Tactical Seismic Coupler, Mk 5

Technological

Drone cameras and magical scrying can do a great deal to illuminate the potential hazards present on a battlefield and to aid in the gathering of data during scientific surveys, but some situations require more grounded thinking. A tactical seismic coupler (TSC) is a spherical device resembling a grenade with six spikes protruding from it, each one connected to a three-component geophone housed inside it. You activate a TSC by making an attack as if it were a thrown weapon with a range increment of 20 feet, targeting an intersection with an AC of 5. Upon landing, the TSC sends near-surface seismic data back to a personal comm unit or datapad within 100 feet that you’re carrying, giving you the senses listed for each model while you are within the model’s listed radius of the targeted intersection. These benefits last 1 minute.
