In the past few years, we have covered plenty of pepper sprays here. The Guard Dog AccuFire takes it to the next level with a laser sight. It has a compact design and range of 16 feet. The device fits on your keychain and lets you spray with more accuracy. It also comes with a UV dye to identify assailants.
This self defense tool uses 18% Oleoresin Capsicum (red pepper) spray.
