A tip-up fishing device includes a cross frame having a horizontal section that spans a hole cut in the ice and a vertical section that supports a spool of fishing line down in the hole. A trip device operates to release a spring elastic flag pole when a fish strikes the line. The flag pole springs upright and is caused to depress a push-button transmitter switch mounted on the frame. The switch sends a signal to a remote receiver which generates an alarm signal to alert the fisherman.
