I may be new to the forum but not to train horns. I started out with the 200psi conductor set with the 3 gallon tank. I have upgraded since to K5 with a 15 gallon tank. There have been times I’ve honked the horns with the conductors set and people haven’t jumped but everytime i honk the K5’s, everyone jumps. Im glad to see a forum that i can post my scares on.
