Wndsn High-Viz Quadrant Telemeter (wqTM) 75x7x500q90i30 White Acrylic

Our bestselling Quadrant Telemeter; a measurement, calculation, and exploration instrument with thousands of units in use by professionals such as emergency, security, and law enforcement personnel, also teachers and instructors, as well as private enthusiasts, urban explorers and adventurers.

As seen on Soldier Systems Daily and on Spartanat.

The latest update to the standard qTM model (v. 23n). Changes are: minimized shadow square and addition of a dot grid pattern.

A multi tool for makeshift navigation, recon, and rangefinding, the double-sided Wndsn Quadrant Telemeter enables you to do more than merely guessing distances. Find an object of known size, or distance, or angle and use the frontside Telemeter to measure and calculate distance with the enhanced vision piano scale and utilize the baked-in trigonometry to find the desired value by aligning the provided string across the various scales.

The backside features a Surveying Quadrant to measure degree and slope, a minimized shadow square, as well as sine and cosine arcs and an inclinometer scale. By using our string as a plumb line, we offer three ways of sighting with the quadrant, plus we let you perform various trigonometric operations with the shadow square and sexagesimal scale with a useful enclosed dot grid, increasing the usefulness of the instrument with the list of applications topping 75 currently. The Quadrant Telemeter lets you measure angular size and compute distance, height or depth of object, altitude, or elevation, it allows computation of sine, cosine, and tangent for a given angle -- it can even be used as a star compass.

The best tool is the one you have with you, on you. Wndsn Telemeters are wallet-size distance and altitude nomographs developed in our applied science lab: Wndsn Telemeters combine a thousand years of civil engineering, surveying, navigation, and astronomy in one durable, low tech, high utility instrument that can be brought anywhere, is self-containing, and independent of external, modern technologies. Wndsn Telemeters are naked-eye tools that offer various means of measuring angular size, as well as graphical computers providing functions to process or convert the measured values. Their purpose is to help you navigate using known landmarks or astronomical features, to get a "second opinion" to cross-check values obtained with different means, or in emergency situations when other methods fail or are unavailable.
