Shown above is the Silver Pulser AKA ZBB5. This is a dual use unit: Colloidal Silver Maker; Blood Electrifier.
The photo has been modified for discussion. At the center bottom is the main electronics enclosure (pocekt sized) of the ZBB5, a small white gadget circled in black. The top side of the unit has a few LEDs and a dial to operate and monitor operation. On the front end of the unit (not visible from the angle shown) there are two jack receptacles, one DIN, one for attaching the included AC/DC power supply. The DIN receptacle is where you optionally plug in either the Colloidal Silver attachment, or, the Blood Electrifer attachment. When being used in Blood Electrifier mode, the unit only runs from battery power. When used in Colloidal Silver mode, the unit can optional run from AC power. In the above photo, the Electrifier attachment is on the left, circled (mostly) in black. One end of the attachment plugs into the DIN receptacle, the other end are the two pinky-sized probes that get strapped to radial pulse points. Look closley and the bag of little cotton booties can be seen - these are used to cover the probes before attaching to wrist, ideall, they should be moist with water for best contact. Near the center of the photo there is a semblance of a double arrow intended to point out the Ionic Silver attachment (upper part of arrow) and the package of silver wires shipped with the unit. The package shown is the relatively long, narrow white looking thingy that contains at least 2 thin .9999 silver wires about a foot long each. Also shown is the included accessories: small dropper bottle, perhaps for storing a small mobile supply of Colloidal Silver; some eslastic straps; attractive carry case; a small hunk of green scrubby for keeping the wires & Electrifer probes clean... works pretty well for the wires, but the probes are really difficult to keep clean.
The same company makes a separate product called the Mag Pulser that includes a similarly looking white electronics enclosure that has LEDs and a dial/button. A Mag Pulser attachment wand is included that is basically a small white plastic paddle wand looking thingie about a foot long. This wand is several inches of a handle at one end of which the wand ends in a round circular pad shape, this is where the mag pulses eminate from. The other end of the wand has the cable that connects into the electronics enclosure. In the case of the ZBB5, the attachments are plug-interchangable (you can plug them in, you can unhook them), but on the Mag Pulser, I think the attachment is fixed (hard wired), you cant unplug and plug it, it's always plugged.
All told, these 2 products give you a three-pronged Beck Protocol approach.
