Brunton ADC Pro - A short review

It didn't take a long time, on the course of my present professional occupation, for me to realize the need of up-to-date meteorological data.
When I was at sea, particularly during my period as a Deck Trainee (cadet) and also as a Second-Mate, some of my responsibilities were related to meteorological duties. Besides chart work (updating the navigation charts and correcting them), the correction of nautical publications, the care for the ships infirmary and a few more responsibilities that we "lower" deck-hand people have to perform in order to learn the trade and subsequently transit to a higher level of enlightenment, I had also at my care the nautical instruments. They were not so many, to be honest. Just enough equipment to allow us to measure the basic weather parameters: air temperature, atmospheric pressure and humidity and wind direction and speed. To achieve this goal, a typical on-board weather station generally comprises one atmospheric thermometer, a barometer and a barograph, a hygrometer and one anemometer Commonly the hygrometer is replaced by the wet and dry bulb thermometer, less expensive and less prone to calibration errors. The only difference between the two is that instead of a direct reading (on the case of the hygrometer), you have to calculate the atmospheric RH by reading both data values (wet and dry) and compare them in a standard chart, normally placed on the instrument itself.
Far from being useful only at sea, a good knowledge and interpretation of these elemental atmospheric parameters can be quite practical also in our daily lives, easily transforming us in amateur meteorologists.
Well, at home, near the technology and information, this knowledge might seems redundant. After all, if we need to know the weather conditions for tomorrow we just have to read the newspaper. Or listen to the TV. Or check the web.
However, when you are far away from civilization, either at sea or on the high peaks of our Earth's highest massifs - in a word: away from that easily digested information - a general meteorological knowledge is not only mandatory: it can actually save your life.
Naturally there's only so much you can learn when you look at the skies, regardless of that visual information being already quite useful. To be more effective in weather interpretation, you have to actually know, with the best possible accuracy, those elemental parameters I've said before.
"Red sky at morning, sailors take warning;
Red sky at night, sailors' delight."
There's only so much you can predict by using visualization combined with the old adages...
In the picture: peaceful red-painted evening sky over the high peaks of Madeira. A clear prognosis of the next day's weather trend.
 
To reach that higher level of enlightenment, you will need instruments that give you answers to those parameters we've spoke about. Combine them altogether in the same place and what you get is a meteorological (or weather) station. If space and weight is no object, as it is not on the bridge of a ship or on the deck of a fire lookout tower, you can have the luxury of a fixed station. On the other hand, if you are hiking or trekking in some remote wilderness, you'll thank the Lord for the miniaturization.
Because the portable (or handheld) weather stations are the answer to our weight and space limitations.
These products give you the chance, today, of taking to the field a more or less accurate forecasting equipment that will vastly improve your knowledge about the climate, therefore helping you to make a proper judgement of the weather surrounding you.
And I emphasize the "more or less" comment, because, like most instruments, its accuracy is directly dependent of two main factors:
First:
You get what you pay for. As a rule of thumb: the more expensive the equipment the best it is.
Second:
You have to know what you are doing. You have to have a clear understanding of the equipment you own and also be able to interpret the data it gives you. To achieve both, you have to read its technical (or user's) manual and be proficient in meteorological knowledge.
From the several instruments existing on the market, I've chosen the Brunton ADC Pro. For two main reasons: it has the qualities I need, with the best (less) price, from a known brand.
Although I clearly doubt if this equipment is really made by Brunton - if you look around, you can see the exact equipment on sale from other makers, like the Swedish Silva - at least a well known label should give us some confidence on the product.
I won't go too far on the equipment's description. For that, you'll have plenty of info on the web. It's suffice to say that, for outdoor adventures, as long as you have an equipment that gives you barometric, air temperature, atmospheric humidity and wind speed readings you are well equipped. All the remaining functions are just software power embedded on the equipment. Just a way to make data more easily readable. Altimeter? The altimeter data is directly related to atmospheric pressure, hence to the barometer. Atmospheric pressure decreases roughly 1 mbar for each ten meters of altitude you climb. So you see, with a good, calibrated, barometer, all it takes is some math. Wind chill? Wind chill is a relation between air temperature and wind speed. There are tables for that. The software embedded on the equipment just makes the calculations for you. Get the picture?
Regarding the Brunton:
Well, I guess nothing is better to test an equipment than time. We are a society of easy consumption. And, nowadays, when we buy something we don't expect it to last. Although I understand that, somehow. This makes sense worldwide, since there are so many mouths to feed, dependent on the factories production. Brands all over the world should, nevertheless, be more proud of the durability of their products. Invest on it. Compromising durability is, ultimately, a compromise in quality.
Using this product for more than six years, on my professional life and occasionally on my leisure time, I can tell you that time is now taking its toll and this equipment is far from being great.
The Brunton ADC Pro is far from being a great handheld weather station. We can call it "competent", just for the sake of courtesy. After six years of use, always with the equipment protected - except in observation times - as you can see by the absence of marks on its screen, the Brunton accuses its age. The rubberized cover is collapsing and so are the push-buttons, which are becoming sticky, due to rubber deterioration. Not acceptable. The impeller, which is basically an half-sphere encased in the instrument's structure is now too loose. Under pressure from strong winds, it now closes by itself, difficulting readings.
The device has one IR port, to transmit data to a PC. For that, you have to order the IR USB Data Transmitter (eg: Amazon) and install the respective software on the computer. I have also to tell you: almost nothing on this equipment is user-friendly. Menus and sub-menus are not that intuitive. If you want to use it at its fullest bring the (at least) simplified manual with you. The PC software is simple and (as far as I know) it's only accepted up to Windows Vista. Beyond that you are on your own. Synchronizing PC with the ADC Pro is also not easy from the start. It takes some trial and error. To the best of my knowledge, after all these years the software was never updated. It's still on its original form.
As I've said previously, the software is very simple. No interaction with the equipment. It just receives its historical data, nothing more. Limited customization is possible.

To replace the battery (one CR2032 3 Volts), the cover is somehow stiff - probably due to the sealing o-ring - forcing us to use the tip of a knife's blade (gently) to remove it. Notice the impeller's half-sphere on its closed position. Missing a lock for the open and closed impeller's position. As you can see, the rubberized cover is nearly gone, giving the equipment a not-so-good looks.
 
Positives:
It's accurate. Barometer and thermometer can be calibrated up to the tenths of the units. And tenths of units are also shown in the anemometer and hygrometer readings (sadly both these two values cannot be calibrated). From observation (comparing it with ship's stations) I've noticed often variations of up to 2 mbars on the barometer measurements and up to two degrees Celsius in air temperature. We can accept these discrepancies since the equipments on board are not exactly reference instruments. Just make sure, when taking measurements, that you leave the equipment steady for a couple of minutes, preferably on the shadow, for the best accuracy possible. The sensors are so sensible that, if you move or lightly shake it, changes on barometric and altitude reading are almost immediate. If we follow this rule, we can accept the precision given by the manufacturer as honest values.
 
Brunton ADC Pro reviews:
 
Comparison of the different ADC's:
 
Bottom line:
If your are tight on a budget, this equipment should suffice your needs. On the other hand, if money is no problem or if you are looking for a more durable piece of equipment, built for more intensive use (and paying for that the price of twice the cost), you should look at Kestrel. Good luck.

Echoes of Switzerland

On 1998, during my InterRail Winter sojourn around Europe, I passed though Switzerland on my way to the Eastern countries. In a nation built over a dramatic orography, Swiss citizens had (and learnt) to be resourceful in order to occupy every inch of useful land available.
When the train left the station and the apparent safety of the green valley below, the alpine landscape unfolded before me and so did the human ingenuity to conquer it. The conventional train, unable to vanquish those steep gradients, was a black spot on the faraway station left behind, while our present transport, a cog train - similar to the former Caminho de Ferro do Monte, and wise replacement of the previous one - was leading me to the alpines meadows of the Kleine Scheidegg, right below the monstrous North face of the Ogre and well above the tree line.
On the way up, Milka look-a-like cows and farmers were both taking care of their own private businesses, two steps away from the nearest one-thousand-meter precipice with an easy-going attitude and tranquillity as if they were taking an evening stroll along the Lido Promenade.
At the time I thought this was as extreme as we humans could be. Well, as we all know, where there are humans (or cognitive animals, for that matter) there are also boundaries to be broken. And there are almost no limits to engineering.
On the particular subject of men versus orographic environment, Madeira is, hands down, our little Switzerland.
With a volcanic substrate carved by millions of years of erosive forces, Madeira's landscape is as dramatic as it can possibly be.
And also here the human inventiveness knows no limits in order to overcome the difficulties.
You need to carry heavy weights over a steep mountain trail, suitable only for people or pack animals, but you have to do it with some kind of motorized transportation?
Well, there's a solution for that too!
The reforestation operation taking place by these days along the mountain trail heading to the island's highest peak is being helped by a mechanized assistant, rarely seen in Madeira's "adventureland":
The Kubota KC110H, a small crawler dumper, built for restricted spaces, although not pretty, looked quite effective for the task.
Climbing the steps on the trail seemed to be the most delicate manoeuvre for the machine. Well, if you cannot ride it, you can always walk along with it. Just like motorbiking. On these particular parts of the trail, the additional grip given by the rubber caterpillar tracks makes a difference. It's hard to imagine that a cargo-carrying machine can advance through this terrain. Naturally, steady hands from the driver are paramount.

From Pico do Areeiro to Pico Ruívo - PR 1 - The new route

As I mentioned in an earlier post, the trail between the two highest peaks in Madeira is open, since last April, for traffic, following the repairs that took place after the landslide. Today, six months after the conclusion of the work, the opinions regarding its effectiveness diverge, being most of the hikers skeptic about the durability of the chosen option: the construction of a whole new section of the trail, instead of repairing the damaged one. Many believe the new route will not survive the Winter season approaching and the consequent worsening weather conditions. Time will tell.
Regardless of the decision's technical questionability, the fact is this was a strenuous work for a group of construction workers, since all the materials, due to the remoteness of the location, had to be carried by human portage, including an eighty-kilograms generator.
The photos below, taken one day before the official public opening, gives us a vision of the structures built in-situ to surpass the terrain obstacles.
Picture above:
On the afternoon of the last working day, a team of surveyors and construction workers retreat from the newly-finished trail and head on to Achada do Teixeira, ending an intervention that lasted nearly four months.

Tamrac Adventure 10 backpack

The Adventure 10 is a mixed hiking and photography backpack from Tamrac. This means that, contrary to the traditional photo backpacks, which only function is to carry and protect photographic equipment, this particular pack includes in its design an additional separated top compartment suitable for the transportation of items normally needed by nature excursionists, e.g. additional pieces of clothing, food, hiking equipment, etc.
This versatility makes it the right photography backpack for any hike that takes you farther from the parking lot, giving you a higher autonomy in anything that exceeds a morning or a afternoon walk.
I'm growing rather fond of my Tamrac Adventure 10 nowadays. Why? Well, in Summer time, here in Madeira, there isn't much we need in the hills except a couple of boots in our feet, a hat, a t-shirt or a polartec fleece and a pair of shorts. For food you carry a couple of power bars or snacks and for drinking you just need a filled up 1 liter water bottle. That's all. During that gentle season, my favorite photographic pack is the trusty Lowepro Inverse 200 AW belt pack. It has plenty of room for a Pro (D)SLR, together with a couple of lenses and a flash, and can also carry the needed food and drink.
In the Winter season, now starting, it's another story. The weather becomes unpredictable in Madeira's highest peaks and trails. The natural excessive humidity in the air, the sudden rain showers, the stronger winds and the low atmospheric temperatures, all conspire to change a peaceful walk in the hills into a living hypotermic hell in a very short notice. In those moments the difference between panic and self-control is proper equipment and preparation.
 
For the actual preparation you have to start working months before. You have to know your trade. And being an experienced hiker, as in all human activities and endeavors, requires commitment, dedication and time. Grouping the necessary equipment is easier. You don't need to be a PhD for that. You just need to follow a check-list taken from the web. Using it properly, however, requires you to reread the above paragraph.
Well, the first piece of equipment for us nature photographers of the Northern Hemisphere facing the arrival of Winter might as well be this dual-purpose backpack, that will allow us to carry, besides photo gear, all the other items to make our walks in the wilderness a bit more comfortable. A rain poncho or a Gore-Tex jacket, a all-weather cover for the backpack itself, additional dry clothes, a flash light, a mobile phone, a compass and charts or a portable GPS - don't forget a whistle and a signaling mirror - are all items that I stow religiously on the Tamrac's top compartment.
If I can find a negative detail on the Tamrac Adventure 10, this is, without doubt, its harness, back padding and straps system. These are quite simple and - it doesn't really matter how much you try to adjust them - you'll have a hard time trying to equilibrate the pack on your shoulders and back. Not nearly in the same league as the Lowepros. But for the luxury of an internal aluminium frame, you have to be prepared to pay twice the price. As in many things, you get what you pay for. Zippers are also far from perfect, being a little stiff and the opening of the top compartment could be better engineered. Besides that, this particular pack doesn't bring an all-weather cover. So, if you are planning hikes in rainy conditions, you better buy one on the E-Bay, from the many Chinese sellers out there. Four or five Euros should do the trick.
The 17' laptop compartment (visible here, near the back padding) is a must, and, due to that, this backpack quickly became my all-around carry-on air travel bag, allowing me to bring on the cabin all the valuable photographic and personal items that, otherwise, I'd have to send to the hold.
Two mesh pockets on either side allow for a small tripod transport or a water bottle. Along the pack's body and straps there are several points for connection of accessories of the M.A.S and S.A.S lines, also compatible with several accessories from other makers.
Bottom line: if you want a dual photo backpack that does the job, without damaging excessively your bank account, you will not make a mistake. The Adventure 10 is a reliable piece of equipment, with plenty of load capacity, without the bells and whistles that characterize more expensive options. However, if these bells and whistles are important for your needs, you should look nearby, on the higher specialized Lowepro competition.

Levada dos Cedros - P.R. 14

The Levada dos Cedros has one of the most handsome sources in all the Madeira's levadas. However, as strange as it may seem, this path is not as visited as its nearest neighbours, in Rabaçal valley. Hidden deep in Fanal, this hike is, nevertheless, a pleasurable one, taking you deep into the Laurissilva forest.
The departure point to Levada dos Cedros source, nearby the ER 209 (Regional Road).
 
Description:
Departure position:
Lat:   32º49'33"N
Long: 017º09'29"W
Altitude: 870 mts
Source (arrival) position:
Lat:    32º47'57"N
Long: 017º08?39"W
Altitude: 910 mts
 
Distance: 5.4 kms
Time:       aprox. 1h30m
The round hike (from departure to departure) will take you about three hours on the trail and nearly eleven kilometres of walking.

The North Face Dhaulagiri II GTX - The perfect all-around hiking boot?

Ask any hiker which part of the equipment he values the most and the vast majority of them will mention the boots.
The reason for that choice is, we all know, quite simple:
Hiking, naturally, presupposes walking and for that you need your feet. Without adequate protection, they won't take you far.
In the end, as in many options in life, choosing the right hiking shoes is a matter of personal taste and always subjective.
Furthermore, if we try to separate and classify things by makers and nationality, we all get more confused in the process. We could argue that the best shoemakers are Italians. An in a way we may be right. Therefore, in terms of quality (at least), we could expect a good quality product, if bought from an Italian company. Brands like Scarpa, La Sportiva, Asolo, Crispi or Garmont - to name a few - became over the decades synonymous of quality handcrafting.
However, when, nowadays, we check their tongues, we hardly get surprised to see that these shoes are not made in Europe anymore.
So much for the European production and quality, if there is still any.
Increasing our doubts, instead of calming us, the market is now being invaded by shoes made by companies that, until recent times, had no tradition whatsoever in the shoe-making industry.
Millet, The North Face, Karrimor or Salewa are just a few, among several companies, that are presently diversifying their catalogs and including in them lines of shoes and mountains boots.
Seeing a clothing company designing shoes should gives us the same peace of mind we would get from a luxury automobile company attempting the construction of jet engines, right? Well, as the latter proved, there is nothing wrong with that.
Today I have the proof of that. Three years ago, while looking for a pair of all-around hiking boots suitable for the Madeira environment and wouldn't destroy my wallet, I gave a moment of attention to the North Face Dhaulagiri II GTX. I had a few guiding lines of what I thought the right hiking boot for Madeira should be: light construction, preferably in a mixed of leather and synthetic materials, hence breathable and simultaneously waterproof (meaning a Gore-Tex membrane), a rubberized toe cap and Vibram rubber sole. I discarded the full-leather construction because, in my opinion, although being clearly the best in impermeability, they are too hot for the Madeira gentle climate. The handful of days per year we have in the island's highest mountains sub-zero temperatures and snow that could justify an all-leather boot are not enough to justify walking with the feet soaked in perspiration the rest of the time. They are also harder to maintain, requiring more complex care.
Having previously used hiking shoes from The North Face and being quite happy with them, I decided to give their boots a try.
First of all, I've noticed that they were with a very large discount. Which isn't always a good sign. Second, the opinions on the web were not that unanimous. Some were saying the boots were great, the others said they were amongst the worst. Well, all I can is to give you, also, my two cents worth on the subject.
And from day one I couldn't be happier with the choice I've made. The boots fitted my feet like gloves. Wearing a 7.5 UK size on the hiking shoes, I choose to buy their boots in 8 UK - half size bigger. I do not regret the decision. The feet are more free inside the boot, without excessive play. No blisters to account for.
The North Face Dhaulagiri II GTX hiking boots. These boots from The North Face ended up being a good surprise, lasting more than two years, after continuous use and abuse in the mountains of Madeira. 86 UK Pounds well spent.
The worn out Vibram soles of the Dhaulagiris. After two years of continuous use, this was, not surprisingly, the first component to collapse. A second (new) pair is already at home. To replace them.

Shoe-making of another era.
Twenty-six years ago, when I embraced mountaineering, we could notice an informed mountaineer (not necessarily a good one!) by the boots he or she wore. Contrary to the present diversity, during those days mountain footwear was categorized for their specific use: low mountain, medium mountain and high mountain. There were almost no hiking shoes (people used tennis shoes for all uses that did not require a stronger footwear) and the modern and so popular approach shoes - a mix between light hiking shoes and rock climbing shoes - were yet to be invented.
In those days, a pair of good quality mountain boots - according to the books - had to have the following characteristics: a Vibram sole, full leather construction (with leather preferably of three millimeters thickness), the minimum of seams on the upper body (meaning using the minimum of leather pieces for the whole boot), the sewing of the sole should be made with a double (preferably triple) seam and the shaft should be high enough to protect the ankle movement.
The rubber soles should be flexible for low mountain use, semi-flexible for medium mountain (suitable for use with strap crampons) and rigid for high-mountain (recommended for use with automatic crampons).
Regardless of their final use, these boots were more or less built with the same technical quality. And we expected them to live a lifetime.
My Dachstein medium mountain boots, reaching now a quarter of a century, have already many hundreds of kilometers of mountain trails under their (original) soles. They just need to be washed once at home, left to dry in the shadow and then greased with Dubbin.
So far, they lasted for twenty five years. And since I don't use them quite so often anymore, with the same proper care, they will probably outlive me.
Well, those days are gone. Except a few high quality models, no shoemaker makes a boot or a shoe to last. The ergonomy in the products, propelled by a better knowledge of body mechanics, evolved, as the technicality of the materials used. But the durability was compromised on the process. For instance, where once you had a flat or straight Vibram sole glued to the insole (allowing for replacement), you now have the same Vibram material on a vulcanized sole with a sinuous and exotic profile, irreplaceable. 

Why am I telling you all of this?
Well, because if you are a little bit complicated - just like me - you still expect, presently, to buy a pair of mountain boots that lasts for your entire career among the peaks.
Forget it. Mountain footwear is becoming more and more similar to any other consumption product. It is supposed to have a lifespan of a couple of years and then you send it into the dumpster. As Sam Rockwell wisely pointed out in Iron Man 2: "Don't get so attached to things, learn to let go!". You just have to accept this as an actual fact, expect the equipment to perform faultlessly during its entire lifetime and move on to another one in the nearby future.

So, as long as you admit this - the temporary and finite condition of any present good - any mountain footwear that you buy today should give you miles of pleasant hikes in the nature. As long as it fits your feet.
