Callaway LR550 - Quickly and accurately measures the pin or hazard from up to 550 yards

Callaway LR550 Rangefinder by Nikon There's nothing quite as frustrating as hitting your club perfectly only to see the ball fall 30 yards short of the green. Enter the Callaway LR550 laser rangefinder, which quickly and accurately measures the yardstick from up to 550 yards away. The LR550, which comes in a striking yellow case, offers multiple range-finding modes for your convenience. The first target mode, for example, displays the range to the nearest target--useful when measuring the distance to a pin on the green with woods in the background. The rangefinder also boasts a continuous mode that ranges multiple targets in succession for up to eight seconds, so you can determine whether you have the right club to clear the sand trap or water hazard. Plus, targeting an object couldn't be easier thanks to the built-in reticle and LCD display, which combine to tell you when ranging is in progress. The LR550 is also noteworthy from an optical perspective. The rangefinder's 6x monocular, for example, offers such features as multicoated optics, long eye relief (with a folding rubber eyecup for eyeglass wearers), and a waterproof, nitrogen-sealed housing. The LR550--which runs on a CR2 3-volt lithium battery (included)--comes with a carabiner for easy access and a matching yellow neoprene sport sleeve with a removable travel cover.

Cartography: "The Mapmaking Process" pt3-3 1973 US Army

Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively... In cartography, technology has continually changed in order to meet the demands of new generations of mapmakers and map users. The first maps were manually constructed with brushes and parchment; therefore, varied in quality and were limited in distribution. The advent of magnetic devices, such as the compass and much later, magnetic storage devices, allowed for the creation of far more accurate maps and the ability to store and manipulate them ...

Infrared Radiation

Infrared RadiationInfrared radiation, infrared rays and electromagnetic radiation occupy the spectral domain between the red end of visible light spectrum and short-wave radio-frequency emission. The infrared spectrum range is provisionally classified into near, intermediate and far-infrared radiation. V. Herschel, a genius English scientist, discovered infrared radiation in 1800. Then it was proved that infrared radiation is in line with optical laws, therefore, its nature is similar to visible light. Similar to visible and ultraviolet radiation spectra, infrared radiation spectrum may either be made up of discrete lines or be continuous. This depends on infrared radiation source. Generally, optical properties (transparency, reflection factor, and refraction factor) within the infrared domain substantially differs from properties occurring within visible and ultraviolet domains. Many substances transparent within the visible domain turn out to be non-transparent in the infrared domain and vice versa.The Earth atmosphere attenuates infrared radiation as it disperses and is absorbed. Nitrogen and oxygen contained in air do not absorb infrared radiation. Though they attenuate radiation due to its dispersal. However, it disperses less than visible light. Water vapors, carbon-dioxide, ozone and other air impurities selectively absorb infrared radiation. Water vapors whose absorption bands lie within almost the whole infrared spectrum domain are the most intensive infrared ...
