The Beta Wave Emitter is a compact, handheld device with a retro-futuristic design, featuring a cylindrical body made of brushed metal with visible wear and tear, indicative of its post-apocalyptic origin. It has a series of glowing blue indicator lights along its side, suggesting active energy emission, and a small, circular screen displaying waveform patterns. The top houses an emitter dish with a slightly cracked glass cover, emitting a faint blue glow, and the device is adorned with industrial-style bolts and seams, emphasizing its rugged construction.
