Shortboom
From ALttP Speedrunning Wiki
Shortboom refers to a phenomenon where the boomerang travels a shorter distance than expected. This happens when the boomerang hits what is known as a search beam: invisible sprites rapidly fired out in an arcing pattern to detect Link. These search beams are used by guards and beamos, and are most commonly hit when the boomerang is thrown directly towards a guard. Despite its name, this glitch also affects all other airborne ancillae.
