Wndsn Custom Astronomical Quadrant Telemeter (LHqTM)

This device, formerly known as the Wndsn Custom Latitude Horary Quadrant Telemeter (LHqTM) 8x6x500q90i35 High-Viz, is now renamed. It's a custom astronomical quadrant with equal hours and a calendarium, tailored to specific latitudes. Choose your closest latitude and opt to include stars (up to four). Allow approximately 14-20 working days for delivery.A versatile tool for education, makeshift navigation, and rangefinding, this double-sided telemeter lets you measure angular size, compute distances, heights, depths, altitudes, or elevations. It also enables sine, cosine, and tangent calculations using its built-in trigonometry.The backside features ancient astrolabe-derived functions: a degree and slope quadrant, shadow square, sine and cosine arcs, and an inclinometer scale with horary lines. It allows sun's altitude measurement, time-taking, and daylight hour visualization. Multiple sighting methods and trigonometric operations are possible, with over 75 applications.Using this telemeter, you can determine latitude (at night with Polaris), calculate declination, and measure sun altitude, deriving at least 18 data points directly on the device.Crafted in Germany, this durable, low-tech, high-utility instrument combines a thousand years of civil engineering, surveying, navigation, and astronomy. It's a naked-eye tool offering various angular size measurement methods and graphical computers for value processing or conversion.Includes a Dyneema string, stainless steel plumb line weight, a 32-page pocketbook (English and German), and a 240-page digital manual (English, German on request). Slight finish variations may occur due to manual production.Specifications: 3.4" x 3.4" (8.5 x 8.5 cm), matte white surfaces, black core, 1/8" (3.2 mm) acrylic stock, laser engraved.
