The ZAP Blast Knuckles Extreme stun gun is a compact direct contact stun gun with four spike electrodes and a rubber coated contour grip. Its hand shaped design is different from a straight flashlight style stun gun and gives your fingers a defined place to hold the unit.
This model may fit someone who wants a compact stun gun with a grip built around the hand instead of a long body or baton shape.
How Does the ZAP Blast Knuckles Extreme Fit in Your Hand?
The ZAP Blast has a soft rubber coated contour grip. Your fingers sit around the shaped body while the electrode section stays at the front of the unit.
The grip is one of the main differences between this model and a standard rectangular stun gun. A secure grip matters with any direct contact device because the unit has to stay in your hand during use.
What Are the Four Spike Electrodes?
The front of the ZAP Blast has four spike electrodes. These are the contact points used by the stun function.
This is a direct contact stun gun. It does not fire probes from a distance.
What Is the Voltage Rating on the ZAP Blast Knuckles Extreme?
This stun gun carries a manufacturer listed rating of 950,000 volts. Actual voltage output can be difficult to measure and independently verify, so this number should be understood as the manufacturer’s stated rating rather than a laboratory confirmed measurement.
P.S. Products has also published a manufacturer listed output of 4.7 milliamps for the ZAP Blast Knuckles Extreme.
How Do You Know When the ZAP Blast Is Switched On?
A red LED indicator shows when the unit is switched on. Learn where the controls are and how they work before carrying or handling the stun gun.
Keep the unit switched off when it is being stored or handled for normal purposes.
What Batteries Does the ZAP Blast Use?
The ZAP Blast uses two CR123A lithium batteries. Two batteries are included with the product.
This model is battery powered rather than rechargeable. Battery condition can affect the performance of any electronic stun device, so check the batteries as part of normal care.
