planet eclipse shocker
"The pneuVentures Shocker was sold up until 1997 when SP redesigned it and started producing it themselves. This redesigned marker, which became known as the Shocker Sport, was released in 1998. It included a number of major revisions to the original design, including a more lightweight profile, improved electronics and grounding, a faster cycling set of internals, and better solenoids. The Shocker Sport was sold from 1998 to 2002, and the design of its external look changed a few times over the years. A few companies even released their own customized versions, mainly the Planet Eclipse Shocker (which was manufacturered by SP for the company Planet Eclipse, which at the time didn't make any markers of their own). Another customized Shocker was the SL Shocker from HyperSportWorks."
