Unlike its predecessors, Nexus has a totally new design in both the phasor and pack. The older model, black plastic phasor cases were scrapped and replaced with a new transparent case complete with members button reader on the side of the phasor (Infusion has it located on the front of the vest). Nexus is also one of the first laser tag systems to use green lasers rather than the standard red lasers used in most laser tag systems. New LCD screens in Nexus Pro replaced standard LCDs used in Infusion and Nexus FEC.
