The TSS-2 'Convergence' is ShieldTech's dual-baton system — a matched pair of 45-centimeter short batons designed to be used simultaneously by a trained two-handed operator. Each baton is functional as a standalone shock device, but the system's distinguishing feature is its Synchronized Discharge Architecture (SDA): when both batons contact a target within a 500-millisecond window, the system detects the closed circuit and delivers a coordinated dual-discharge that routes current between the two contact points through the target's body, rather than to ground. This dramatically increases current density through the target's torso and creates a more comprehensive neuromuscular disruption than either baton could achieve independently.

ShieldTech developed the Convergence for close-quarters combat specialists and executive protection operatives who operate in environments where long batons are impractical — vehicle interiors, narrow corridors, elevator confrontations, close-press crowd situations. The short form factor allows both batons to be carried in a dual-hip holster rig or concealed in a jacket's inner pockets. The synchronized discharge requires deliberate two-point contact, which means casual or accidental discharge is less likely than with standard single-baton systems, a safety feature ShieldTech has emphasized in its regulatory filings.

The training requirement for effective dual-baton use is nontrivial — operating two weapons simultaneously while maintaining positional awareness is a skill that requires practice to develop — and ShieldTech offers a certified training program through its authorized dealer network. The Convergence comes with a 'solo mode' that disables SDA and allows each baton to function independently as a standard 130,000-volt device, which most purchasers use until they complete the dual-operator training.
