I found this site from a thread on PBN that Josh told me about. It was in a member's sig.
Tells all about the Impulse, and the Shocker. And it also has things like a Shots per Tank Chart, and a Paintball Size Chart, and more.
Very nice site.
I'm putting this in here because it mainly contributes to SP products. But if a mod would like to duplicate this thread, or something, for the other forums like Air Systems, and Barrel's & Paint, go ahead.
Also, just to let you guys know, the SP site has finally been updated. Check it out.
