A belt-worn personal electromagnetic barrier that generates a brief repulsive field on activation, physically pushing back anyone within a one-meter radius with approximately 200 newtons of force — equivalent to a hard shove from a large adult. The BB-5 does not create a persistent shield; instead, it fires a single omnidirectional electromagnetic pulse that interacts with the iron content in blood and the metallic components of clothing, cyberware, and weapons to create a momentary repulsive wave.

Aegis developed the BB-5 from military crowd-control technology, scaling it down to a consumer wearable that clips onto a standard belt or waistband. The device is roughly the size of a smartphone and weighs 240 grams, most of which is the high-density capacitor that stores the charge for the repulsive pulse. A full charge provides three activations, with a fifteen-second recharge delay between pulses. The activation button is positioned for thumb access on the wearer's hip.

The BB-5 is Aegis's flagship consumer product and represents the most affordable personal barrier technology available. At Φ850, it is beyond Tier 1 budgets but accessible to Tier 2-3 residents who prioritize personal safety investments. The device has limitations — the repulsive force decreases with distance, is less effective against individuals with minimal metallic content (unaugmented, no metal jewelry or closures), and the three-pulse capacity means it is a short-duration deterrent rather than sustained protection.
