[Source] Model TT4 Holorecording Macrobinoculars were a series of holorecording macrobinoculars manufactured by Neuro-Saav Corporation. Like most macrobinoculars, the TT4's had an internal readout system that provided information on distance and elevation. The TT4's were also capable of recording and playing back what the user was viewing, making the earlier models rather expensive. Each recon squad in the Praesitlyn Defense Force was given only one pair.
