Double D-shaped 70mm coil is similar to a figure of eight coil except for the flat section in the middle. In addition the windings have a 150° angle with respect to each other. The shape and angle combination increases the depth of penetration and that of the area of stimulation. This stimulating coil can be supplied with 1" ball adapter for mounting to Magstim Co. coil stand, or to Ram Mount system. Manfrotto adapter is also available.
