The Military Telemeter

The Wndsn Telemeter ("Telemeter") is a low-tech observation instrument for measuring distances and angles with the naked eye. Developed in 2016 the Telemeter is a distance and altitude nomograph that enables the measurement and calculation of distance, dimension, position, and slope.

The Telemeter combines a thousand years of military technology, surveying, and navigation and is used to help navigate with known landmarks or astronomical features, to check values determined with other tools or in situations when other methods fail or are not available; the Telemeter works where laser rangefinders fail. The Telemeter is a multitool for makeshift navigation, for training, as a visualization tool or for comparing the results of other instruments, which can be used anywhere regardless of external technologies and belongs in every recruit’s, instructor’s and survival kit.

  • Front side: rangefinder with built-in graphical computer for determining angular sizes.
  • Back side: degree and inclinometer scale for determining slope and elevation as well as for calculating sine, cosine, and tangent for a given angle.

All the necessary calculations can be called up directly via the string.

Here is an annotated overview of the available products and their intended use.


Telemeter for determining distance and height

  • The double-side matte-black NATO-MIL Telemeter (qTM-NATO) is specifically designed for military use; this model measures in NATO-MIL. This model offers distance measuring functions as well as an inclinometer, a coordinate scale (1:25k) and a Quadrant for trigonometric calculations.
  • A transparent single-sided Telemeter (nTM) is available for use at night or in adverse light conditions; this can be equipped with a mini glow stick to read the scales in the dark. This model offers only distance measuring functions

For Instructors

  • For instructors there is the special, enlarged instructor Telemeter (wqTMx2) for simplified showing and demonstration.
  • The comprehensive field manual (NATO-MIL FM EN).

Calculators for converting units

  • To convert units there is a calculator (MMC) that can convert values from MIL (or MOA, from a graticule or reticle) directly into distance.
  • There is a training model (GMC) for determining grouping, which can convert the diameter of a grouping circle directly into MOA.

Benefits And Areas Of Application Of The Telemeter

  • Determine position indirectly using landmarks.
  • Record and recon routes.
  • Calculation of driving and crossing times.
  • Assessing ranges and distances.
  • Calculate target accuracy in training and convert MIL and MOA to distance.

With the Quadrant Telemeter you can measure angular values and determine or calculate distances, heights or depths. You can also calculate the sine, cosine or tangent of a given angle. Here are some practical tasks Quadrant Telemeters are used for:

Land Navigation

  • Determine the distance to an object with at least one known dimension.
  • Perform a resection trilateration by determining the distance to two known landmarks.
  • Perform a resection triangulation by determining a distance and a compass bearing on a known landmark.
  • Measure the height of an object using a vertical angle and distance (by measuring or pacing), using the built-in trigonometry.
  • Measure the height of a lookout point based on a known height of any object.
  • Measure the length of a tunnel, the height of a chimney, etc.
  • Measuring the angle of a slope.
  • Measuring the depth of a well.
  • Find a vertical with the plumb line.
  • Show deviation from true vertical or horizontal.
  • Use of the Quadrant as a protractor.

Surveying and Reconnaissance

  • Calculation of distances with the nomograph from angle values that are determined, for example, with devices with a reticle.
  • Determining the angular size of a body taking into account its dimensions and distance.
  • Mapping terrain.
  • Measure angles of inclination and slopes.
  • Measuring the elevation angles of objects that are not accessible for direct measurement.

Trigonometry

  • Calculate sine and cosine angles.
  • Calculate sine and cosine as ratios.
  • Calculate tangent, cotangent and arctangent.
  • Calculate angles from sine and cosine and tangent.
  • Multiply and divide angles.
  • Visualize the unit circle with the Quadrant.

Emergency Navigation

  • Find your local latitude by measuring the angular elevation of Polaris (in the northern hemisphere) or the two stars of the Crux constellation (in the southern hemisphere).
  • Measure any latitude to keep a course at a given latitude.
  • Perform trilateration.
  • Measure the angular distance between two stars.

For soldiers and other military professionals out in the field who want to use the Wndsn Products, it may be useful to alert your chief regarding what a Telemeter or Quadrant does and why it is useful. Our overarching goal at Wndsn XPD is to provide mission-critical support in an array of tactical conditions.
