Product DescriptionX10 Military GPS WatchAmazon. com Product DescriptionSmall and lightweight, the Suunto X10M wrist-top computer watch combines an altimeter, barometer, compass, and GPS navigator, making it a terrific companion for outdoor enthusiasts of all stripes. The X10M–which builds on Suunto’s decade of experience in creating cutting-edge outdoor devices–stands above most other wrist-top computers thanks to its improved, faster GPS fixes. Even under heavy foliage, you can use the X10M to plot your treks, navigate to a certain spot, or get back to your car, all while keeping your hands free to hold a hiking stick or water bottle. Once back at home, you can share your treks on Google Earth, or use the Suunto Trek Manager PC software to create new routes and plan new journeys. The Suunto X10M also includes a built-in altimeter, which displays your current altitude and your vertical ascent and descent rate. Accurate to within 30,000 feet, the altimeter is an extremely valuable tool for mountaineering, backcountry skiing, and wilderness travel. The altimeter contributes to your excursion in several ways. If you’re standing on or near an obvious geographic feature, such as a ridge, trail, or creek, the altimeter can alert you to your current elevation and help you find your position on a topographic map. Similarly, if you plan on climbing a slope to a certain elevation and then traversing, the X10M can help you stay on course. And, of course, the X10M captures all your altitude information in its integrated logbook, making it easy to analyze your performance when creating a training routine. The Suunto X10M watch includes an altimeter, barometer, compass, and GPS navigator. The X10M’s barometer, meanwhile, measures and records air pressure to help you predict changing conditions–from sunny skies to hair-bending electrical storms. The barometer helps you decide whether to bring a soft shell or rain shell jacket when the skies look ominous, or even when to high-tail it back to the car. In general, low pressure brings inclement weather, while high pressure brings stability and clear skies. If you’ve arrived at camp and notice the pressure starting to plunge, it’s probably a good idea to secure the tent and crawl in. Likewise, if you’re on a climb, it would be prudent to find shelter and retreat. Even at home, the X10M’s barometer can look beyond office walls, skyscrapers, and nearby hills to help you plan for upcoming activities. And no outdoor watch is worth its salt without a digital compass, a great tool for keeping track of your direction while skiing, hiking, or exploring a new city. Simply point the top of the watch toward your intended destination and lock it in. Other features include an Activity Mode that records your speed, distance, and altitude information, along with any memory points you define along the way; a Track Back mode that guides you back the same way you came; a long-lasting battery; up to 50 routes, 25 tracks, and 500 waypoints; water-resistance up to 330 feet; and all the standard watch functions, including a 12/24-hour display, a stopwatch, a calendar clock, and three daily alarms. As with all Suunto wrist-top computers, the X10M carries a two-year warranty.

Being an engineer with an inventive turn of mind, he discovered and patented the production method for a much steadier needle, better readings, and a new level of accuracy. By 1950 the company was exporting compasses to over 50 countries around the world, including Canada and the United States. In 1952, Helsinki was hosting the Olympic Games, and the torches carried to light the Olympic flame were Suunto products. The next step was improving the stability and accuracy of marine compasses. The first marine compass, the Suunto K-12, was launched onto the market in 1953. In 1957, Suunto started manufacturing hypsometers, which measure the height of trees. In the 1960s, the compass range grew further and Suunto introduced its first diving compass–initiated by the divers themselves. A British sports diver attached a Suunto compass to his wrist and found that the device also worked underwater. Thanks to his feedback and initiatives, the new business category was found. Suunto’s exports and business grew steadily and Suunto then focused on combining its strength in precision mechanics with new skills in electronics. Accuracy, reliability, and ruggedness have been Suunto’s key values from the very beginning of the company history. Today, Suunto is a leading designer and manufacturer of sports instruments for training, diving, mountaineering, hiking, skiing, sailing, and golf. True to its roots, Suunto is today the world’s biggest compass manufacturer. Prized for their design, accuracy and dependability, Suunto sports instruments combine the aesthetics and functionality of watches with sport-specific computers that help athletes at all levels analyze and improve performance. Headquartered in Vantaa, Finland, Suunto employs more than 500 people worldwide and distributes its products to nearly 60 countries. The company is a subsidiary of Helsinki-based Amer Sports Corporation with the sister brands Wilson, Salomon, Atomic, Precor, and Mavic.

Green Laser Pointers Applications and advantages

Luigi Castagna asked:

Green laser pointers were first commercially sold in the year 2000. They operate at the wavelength of 532 nm. Laser diodes of this wavelength are not available so the green light is obtained by the use of “DPSSFD” laser technology.

The process:-

A very high-powered Infrared laser diode working at 808 nm pumps a tiny block of Nd: YVO4 that generates light at 1,064 nm. This feeds a potassium titanyl phosphate intracavity frequency doubler crystal that produces green light of a visible 532 nm wavelength. High-powered green lasers use lithium triborate instead of KTP.


An infrared filter, which is behind the mirror completely, removes the radiation of infrared spectrum from the output beam. In order to reduce cooling problems and prolong battery life, some green lasers operate in pulse or quasi-continuous-wave (QCW) mode. The Class III a laser product gives an output power of 5mw. This is the one of highest-powered street legal laser. Some green lasers even have an output of 10 mw, which has a range of 20,000 feet in darkness. Some even have a 3-second delay feature as these are high-powered lasers and can blind a person. Some laser point extenders are also available. They work by using lenses to minimize the beam spread of a laser. Its price starts from 55$. Majority of them have a life of around 3000 hours.


Green lasers can be used for a variety of roles. They can be used as pointing devices. The ability to form a continuous line in the dark is an added advantage; this has lead to its usage as rescue lights as it can be seen from miles away. It as been used for laser light shows. It is also used for sky gazing as a person can pinpoint a star by using the green laser. It can also be as laser pointers for guns, rifles. In the movie Alien vs. Predator it was used as a pointing device on some G36k carbines.


The green laser has many advantages. It is fifty times brighter than a red laser because of which it can be seen from miles away, this helps in being rescued if a person is lost. It can also be used in high-tech weapons for aiming purposes. Because of its high range, Green laser pointers can be equipped in different kinds of weapons. High and low temperatures do not affect the performance of Green laser pointers so in case a person is lost in a desert, he can still use Green laser pointers to call for help, in other case, even if a person is lost some where in mountains all covered with ice, he can still use it.


Due to its high power it can permanently damage a person’s eye. As it can form a continuous line of light that might reveal a person’s position so it cannot be used in stealthy operations or by SWAT.

Green laser is quite awesome but it should be used carefully.
