Introducing the Wndsn High-Viz Quadrant Telemeter

“I don’t paint things. I only paint the difference between things.” –Henri Matisse

Wndsn Messtechnik is introducing the latest iteration of one of the most popular Wndsn Telemeter products. After more than a thousand units sold, the new white Wndsn Quadrant Telemeter is released in the beginning of 2020 in a high-contrast, high-visibility version with a number of new features.

The Wndsn Quadrant Telemeter is a measurement and calculation instrument for indoor and outdoor use, its users require attributes such as ruggedness, durability, and integrity of the various scales. For black and transparent instruments, Wndsn uses cast Acrylic that works reliably under these conditions and is deep-engraved.

To increase legibility without losing durability in the process, after various tests examining legibility, resilience, and resistance of different surfaces, a new material has been chosen: A sandwich acrylic consisting of a black core with matte white outer surfaces that are cut through by engraving, thereby exposing the black material underneath for high contrast and scales that cannot wear off (a requirement that prohibits simply printing the scales).

Other new and updated features on the Wndsn High-Viz Quadrant Telemeter are:

1. A 100 MIL mark on the angular size scale, it’s a special value for various calculations, one of which being the point where an object of unknown size has a height of 0.1x the known distance, or vice versa.

2. Another scale mark, just as easy to miss; this one is also to be found on the angular size scale and is located at 7.5°. Wndsn’s naked-eye astronomy users have asked for this one, 7.5° equals 30 minutes of earth rotation and the mark can be used against a fixed star to measure minutes passed in the sky.

3. The slope/tan scale on the quadrant side received a makeover and got redesigned according to the updated Wndsn style guide for logarithmic scales. The result is a more refined scale with higher precision and better readability.

Wndsn Telemeters are wallet-size distance and altitude nomographs developed in the Wndsn applied science lab. They combine a thousand years of civil engineering, surveying, navigation, and astronomy in durable, low-tech, high utility instruments that can be brought anywhere, are self-containing, and independent of external, modern technologies.

The Wndsn Quadrant Telemeter is a naked-eye observation instrument for measuring angles via various inputs and sighting methods. In addition, the Quadrant Telemeter is a graphical, analog computer providing functions to directly process or convert the acquired values.

Scales on the Wndsn Quadrant Telemeter:

+ angular size and distance
+ height or depth of object
+ altitude or elevation
+ computation of sine, cosine, and tangent from a given angle and back
+ degree and slope quadrant
+ shadow square
+ inclinometer

The various engraved scales enable the user to copy dimensions from the real world onto a small ruler in their hand, and read the matching distances directly from the instrument, thereby computing arbitrary navigational distances and other essential information about the world around us, as long as a triangle is formed between user, scales, and object of interest.

Under certain conditions or in cases where laser rangefinders tend to fail or result in errors, Wndsn Telemeters prevail and can be used as primary or “second opinion” tools, to cross-check values obtained with different means, or in austere situations when other methods fail or are unavailable.

The credit-card sized instrument is handmade in Germany and manufactured in the spirit of astronomical instruments of the Renaissance, built by the likes of Tycho Brahe, Johannes Kepler, Galileo Galilei, and Gemma Frisius. The scales are laser-engraved and precision-cut into 3 mm black, acrylic with white, matte surfaces. The device carries the Wndsn maker’s marks; scientific instructions are engraved and supplemented by a printed how-to in both English and German. A 240-page printed manual is included as a PDF and is also available separately at Wndsn or via bookstores.

2019 Update of the Wndsn Grouping-to-MOA Converter

From shot groupings to MOA in one piece-of-string operation with the Wndsn Grouping-to-MOA Converter.

A tool for training and practice, the Wndsn Grouping-to-MOA Converter enables the user to take out the guess work of calculating shot grouping MOA, thereby eliminating mental calculation errors. The device is based on the same principle as other Wndsn instruments, a nomogram; a graphical calculator that requires two inputs (here the grouping in cm or inch and the range distance in m or yd) to compute the output, namely the grouping in MOA. It works by entering the shot grouping and the range distance and read the resulting MOA, all by aligning the provided string across the three scales.

The Grouping-to-MOA converter provides different range scales on the front and on the back of the device respectively; the front is suited from 0 to 100 yards and the back set of scales is suited for 100 to 600 yards (or meters, respectively).

The updated, redesigned version of our Grouping-to-MOA Converter model for 2019 features standardized scales, and higher precision in input and output. It comes with a printed manual with instructions in German & English.

Ongoing research and development of scale layouts allowed us to increase the precision by a factor of 10 in some areas of the logarithmic scale. In addition, the new version of the tool is laser-engraved in acrylic, and hence more robust than the former, printed model. Like all other Wndsn instruments, the Grouping-to-MOA converter is Made in Germany.

Introducing the 2019 Redesign of the Wndsn MIL/MOA Range Calculator

BERLIN, 2019-04-04 –

“Range Finding When the Lights Go Out: Creating Information Superiority in Volatile Situations.”

Wndsn XPD, maker of low-tech, high-utility tools and instruments introduces the updated version of our Mil/Moa Calculator for 2019. A scale redesign increased the precision by a factor of 10, also, this version has the capability to calculate yard distances from target sizes given in inches.

Further improvements went into materials and production; this version is laser-engraved in 1/8” acrylic, and hence more robust than the former, printed model.

The instrument is accompanied by a 28 pages digital manual, typeset as a high quality PDF.

Designed for professional and recreational use, the MIL/MOA Distance Calculator (MMC) allows the user to input the MIL or MOA from their reticle and return the distance to the target of known dimension, thereby taking out the guesswork of gauging distance, enabling accurate range estimation and eliminating mental calculation errors while under stress.

“How far is my 3.5 mil, 12 inch target again?”

The MMC scales are unitless, which means that the user can input MIL or MOA on the left side, and for the object size, if the value is in meters, input meters on the S-scale, and read the resulting distance meters on the D-scale. If the object size is in feet, feet is input and read as feet; to convert the result from feet to yards, the value is divided by 3. If the target size is in inches, the inner, left hand S-scale is used, which is graduated as 3 feet divided in 12 inches each. Inputting inches this way, the resulting value on the D-scale is in feet.

For sub-degree angular sizes (1° = 60 minutes or MOA), the MMC provides increased precision by allowing to directly input and calculate in MIL (milliradian) or MOA and thus can be used as a high distance/high precision companion to Wndsn Telemeters — it uses the same principles of calculating distance from angular size, only that with the MMC, the sighting and measurement isn’t done with the naked eye on the instrument but instead, the input values come from range finding reticles or similar devices.

Wndsn Pocket Quadrant Telemeter

We’ve showed you Wndsn’s pocket calculators before. These trigonometry based tools allow the user to calculate distance, angles, and more with the need for electronics or electricity… none… at all. Their newest tool, the Pocket Quadrant Telemeter, is likely their most ambitious tool yet.

The basic function of this tool is to determine distance based on known object size but it can do a lot more than that. In fact, it has about 50 different known uses and the math involved is flexible enough that people are still finding ways to use it. The Pocket Quadrant Telemeter comes with an acrylic card etched with graphics that contain all the baked in trig functions, a dyneema cord, a tungsten carbide plumb weight, and a sleeve.

It also includes a printed cheat sheet for using Wndsn Telemeters and a digital copy of their comprehensive guide to telemeters. These instructional items are a must if you plan on even scratching the surface of what these tools can do.

Wndsn Telemeters: Official Manual

Maybe you’ve read about Wndsn XPD’s telemeters on these pages and thought they looked cool but wondered if you would ever be able to to figure out how to use one. I suspect that is a pretty common sentiment because Wndsn just released a new manual called Wndsn Telemeters: Official Manual.

The manual includes basic instruction on using a telemeter which is actually relatively simple. It also includes instruction for a number of more advanced uses of their telemeters.

  • Extending the Scales
  • Measuring Latitude for Celestial Navigation
  • Powers of 10 and Scale Jumps
  • Measuring Angular Size
  • Measuring Size Instead of Distance
  • Resection: Triangulation, Trilateration, Triangulateration
  • Resection Error Margins
  • Small-Angle Calculations
  • Accuracy Estimations
  • Calibrating Device Resolution

Even if you don’t have a telemeter, you may want to consider a book like this. You can even use the back cover as a telemeter!
