A trolling diver has a release arm which is hingedly connected to a plate. Mounted to the plate is a catch assembly. The catch assembly secures the release arm in a loose manner, between a first panel and a second panel, until triggered by a fish bite. A thru-hole of the release arm receives a first and second retaining member. The retaining members are loosely positioned into the thru-hole, allowing for the plate to realistically flop about within the catch assembly. The release arm is released from the catch assembly when a lure is triggered by a fish strike, resulting in the release arm rotating away from the catch assembly. The outboard lure attachment hole increases leverage and decreases the requisite force to trigger the release arm. Once released, the entire diver pulls thru the water with very little friction, allowing for easy retrieval of a hooked fish.
