S90 Standard Coil
S90 Standard Coil

The S90 Standard Coil produces a broad magnetic field that takes place directly under the windings, forming a ‚Äėdonut shaped‚Äô field. Compared to standard 70mm double coils, this magnetic field is wider and can be slightly deeper, ideal for stimulating large peripheral nerves. The coil can be used on both sides for current reversal and is compatible with all Magstim research stimulators.
