Thanks for that photo, and wow, I didn't realize the damage it could do. Maybe I'm a sissy but I've been reluctant to stick my finger near the transducer. People say it hurts, but what is pain anyway? Is it real? It's just electrical impulses. That can't be real horrible. Besides, pain is such a rush. It let's you know you're alive. I was certainly alive when I slid the throttle cable under my thumbnail. OK, so back to work on the weed guard for my fogger.
