so we’re on top of the entire production process. We’re also perfectionists. We refuse to let you have products that aren’t up to extremely high standards. We put our Kestrel meters up against stringent NIST standards, rigid military drop-test specs, and IP-67 & MIL-STD-810 protection from dust and water damage. If you don’t know what those codes stand for, it’s basically a fancy, super official way of saying a product is darn TOUGH. Let’s just say the Kestrel is the Clint Eastwood of hand-held weather meters, or Chuck Norris even. What that means for you, is that we conduct robust rounds of beta testing and updates to ensure the product that reaches your hand is top notch. Check back for schedule updates or changes.

Which Kestrel meters will be available with Horus Atrag Ballistics software?

The Kestrel 4500 NV series will be available with Horus Vision ballistics. The Kestrel 4500 is the only model to give wind direction, which is important for long-range shooting and a perfect complement to an integrated targeting solutions system. The Night Vision (NV) series is the preferred model for the military because of its dim red back light that does not obscure or bleach out your natural vision in low light situations. Nocturnal or early AM hunters like this one too for the same reason.

You will also have the option to choose a model with Bluetooth data transfer or without the wireless technology. With the Bluetooth technology, you would be able to wirelessly transmit all of the Kestrel weather data to a laptop for analysis or long-term documentation. For example, tracking and comparing shooting competition performance against range conditions or for training purposes.

The available colors will be in Olive Drab and Desert Tan.

See what they look like here.

How much do they cost?

We will have more info on this going forward so be sure to check back at our site and this blog. You could also follow me on Twitter @KestrelChick. Fan us on Facebook and of course shoot me an e-mail: mdevlin@nkhome.com.

The Kestrel with Horus Ballistics will certainly cost less than the price of a ruggedized PDA and Kestrel meter combo. This new Kestrel meter eliminates the need for a PDA- all the critical data you need is right in the unit!

Can I upgrade my current unit to include Horus Vision software?

No. The Kestrel with Horus Vision ATrag software was specially designed and built to support the integrated ballistics solutions along with the Kestrel platform you’re used to- environmental data, storage and wireless data transfer capabilities. Sometimes we’re able to offer an upgrade option if it only involves a code change but in this case that is not possible. We do have a Customer Care Discount program where you may trade in your current Kestrel for credit towards the new Kestrel Weather Tracker with Horus Vision.

Here is a link to more info on Customer Care Discount program.

PREVENT HEAT RELATED INJURY WITH A HAND-HELD WEATHER METER

August 4th, 2010

BOOTHWYN, PA …As summer temperatures rise, so does the risk of heat-related illness and fatality. For outdoor activities, it’s critical to monitoring the environmental conditions to prevent heat stress. Whether you’re outside for sport or for your job, Kestrel Pocket Weather Meters provide instant, accurate information to monitor conditions when safety is at stake.

Athletic trainers, hikers, bikers, and anyone engaging in exercise outdoors can prevent heat injury by monitoring heat stress index for potentially unsafe levels. Heat Stress Index is used to measure the effects of the environment on the human body. The Heat Stress Index is a calculation based on air temperature and humidity, as well as a number of assumptions, to estimate what the current conditions feel like on the human body.

Wildland firefighters must perform in extreme summer temperatures. Knowing the relative humidity right at the scene of the fire allows them to make decisions for safety and firefighting strategy.  Instantly, firefighters can get temperature, humidity, wind speed, heat index, and more. In addition to getting critical information for containing the fire, heat index provides vital data in keeping emergency personnel safe. Dave Hostler, PhD, a Research Associate Professor of Emergency Medicine at the Emergency Responder Human Performance Lab at University of Pittsburgh says, “Once we have the Heat Index in hand, we can determine the intensity of our fireground rehab practices.”

When firefighters have their heavy gear on, things can get dangerously hot quickly. “We have taken a conservative approach and decided that any temperature above 80 on the heat index requires active cooling or an air-conditioned vehicle/structure for firefighter and hazmat technician rehab,” said Hostler. “Above this temperature there is always some potential for heat injury.”

Even for those of us who won’t be spending the summer in fighting fires, its important to keep an eye on the heat index and always ensure everyone is hydrated during outdoor activities. “Prevention is always better than treatment,” says Hostler. “Even using the best practices, heat stress can take hours to correct once it occurs.  Drink plenty of fluids, rest often, and think about heat stress before it occurs.”

Every Kestrel Pocket Weather Meter is backed by a five year warranty and is designed, developed, built, tested and supported here in the USA. Nielsen-Kellerman’s Kestrel Weather division has been researching, developing and manufacturing technically advanced portable weather instruments for more than twelve years and owns multiple patents on their unique features. Kestrel Pocket Weather Meters are employed by thousands of users in hundreds of different activities around the world.

Storm Spotting with the Kestrel

August 4th, 2010

Written by intern Joe Moore, Senior Meteorology student at Millersville University.

As a meteorology student, I know a thing or two about weather. So, I decided to write this handy guide to using a Kestrel to take measurements as a storm spotter. As someone with experience in the SKYWARN program of the National Weather Service, I have made this guide to align with the standards for storm spotting and reporting.

Wind
Applies to: All models (Direction: 4500 only)

To take a wind measurement, you should be in an open area, with 10 times the height of the nearest building away from you. (Eg. if you are near a 2 story home- about 25 feet tall – you should stand 250 feet away) While this is not always possible, it helps to get better measurements. It is also important to take into effect the terrain around you when taking a wind measurement.

Making the measurement with a Kestrel Weather Meter
:
For 1000, 2000, 2500, 3000, 3500: You may need to scroll through the list of measurements by using the left and right arrow keys.
For 4000+: You may need to scroll through list of measurements by using the up and down arrow keys.

Instantaneous Wind Speed: This is what is displayed on the Wind Speed screen. For NWS SKYWARN purposes, it is suggested to use either MPH or KTS as units. This is the “live” display of the data.

Wind Gust/Max Wind: This is the maximum 3-second sustained value. Use the left/right arrow keys to get to this value. (Note for 4000+: You need to turn this “on” to record max and avg wind by pressing the enter (horizontal bar) key on the max/avg screen. Do this before you begin reporting!)

Sustained wind speed: Scroll to the left or right to find this value. (For 4000+: this value is on the same screen as the max wind speed). For 1000-3500, this value is the average wind speed since turning on the unit. For 4000+, this is in the average since you have selected to record the value. Note, for NWS standards, averages winds are determined over a 2 minute period.

A note about the impeller on your Kestrel: The impeller on every Kestrel is replaceable. It is suggested to replace at least every battery change (batteries are have a life 300-400 hours of active use, depending on the model). The range of the impeller is 0.8 to 89 MPH for 3% accuracy (NWS requirement is 5%), and it will work up to 135 MPH (with less accuracy).

Temperature
Applies to: All models except 1000

All Kestrel models are equipped with quick-response thermometers that can are externally mounted from the case to give the most accurate reading possible. This patented technology allows you to measure temperature quickly and accurately.

Making the measurement with a Kestrel Weather Meter:
Navigate to the temperature screen (2000-3500: left and right arrows; 4000+: up and down arrows).

For air temperature, wave the Kestrel around for a few minutes. If taking from extreme environments (eg. 78 F in a house to 25 F outside) allow a few minutes for it to adjust. In cold environments, do not breath on the unit nor touch the sensor.

For water temperature, submerge unit in water. All Kestrel units are sealed to IP67 standards, which means it can be submerged at a 3 meter depth for up to 30 minutes. Unless you have goggles, it may be useful to use the hold function (on the 2000/2500/3000/3500) or manually capture the data in the data logger (4000+).

For snow temperature, place Kestrel in snow. As with when taking water measurements, the hold/data capture function of your Kestrel may be useful.

FYI: Water and Snow temperature are usually not useful to NWS Meteorologists, but are interesting parameters to measure. (Snow temperature is used by Olympic skiers and snowboarders to determine how much wax to use on their skis/snowboards.)

Other benefits to Kestrel units to keep you safe
Many Kestrel units can also display things like wind chill (2000+) and heat index (3000+). Barometric Pressure is another useful weather parameter to measure (2500/3500/4000/4500). Kestrel units are designed manufactured in the USA (in Boothwyn, PA) and are designed to be the best portable weather meters in the world! All units come with a 5 year warranty. Even after this period, any unit that stops functioning may be repaired or replaced with an equivalent model for a discount under the Customer Care Program.

“CEO” = Cross-training Exercise Opportunist

July 29th, 2010

This month our guest column is by Alix James, NK’s CEO. After practicing law in California for three years, she stepped off-track for motherhood and returned to working for NK in advertising and marketing. Eighteen years later, she’s worked in almost every department at NK and led many facets of the company’s growth. When she’s not working or traveling for NK, she can be found at home with her two teenage boys and four dogs, rowing her single or various team boats at Vesper, or on the back of one of her two horses trying to master the intricacies of dressage.

I’m guessing many of our customers face the same challenges I do in trying to maintain some semblance of fitness while also managing job, family and relationships.  I don’t claim to have discovered any earth-shattering secrets, but I thought a little bit about what I do and why might be of interest to others.

A lot of what I do now to train relates to the fact that I have done a lot of different sports and fitness activities over the past 30 (!) years.  I ran, cross-country skied and rode horses in high school, then was fortunate to walk on to the Yale women’s rowing team and work my way into the varsity eight my sophomore year.  We had a great year, winning the Sprints and losing only one in-season race.  I raced in the V8 for three years, and also learned to scull and raced the single and double at Canadian Henley, summer Sports Festivals and head races.  I kept rowing and sculling for a number of years after college, finally giving it up when I moved to San Diego.

In San Diego I ran and lifted a bit, then took up cycling. I joined a local cycling club for long rides through the hills, on the weekends, and on the weekdays grabbed a quick 17 miles up and down “the Strand” which connected Coronado to the mainland.  The local cycling track offered track racing lessons, so I learned to ride a fixed gear bike and competed in the Pursuit for a few years.  This was my first glimpse into the power of interval training.  Our cycling class was full of serious cyclists, who put in hundreds of miles on the road each week.  Listening to their training regimens intimidated me, but then we’d get on the track and I was faster than many of them.  It turns out that the intense interval training I’d done as a rower gave me peak power that their miles of steady state training did not.  Even on my quick rides up and down the Strand, I’d always work in a few sprints (okay, I’d jump out from behind after drafting off my husband and pass him in the last quarter mile).  Quality, not quantity.

Two kids later, I was up on Whidbey Island, Washington.  For the next five years, my athletic efforts were focused on riding my horse, hiking the trails with a BIG kid in a backpack, and “combat gardening” -  swinging a pick and digging holes in the glacial rock/dirt mix that made up my back yard.  I eventually made my way back to the Philadelphia suburbs, where I continued to ride my horse and took up Ashtanga yoga. (Yes, it’s possible to hurt yourself doing yoga.  My knees will tell you that.) I’ll admit, the core child-rearing years were not my fittest, but I kept moving and grabbing workouts when I could – a run, a lifting session, a swim at the Y.

About three years ago I worked my way back to the boathouse.  Sculling was always my preference, and the symmetry seems kinder to my body.  Whether in my single or team boats, I try to get on the water two to three times a week.  That’s not much, so I do everything I can to make every minute on the water count.  Over the last year I’ve been working with an excellent coach and a fun group, and that has made a huge difference to my effectiveness and focus.  I highly recommend hiring a coach occasionally if it’s available to you where you row.  Being back in the sport has helped me test and evaluate our products, and stay in touch with our customers’ challenges and needs of our rowing products.

Off the water, I ride my horse three or four times a week, run, and throw in the occasional CrossFit workout or yoga session for variety.  I’m reading Chi Running right now as I’ve learned that I can run much more comfortably with a mid-foot strike and a focus on staying light. When I start to plod, it’s time to stop!  CrossFit offers an approach that is intense, time-efficient and yields great full-body results.  At least I think it does, because it sure makes my full body sore whenever I do a “WOD” (CrossFit-ese for Workout of the Day).  You can get a glimpse of what CrossFit is about online, but to really learn the exercises correctly, find a local CrossFit box and go a few times a week during the winter.  Most places offer a reasonable per-class pay as you go approach.  With an understanding of the exercises and a minimal investment in some home equipment (kettlebells, plyobox, pull-up bar, abmat), you can get an amazing leg-toasting workout in 30 minutes.  I’m also a big believer in high-intensity interval training. Even when I’m completely out of gumption, I can usually talk myself into a few “Tabata cycles” of some exercise.  A Tabata cycle is generally 8 x 20 seconds on, 10 seconds off, followed by a minute rest.  Four times through that and you’ve worked 20 minutes at a level you just can’t sustain over a long workout.  Research has shown that these workouts generate the same aerobic capacity as long steady state, plus a higher VO2 max.

You can’t explore CrossFit without also encountering people discussing “Paleo” or “Primal” eating, which I’ve also worked towards over the last year.  The philosophy is to eat what our Paleolithic ancestors might have eaten.  Translated – lots of lean protein, vegetables and fruits.  Avoid grains and sugars of all kinds.  Enjoy healthy fats (butter included).  Dairy in moderation or not at all, depending on your personal makeup.  For me and most most people I know who’ve tried it, eating this way helps them stay lean, build muscle, and have lots of energy throughout the day.  I know all you mid-20’s four hour a day rowers out there can eat EVERYTHING that gets in your way, but believe me, that won’t always be the case.

And finally, I’m never afraid to give myself a break.  I figure if I can put in five quality workouts a week, that’s far better than giving up entirely because I’ve missed some days.

Observations from a Heat Wave

July 22nd, 2010

As the Philadelphia region is in the middle of its fifth heatwave of the year, we thought it would be a great time to track the conditions and compare two hot days worth of data. We used a Kestrel 4500 with Bluetooth on the tripod and vane mount, with the built-in data logger recording every minute. We left our setup outside during the hottest part of the day- from around noon till 4pm.

When doing these observations, we put the Kestrel setup on an island of grass out in our small parking lot. Now, most meteorologists and weather buffs may scoff at even the idea of taking weather observations that don’t meed the World Meteorological Organization’s standards (eg. temperature measured at 2 meters, wind at 10 meters, away from buildings, etc.), but we wanted to make observations of what the weather really feels like. Not the weather taken at the airport next to the tarmac, but the weather you feel when you go outside. Makes sense, right? This is why the Kestrel meters offer a more true environmental snapshot of exactly where you are- it measures the conditions right where you are- not miles away at the airport or another weather station hub.

A quick note about the thermistor (temperature sensor): at all angles, the thermistor stayed in the shade of the Kestrel unit. So while we did not measure the temperature within a Stevenson screen or within a fan-aspirated radiation shield, the temperature is accurate to what you would feel while outside, at that exact minute. This is why the temperature has so much variation on the charts below.

When first investigated the data, the first thing we looked at was what the difference between the two days was. We knew the first day was warmer, but that hardly tells the whole story.

Temperature for July 6 and 7

Recorded temperature during the afternoon on July 6 and 7, 2010 in Boothwyn, PA (just outside of Philadelphia).

In the graph, the darker line is the 6th and the brighter line is the 7th. At first glance, it looks like the temperature can really vary during the day. And in reality, it does. Most of the rises and dips in temperature can be explained by some passing clouds and winds (explained later). Even though the thermistor was not directly in the sun, when the sun went behind the clouds temperatures drifted down until the sun came back out. The high temperature recorded on the 6th was 105.5 F, while the high temperature recorded on the 7th was 104.5 F. Compare this to the local airport high’s of 102 and 103, respectively.

Now about that wind. I figured the wind had an influence on the temperature because to our west is a small woods area, and to the east is a large asphalt parking lot. I figured the temperature would become cooler with an easterly wind and warmer with a westerly wind. To investigate this, I took a day (the 7th) and plotted the temperature and wind direction on separate axes. The result is below, with wind direction in green and temperature in red.

Temperature vs. Wind Direction

Temperature vs. Wind Direction for a small period of time on the 7th.

Temperature vs. Wind Speed on July 7.

I noticed that there was a slight correlation between the direction and temperature, but it was not consistent. Also, I only took a small sample of the data where this effect looked better- in some segments of the data it was hardly noticeable. However, for times when the data did seem to align it was almost always the same. Temperatures rose with an Easterly wind, and temperatures decreased with a Westerly wind. After seeing this, I decided to compare the Temperature and Wind Speed during this same time period (below).

Now, the wind speed correlation seemed much more defined. As winds increased, the temperature reading dropped from the mixing going on in the air.

Looking closer at the data, I calculated the correlation factor for both variables with respect to temperature. (For those unfamiliar with correlation factors, -1 means a complete negative correlation, 1 means a complete positive correlation and 0 means no correlation at all.) Comparing the temperature to wind direction for the period graphed, the correlation factor was a measly -0.03. The wind speed had a much better correlation with temperature with a correlation factor of -0.69. For the entire day, temperature and wind had a correlation of -0.46 on the 6th and -0.50 on the 7th. Not an exact match, but a pretty strong observation that I wouldn’t be surprised to see during the summer.
