A slottable sensor unit can be found on the speciality vendor on drommund kaas. It really is pointless though, i was determined to use SCORPIO but it was a complete waste of time. Mine has All purple 51 armourings (belsavis dailies) and 50 purple mods and enhancements, earpiece, implants etc... and is still far below other companion tanks. Really pointless....says some cool stuff though!
