These are some pictures of a couple of the coils I use for my demonstrations.
|This coil has a 2.5" diameter secondary and produces about 12" of spark. This one is great for classrooms.|
|This coil has a 4" diameter secondary and produces about 3' of spark. This coil is suited for use in auditorium type settings.|
|This coil has a 9" diameter secondary. It is still under construction. It looks like it will be producing somewhere in the neighborhood of 7-8' of spark. Outdoor venues would be appropriate.|
|This is a special project coil that we recently built for a client|
