What is the Double Coil PMD70?

The Double Coil PMD70 is MAG & More’s standard figure-8 stimulation coil, designed for focal cortical stimulation in clinical and research TMS applications. With a winding diameter of 2×70 mm and a peak field strength of 2.0 T, it delivers precise, well-defined stimulation to superficial cortical areas — making it the go-to coil for motor threshold determination, motor cortex mapping, and standard rTMS and TBS protocols.

The PMD70 is compatible with all MAG & More stimulator systems and comes with integrated navigation points for seamless use with the PowerMAG View! 3D neuronavigation system.

Key Features

• Figure-8 Focal Geometry: The double-coil figure-8 design focuses the induced magnetic field at the coil intersection, enabling precise targeting of discrete cortical regions with minimal spread to surrounding tissue.
• 2×70 mm Winding Diameter: The 70 mm per wing geometry provides optimal focality for standard cortical applications including motor cortex, dorsolateral prefrontal cortex, and other accessible targets.
• 2.0 T Peak Field Strength: Delivers the field intensity required for reliable cortical activation at standard stimulation intensities.
• 160 μs Pulse Length: The efficient, stable 160 μs pulse length minimizes energy deposition while maximizing neural activation effectiveness.
• 800 Pulses per Session: Rated for 800 pulses at 1 Hz, 75% intensity, from a 20°C starting temperature, suitable for standard single-session rTMS protocols.
• Lightweight Design: At 1.3 kg, the PMD70 is comfortable to hold and position throughout extended stimulation sessions.
• Integrated Navigation Points: Built-in navigation markers for direct compatibility with the PowerMAG View! 3D neuronavigation system.
• Universal Compatibility: Works with all MAG & More stimulator systems.
