The inline reverse action, spring-loaded fishing tackle device of the invention is a simple but effective device used inline with any fishing rod and lure that aids in the capture of fish. The device is comprised of a cylindrical shaped casing divided into two interior chambers which house a unique reverse action, spring mechanism that automatically maintains a constant counter force on the fishing line against the tugs and pulls caused by the erratic movements of a caught fish, whereby not only helping to hook the fish but also preventing any slack in the fishing line that could cause the loss of said fish.
