Theon NYX is a Binocular series made by Theon International(Theon Sensors).
These same devices are also known as Elbit Systems Of America's PVS-31D. They have the US mod dovetails unlike Theon NYX dovetails with stow cutoff contacts.
Theon NYX is compatible with standard MX-10160 37mm tubes. Manual gain can also be enabled if you use 3 pad MX-10160 tube, or MX-11769 if you remove the 3rd pin and solder 4x pigtail pin sockets.
Theon NYX has two alternative models.
Theon NYX FE is a lightweight version of Theon NYX. It doesnt have an adjustable diopter, similar to PVS-31A.
Theon Trident is an autogain version of Theon NYX. It doesnt have the manual gain knob, but a rotary knob power switch instead.
