With figure of eight coil winding footprint of only 41mm x 84mm, the Verta Coil is one of the smallest figure of eight coils available from Jaltron. The increased stimulation accuracy limits this coil's depth of penetration making it only suitable for small brain sizes. This coil is not cooled and due to its small size warms up faster than larger coils. It is the same as the Binocular Coil with the exception of the cable which comes out vertically from the top. Two windings are side by side each having an inner diameter 18mm, outer diameter of 41mm, and a winding height 12mm, approximately.
