It comes equipped with an easy-handling compass housing, silicon rubber feet for precision map work, luminous marking for the all-important night navigation, a large magnifying lens, GPS and map-measuring scales in mm or inches. Chinese unbranded knock-offs of Silva products are inaccurate, cheaply made and often fail to work too quickly.

L'unico neo rispetto ad un curvimetro analogico è che ha una rotella un po' troppo ampia e quindi sentieri/confini/fiumi troppo arzigolati non li pesca perfettamente.

But if I wish to measure a distance on the map now, while sitting in a tent, pub or hostel, I often simply use a length of thin cordage. A valuable piece of kit you will not want to forget when embarking on your next expedition adventure. This map spacing meter has a mini -metal handle that is convenient for grasping, lightweight and portable, easy to use.

Three Points of the Compass has taken a closer look at some particular makes and models of map measurers, including the Silva and Harvey measures mentioned above.The distance calculator will then display a measurement of the length in feet, meters, miles and kilometers. Set it according to your map scale and it measures your planned route in kilometers, miles or nautical miles. Their titanium Siphon has its faults, but these are mostly balanced out by simplicity, small size, light weight, robustness and performance. While a piece of cord or length of paper will simply measure a length, more complicated measurers can record in many units- multiples or sub-units of inches or feet, centimetres or metres, versts, miles or kilometres. In ogni caso in produzione sono cosi pochi e cosi poco accessibili che mi sento di dare 4 stelle complessive.

Beyond simple calipers, the earliest of map measurers, or opisometers, were very simple affairs indeed- little wheels on a threaded spindle that could be pushed along a line. It is a handsome measure and came with a range of interchangeable cards that provided differing scales. The card gauge is made of high quality metal and plastic, which is strong, wear-resistant, rainproof and durable.Lack of waterproof carry case / pouch which seems an obvious requirement given it's marketed to hikers and sailors. Not completely though- in 2018 compass maker Silva introduced a map measurement scale on some of their compass lanyards and in 2022 map maker Harvey introduced boot and shoe laces with measuring scales. It is difficult to read the labels on the "knobs" and it is even more difficult to read the units on the screen. Calculate the distance of your course so you can tailor your journey to the time you have available so you can get on with enjoying your favourite activities when you arrive. In recent years however, as digital mapping comes to the fore, they have very much fallen out of fashion.

I am one of a seemingly dying breed who still likes, appreciates and takes hard copy paper maps on trail. A Chinese knock-off of a Silva measurer was inaccurate but was able to offer measurements in quantums of feet, inches, yards, meters, cms. The Silva Expedition 4-360 Compass is an essential tool for advanced navigators, mountaineers, explorers and rescue professionals. I would prefer to switch the item off completely to save battery use as an item such as this sits in a draw for a good part of the year. The 'measure button' is too easy to inadvertently touch while measuring, thus stopping the measurement before time!We use marketing, analytical and functional cookies as well as similar technologies to give you the best experience. This compass is part of Silva’s Expedition series which has been the long-time global leader in compass accuracy, precision and durability. However, i may be wrong but perhaps always-on helps preserve the life of the screen for much longer where i like others experienced the failure of the screen to work after about 6 years of use.
