A deep troller weight apparatus for connecting a fishline to a weight body. This invention consists of a locking device located within the weight body for engaging or disengaging a fishline after the deep troller weight apparatus has been submerged into a body of water. By exerting a moderate force on the fishline, the weight body glides by gravitational force along the fishline towards the hook and lure for reeling in the catch. A spiral shaped guide holds the fishline at a fixed position about the deep troller weight body and prevents the locking device from releasing the fishline under relatively small forces.
