DOUBLE-TAP TECHNOLOGY
Our tools are the only tools on the market that use this technology. It cost us a great deal to incorporate it but
we maintain our position on providing a tool that far exceeds all others while still being competitively priced.
Double-Tap technology is Patent Pending
The Double-Tap system uses a proprietary "Floating Mass" technology inside designated
hammer heads and our Heavy/Light Rams. This technology can better be explained by
Newton's Laws of Motion and Galileo's Concept of Inertia listed below. But here's a short
version.

Explanation:
In an impact (Such as a hammer blow or strike from a ram) the energy is transfered from the
moving object (Tool) to the stationary object (Target) in one motion. The goal for the
breacher is to use as much of that energy as possible in the first and if necessary
subsequent blows. Double-Tap technology helps you to do this by reducing or in most
cases eliminating the vibration that is created when the tool strikes the target. That energy is
then put to more efficient use and transfered into the target and not back into the tool. With
most collapsible breaching tools the rear of the handle can experience extensive vibration
when used against most targets. Our tools were designed to overcome this problem. No
other tool on the market does this.
The initial idea was to produce a tool with less vibration in the handle by using existing
"Dead Blow Hammer" technology. After detailed analysis and design changes, the final
product proved to be better than expected with the complete absence of handle vibration
and additional energy transfer into the target. The end result was a tool that uses all
available energy to defeat the target as quickly as possible allowing rapid access into the
structure.

Newton's First Law of Motion:
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
This we recognize this as essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia".

Newton's Second Law of Motion:
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are
vectors. In this law the direction of the force vector is the same as the direction of the acceleration vector.
This is the most powerful of Newton's three Laws, because it allows quantitative calculations of dynamics: how do velocities change
when forces are applied. According to Newton an object with a certain velocity maintains that velocity unless a force acts on it to
cause an acceleration.

Newton's Third Law of Motion:
lll. For every action there is an equal and opposite reaction.

Galileo and the Concept of Inertia:
Perhaps Galileo's greatest contribution to physics was his formulation of the concept of inertia: an object in a state of motion
possesses an ``inertia'' that causes it to remain in that state of motion unless an external force acts on it.
Most objects in a state of motion do NOT remain in that state of motion. For example, a block of wood pushed at constant speed
across a table quickly comes to rest when we stop pushing. Thus, Aristotle held that objects at rest remained at rest unless a force
acted on them, but that objects in motion did not remain in motion unless a force acted constantly on them. Galileo, by virtue of a
series of experiments realized that the analysis of Aristotle was incorrect because it failed to account properly for a hidden force: the
frictional force between the surface and the object.
