Here is the prototype Model TRG1 Targeting Goggle designed by Caelyn of the Teks, and manufactured by the Tek's new manufacturing guild.
This design is made using a proprietary new metal treatment process, which has a side effect of a distinctive purple patina.
They assist in tracking long distance targets such as airships, naval vessels or even fast moving wildlife.
These are made from plastic welding goggles, the lens cap attachments are also made of plastic, the cross hair is brass clock gear that just happened to fit perfectly inside the attachments. Metallic finishes achieved using AMACO Rub-n-Buff.
