Nils Master Big Mouth Lure in Action
In life, if you want something, you’ve got to make some noise.

The Nils Master Big Mouth is a unique hydrodynamic lure that uses the sound and motion of water flow to attract the fish you’re looking to catch.

When pursued by a predator, bait and prey fish respond with changes to their physicality and behavior. The Big Mouth lure was created to simulate these changes, mimic their natural motion, and appear exceptionally true to life.

Unlike standard lures, the Big Mouth is designed with an open channel, instead of a diving lip. Water flows through the large, open mouth of the lure, initiating the life-like movement and sounds of a panicked prey fish as it tries to swim to safety.

The Big Mouth was invented in 2002 and was the first hydrodynamic lure of its kind. Its design incorporated studies of aquarium and fishing waters, and even adapted engine technology to achieve the final product. The result is a revolutionary lure that uses hydrodynamics to guide its performance and imitate the motion of an “alarmed” fish.
