Wndsn Quadrant Telemeter Tutorials
Making the most out of our graphical telemetry computers.
Like with many complex instruments, there are multiple ways to solve certain problems and to measure the required inputs. Combining the various functions leads to a multitude of advanced uses.
Quadrant Telemeter Official Manual
Many uses of the Quadrant Telemeter are apparent after simple instructions, but some techniques require in-depth practice and special attention to detail.
In a significant update to our beloved Telemeter, we've utilized the reverse for the first time, adding ancient quadrant elements as well as an inclinometer. This means that the list of uses and use cases of the instrument has more than doubled.
By using the Telemeter string as a plumb line, we introduce three additional ways of sighting, plus we let you perform various trigonometric operations with a shadow square and a sexagesimal scale. As usual with our tools, there are hidden secrets, and more uses than meet the eye. We look forward to exploring all this with you in the pages that follow.
The greatly expanded manual therefore will be of interest to those who want to know what this instrument and the new, ancient features are all about, or those who have just bought a Quadrant Telemeter and want to start using it, as well as the experts who want to push the boundaries of what their Telemeter can do. Various additional reference materials have also been included to give you a Rosetta stone of trigonometry and a standalone resource for emergency or austere situations.
