The best way of dealing with any type of crime is prevention.  A crime can be prevented right up until the last minute. Even if an attacker is approaching you, it is still not too late to prevent an assault or robbery from occurring. Personal security alarms can be a good way to dissuade anyone who is considering committing a crime against you. An attacker is always on the lookout for easy prey, and the sound of a loud pitched alarm is often enough to give them reason to leave you well alone.

Personal security alarms range in sophistication from a simple whistle to more technologically advanced merchandise. A whistle kept around your neck will work well enough in most cases, but for more peace of mind you might want to consider something a bit more upscale. It is possible to purchase a personal attack alarm that can fit into the palm of your hands and lets out a 120 decibel piercing siren that nobody can tolerate for more than a couple of seconds. This then will serve two functions; it will draw help your way and it will also make most would-be attackers flee the scene straight away in order to escape the ear-shattering noise.

Personal security alarms can be as simple as your own mobile phone. You need to be careful to avoid pressing this by accident, but putting 911 or your local emergency number on your speed-dial facility can have help quickly on its way to you. This will work great in some situations, but if it is an attacker about to move on you then emergency help will likely come too late; combined with a whistle or an electronic alarm then this would be an ideal combination.

No matter what device you decide to use it is vital that you become familiar with how to use it, and keep it in a place which is always close at hand when you need it.  An attack situation is extremely stressful, and your mind will not have time to be thinking about where you hid your attack-alarm or whistle. A good idea would be to have regular practice runs in the same way that you would with fire drills. That way if you ever need to use it for real then you will be prepared.

Personal security alarms are a good idea for those wanting to dissuade any attacker or thief.  They are only useful if you are ready to use whatever device you choose; so keep them close and make sure you know how to use them.
