WNDSN XPD – Acrylic Pocket Quadrant Telemeter

Friday, July 27th, 2018

I recently ran across this pocket quadrant telemeter. It’s not something you see very often, and as some SSD readers like to keep it old school, I thought it was worth a share.

It’s a navigation, measurement and rangefinding tool. Once you inderstand it, it’s very simple to use. You locate an object of known size at the distance you need to measure and rely on trigonometry to give you the information you need. Sure, some of this can be done with a weapon optic, but that’s not always something you’ll have readily available.

Made in Germany, it comes with a Dyneema plumbline and tungsten carbide weight.
