"It belongs in a museum!" - Indiana Jones

Own and display a genuine piece of technological history.

These 'water-cooled spark gaps' were hand-made and come signed by their original inventor (me), are numbered in order of production and are the very first and only WCSG's available for public sale. This special 'Series 1' edition is a limited hand-crafted build of just 20 units per model. They come with accessories such as capacitor discharge sticks, electrode form tools and a super-cool 'high voltage' decal.

Towards the future!
