Personal Attack Alarms
Personal attack alarms can help people feel more secure.
One that seems to have covered all the angles is the Trident Personal Attack Deterrent, which comes with three functions:
1. A 138 Decibel Sound Output – continues to operate even if dropped to the ground
2. An Ultraviolet Tracer – can only be viewed under an ultraviolet light as used by the Police
3. A Repulsive Odour – discourages the attacker and leaves a distinguishable smell on the attacker’s skin and clothing
A real deterrent
