Quadrant Telemeter Official Manual

The Wndsn Quadrant Telemeter manual provides the description and describes the use of the Telemeter, Horary, and Sine Quadrant.

Now available, the 4th edition enables the user to hold a complete understanding of how to independently calculate crucial measurements that we often ignore, take for granted, or assume are impossible outside of highly involved, highly technical contexts.

The 4th edition, once more revised and expanded, furthers the user's ability to directly apply a range of fundamental scientific concepts such as calculating distance, height, time and date without the use of electronic, digital, or networked equipment. The goal of Wndsn instruments is to increase self-sufficiency and broaden the understanding of the concepts underlying how we navigate through space, time, through a variety of urban, challenging, or wild contexts. At the core the 4th edition is a love letter to trigonometry and all of the ways that its principles apply throughout our daily lives; ways that usually allude us as we maneuver through the demands of modern life.

Information regarding ancient navigational methods are ever relevant and this newest edition of the manual expands the modern user’s understanding of astronomical systems, providing concise and tangible instruction. The 4th edition reiterates the constituent concepts of calculating distance with clearer fundamental and clarifying graphics; all previous material is included and updated, including the Time & Space addendum that previously introduced setup, history, as well as the functions and tutorials regarding understanding the ancient fundamentals behind the measurement of time and date.

The 4th edition further includes,

  • 30 new topics
  • 398 pages, increase of 158 from the 3rd edition
  • 129 graphics, increase of 57 from the 3rd edition
  • 22 tables, increase of 5 from the 3rd edition
  • 40 equations, increase of 16 from the 3rd edition
  • 77 entries in the bibliography, increase of 39 from the 3rd edition

An abridged version of the 4th edition is available as a free download with every Telemeter. At 212 pages, it is pared down to just setup instructions and tutorials. A German edition is also available.

Efficient learning and accessible information is the overarching goal for the 4th edition. The examples and tutorials utilize only the most salient formulas and only require the Quadrant for measurements and computations (plus pen and paper for note-taking). The expanded reference section is a standalone resource for emergency or austere situations. The novice, the seasoned practitioner, and the educator looking to demonstrate mathematical concepts in tangible ways are equally addressed.

Quadrant Telemeter Manual Cover

The official Wndsn Quadrant Telemeter manual. The cover design pays homage to medieval mathematical and astronomical books; the styling of the title as a "Grimoire" is a play on textbooks of magic with instructions on how to make spells, talismans, and the like, "Grimoire Quadrantis Telemetrum" -- Textbook of the magic of Quadrants and Telemeters. Finally; the author's name at the top; "Filiusventi" is a hint at the practice of Renaissance scientists to latinize their names; venti is wind, and filius the son.
