Steve88, I've bought that magnetic pulser...it is very weak....auto-pulser....all it is is a flashtube you buy at Radioshack-hooked to a coil...nothing is modified in the board, the guy just soldered the coil wires to the bulb in the flashtube....if you buy Magnetic pulser get one that uses either a Camera Flash, or build one using AC power like Chris Gupta's Plans...it's powerful...

personally I would buy the Coil off ebay $20, and then build Chris Gupta's AC powered Magnetic pulser, you can make it as powerful as you want.
