Separate alarm myths from real-world use. Learn what a loud alarm can and cannot do, and how it compares to pepper spray for deterrence.
Quick answer
A self defense alarm can deter some attackers by drawing attention, but it is not a guaranteed physical stopper. Its effectiveness depends on the situation, the attacker's motives, and whether you can activate it in time. For direct physical defense, pepper spray is more reliable, but it also has limitations. The best approach is to understand each tool's role and choose based on your comfort and needs.
Myth: A loud alarm always scares off an attacker
A 130-decibel alarm is piercing and can startle or disorient someone. In many cases, it may cause an attacker to flee because it draws unwanted attention. However, not all attackers are deterred by noise. Someone determined or under the influence might not react as expected. The alarm is a tool for attracting notice and creating a window to escape, not a force field.
Myth: Pepper spray is always better than an alarm
Pepper spray can physically incapacitate an attacker by causing intense burning and temporary blindness. But it requires you to be close enough and to have it accessible. If you are not comfortable with close-range defense or live in an area with restrictions, an alarm may be a better fit. The Go Guarded Hand-Held with Pepper Spray combines both, giving you options depending on the situation.
Myth: You can just press a button and you're safe
An alarm only works if you can reach it and activate it in time. Fumbling with a keychain or purse can waste precious seconds. Practice pulling and triggering your alarm regularly so it becomes second nature. The same goes for pepper spray: know how to unlock and spray without hesitation. The Go Guarded Self Defense Kit includes a hand-held unit that can hold either the alarm or pepper spray, so you can train with the configuration you carry.
Verdicts on common alarm claims
- Claim: A loud alarm guarantees an attacker will run away.: Alarms can deter by attracting attention, but response varies. Some attackers may be undeterred by noise alone. Verdict: Partly true. Use as a deterrent, not a guarantee.
- Claim: Pepper spray is always more effective than an alarm.: Pepper spray can physically stop an attacker, but requires proximity and correct use. Alarms work from a distance and are less likely to be restricted. Verdict: False. Each has strengths; choose based on your situation.
- Claim: You don't need to practice using an alarm.: Under stress, fine motor skills decline. Regular practice ensures you can activate the alarm quickly and confidently. Verdict: False. Practice regularly for reliable use.
