Best Tech for Personal Protection in 2022

by Irene Park

Despite the longer downward trend of violent crimes in the US, there was a 3% rise in 2020 over 2019. And as more and more states reopen and more people are engaging in activities outside the home, there is no better time to invest in tech to protect your safety.

While traditional personal protection gear such as mace and pepper spray have been popular in the past, they are illegal in certain states and difficult to get through airport security. Additionally, carrying a defensive device that can be used as a weapon can create more danger. Nevertheless, some people own weapons and use them either for wrong reasons or as self-defense weapons. Gun owners can be taught how to safely possess a firearm or they could also look for blog pages by searching using keywords like “300 blackout vs 5.56” so that they can be aware of the gun’s features before they use it. This might also prove to be beneficial for using weapons safely.

As important as it is to keep safe, it is equally important that such tech is portable and easily integrated into one’s life so it can actually be readily on-hand. The following is a list of tech that is both discreet and safe.
