What is an altimeter?
Right Back to Basics is an altimeter means that changes in the level or as the pros say the measures - height. The easiest way to measure to measure the height as the air pressure around us, as we go up or down, change the air is thinner the higher you climb. Unfortunately, this change is very low (unless you have a jet!) And you need a highly accurate tool for measuring changes in air pressure from hikers, or evendownhill skiing. Until recently the only way was to do this with a very sensitive mechanical device that is too large, delicate and expensive for the average Joe to wear. Then, the electronic measuring devices have been for aircraft - but they were incredibly expensive, very exotic. And then came the wonders and miniature electronics to shrink until they fall into a normal watch! Now everyone can have one.
But the changes in air pressure over time, is not it?
Yes, it isago, but not enough for the altitude too vague and a little 'attention you can actually see the changes in air pressure and to get a picture of the time. In other words, you can create your own weather forecast on your wrist!
But I want to do with an altimeter-watch?
It depends on what you do with your life, but just imagine how many of today's action sports up involved ... and then back down. Make sure you know how much you have climbed from belowthe hill, the total gain for the day on a mountain bike, how far you have a hill down ski'd - and how much time you have taken. You can go next week to try again and do more, faster! There are other things you can pin point where climbers are - if you are on a knife-edge ridge, if you know the size you can read a summary on the map and determine the location. If you are camping in the desert, the air pressure can watch during the night and see if tomorrow will bring the glorious day you areHope! Whatever you do the tour cycle skydiving, would not be good, you just know something more about where you are and what have you done?
Ok, I have one, as I use it to measure the amount purchased?
must get the basics down dead easy when precision is not a matter of life or death, or if you are only interested in relative change in height (relative change is the difference between A and B, not the actual height of point A or B), then read or change your height to height,directly from the dial - no truth. Zero it (or put the next shape on the card) at the bottom and read your climb up, and easy with these great clocks with an accuracy of 1-2 meters. While not equal to zero, the elevation is approximately correct for a given location (eg 10 m) and will be to gain height with an accuracy of 1-2 meters.
But the specification says that the height measurements with an accuracy of one meter?
Well, what do they meanis to measure the variation in height of one meter, the absolute amount of precision you callibrate measuring instrument and the climate influence the air pressure to maintain the accuracy callibrate even if it is possible all day. That sounds like a chore, it is not. All that is, whenever you reach a point where you know the height, for example on top of a mountain, a lake or other place where you can read the height of a card,Reset the actual amount of the Clock. They take a few keystrokes and a few seconds. Even if you could tell accurately when you need the cloud to 2,000 m in the Cairngorm plateau, you just do this every couple of hours at most. I have stuck to the shore, and was perfectly meters on the summit of Ben Assynt more 4 hours later!
And time?
Now, set the clock on the Barometer mode and check the air pressure at the moment. If its high, and will 1020Mbarlikely to be dry. 980Mbar and down, and will probably be gray and wet. I say probably because it is not foolproof, but it's a pretty good clue. If you look at the weather over time, for example during the night, you will fall on the trend (on the small clock greaph) shows to see if the pressure increases or maybe just stay the same. In general, if the pressure drops, it's worse when on, the sky is unlikely to compensate. It takes a while 'forTalent, but soon you have a good idea of what's happening around you. If you see the Baro and plummetting to 980, well, maybe it will be back to the bike shed and do your colleagues a round table to talk about how good it was last week. If you are a canoeist - perhaps this weekend will be a great little water!
Yes, but she said the height affects the air pressure and air pressure affect the weather - how do I know what it is, the readings?
Well, aadvanced users! You're right, they influence each other, and the altitude affects more than just the weather, so if you go up and down a bit 'hard enough to filter the time, but you can do it. The main thing to keep in calibration when the weather or the amount of important - to maintain the calibration. In general, the clock on the map calibrated height, this is definitely the height is always correct. But if you calibrate, stop and think for a minute, the clock is reading low, orhigh. If it is too low to read, is good news, because the air pressure has increased recently calibrated - remember - more pressure means less height - so the reading noted down. If the height is of high value, the opposite is true, decreased blood pressure - could be worse than the time to come. The amount you must learn something by changing the clock - one or two meters: time is very long, 10 meters and it is better to watch. To get a rough idea of changes in pressureabout 1 mbar for each 8 m high, so if you 900mbar at 800m and the atmospheric pressure at sea level is 900 800 / 8 = 1000mbar. If you are a die real time, you can use the following table to estimate the atmospheric pressure at sea level, the readings of altitude and barometer on your location. Remember - this is an estimate, many factors affect the actual pressure of the air - Calibration and keep your eyes peeled!

And if you have a compass!
Some of them do not have the best military marching compass, but do the job.The hands are usually small, but with the illuminated display you can make enough to check your course and there's the wrist, it is always immediately available and will never see on your pimples. Hold the compass for the practical decisions of real sailing, but check your watch often you need to stay on the line.
The final image
At the end of the day, watches High are just another tool, you can simply enjoy a serious aid training, or actually his assDeep stuff. If you intend to use it seriously, you have to practice and maintain control against all other inputs you have in your environment. Keep it visible in good weather on the wrist, in case of bad weather put them on over my coat - it's waterproof! A good navigator uses all his tools together and so will be on site when one of them is he misleading. Personally, my Alti-Watch (I'm on my second!) Saved me a severe pain and kept me out of the ground hurt more than once, I'm wearingevery day and watch the time so you know if the bike to work or not!
I can not say that you should get one, but if you spend time outdoors that I will use it, and at current prices, why not just try. Typical is his preferred choice Suunto Core, which are reliable and accurate
Have fun but keep safe out there!
