This is one of Wndsn’s first acrylic tools and it has a unique feature that takes advantage of this optically clear material. There is a slot in the Telemeter Pendant that is sized to accept miniature glow sticks. The glow stick illuminates the markings on the Telemeter Pendant, allowing it to be used in low light.
