While all Photons come standard with a built-in IR illuminator, dedicated hunters will welcome the invisible 940nm IR illuminator, standard on non-‘S’ models; this IR light does not produce a red glow when viewed directly. A side weaver rail on the Photon allows shooters to attach additional accessories or IR lights to increase performance and application uses. Continuing to keep the user in mind, Photon RTs also boast 6 reticle options, one-shot zeroing, IP55 water-resistant protection and a recoil rating up to .375. All Photon RT models come standard with carrying case, USB cable, spare battery container, battery container pouch, lens cloth and user manual. Photon RTs are revolutionizing the affordable night vision optics game.
