An ice fishing device enclosed in a housing and configured for indicating that a fish has taken the bait is disclosed. The device provides a curved rod having a portion external to the housing and a portion internal to the housing. The portion inside the housing includes a curved end adapted for resting on a handle tip of the fishing spool. The curved end will release from the handle tip when a fish tugs on the fishing line, thereby moving the spool and the handle tip away from the curved end. Once the curved end is released, the curved rod containing a flag repositions to an upright position, alerting the fisherman that the fish is ready to be pulled out of the ice.
