This is the Stainless Steel Trigger for Automatic Fisherman this is our trigger system for the Automatic fisherman unit. I am selling them separately knowing that some people will make there own units. There is a lot of personal satisfaction when you make a device yourself and catch fish with it. So I would like to share my experience with you and offer you our triggering system we have. When you buy the Automatic fisherman unit they come with a lifetime warranty, so if yours broke please contact me for a replacement.
