The IPA 117 Intimidator works with a completely different method of restricting the offender's movement against the method of protection offered with the SmokeCloak system.
Whilst the SmokeCloak system produces an impenetrable cloud of dry vapour and limits the offender's vision and ability to locate the product, the IPA 117 Intimidator produces an environment that becomes simply unbearable to remain within.
This is the result of the IPA 117 Intimidator producing a completely disorientating 117db high-pitch audio level. The pitch is such that it works on the inner ear of the offender and makes for a perfectly safe, yet perceived painful and disorientating, situation.
The unit is 100% safe and legal for use.
