Recently I gave a chem spray demo at a self defense class. I had been using MACE triple action sprays for demos simply because I had some around that were nearing the expiration date and I wanted to make use of them. At the last demo I used a SABRE brand triple action because that was the oldest one I had. As we discussed not too long ago the SABRE brand uses military CS tear gas instead of the CN that MACE uses.
The night I used it was pretty calm with a very light breeze. I sprayed a little cloud that would waft over so the class could get a whiff of it and feel some effect. I walked into the cloud and took a breath and WOW did it hurt. I was expecting the CN's effect and had forgotten the effect inside the military tear gas chamber with the CS. The SABRE with CS has a much better effect than the MACE with CN, at least on me.
Do you find this to be true when testing other civilian chem sprays?
