The Sabre Red Starter Pack is a great option for those that would like to carry pepper spray. The kit comes with both a live (black) and training (blue) pepper spray canister. The spray is a gel, which limits blow back and give stream like accuracy. The trainer can give the user a good idea of what to expect should they ever use the live spray.
Learning about the spray is important and Sabre recognizes this to be true. With the trainer, you can see the effective range of the spray, the dispersal pattern, and you can practice with it to be more accurate. In addition, the trainer will allow you to see how wind affects the pattern and how much blow back you can expect to contact.
All said, this kit is affordable for around $18-$20 and will give you more practice with one of your defensive tools.
