DIY ice fishing rig fires rockets to signal catch
Going fishing in ice means having to sit out in the cold for hours. One DIYer solved that problem by rigging the system to launch a rocket every time a fish pulls at the hook. This guy can now sit comfortably, basking in the knowledge that the rocket will be fired when a fish is caught and that’s the time he needs to go out into the cold.
