Product Description

These PPD's are an inexpensive device designed to assure our defense against those predators that sometimes visit us while spearfishing.

Your Personal Protection Device is made to fit all the shells of the above description. It has NO FIRING PIN, and as such, cannot be classified as a weapon. It must be placed over the pointed tip of a 5/16" spear shaft and shot into or onto an object underwater. It is NOT meant to be fired above water and should be fired with enough force to counteract the firing of the shell.
Below is a picture of how your P.P.D. should be placed on your spear.

You can use our PPD’s forever, IF you remove the shell and rinse after being in salt water. Aluminum and brass grow together if you don't. Best bet is to load the cartridge, replace rubber bushing, then seal them in a zip lock. I use a food sealer and make the bag small as possible. This way, you can dive with it many times without having to unload and rinse.
When ready to use, push your spear point into the bushing and push firmly down till it stops on the shell. This keeps a deflecting blow from causing a misfire. (no fire at all). To keep from losing your PPD after firing, note the groove at the upper end. Tie a thin nylon line tightly into the groove, Make a loop in the other end that will loop below your flopper (barb). If you insist on trying your PPD above water, stop at a gun shop and buy a dozen blanks.
Use these to check it out, and also to show your friends how easy it fires when placed on your shaft and just popping it down on a piece of wood.
