ZeroTech Optics USA and Infinite Outdoors have launched a joint effort. Buyers of ZeroTech gear now get a free month-long trial of Infinite Outdoors access through its digital tools, and Infinite Outdoors participants obtain a quarter off ZeroTech merchandise ordered on the web. The Nashville firm offers hunting scopes, reflex sights, field glasses, and observation optics as Infinite Outdoors connects people to private land for hunting and angling.
