OVERVIEW
The RSJ-100A is a suspending minnow that pairs long casting distance with an ultra-realistic, deadly action that holds up under heavy fishing pressure. A moving centre-of-gravity tungsten weight gives it overwhelming casting distance.
It is a collaboration model between ADUSTA and China's FREE LURE: a sharp lure design born in China's tough fishing environments, combined with ADUSTA's lure-design and colouring know-how to create an easier-to-use plug.

“A small spark makes a great fire.”
Even the smallest things hold the power to create a massive impact.
The strength and hidden potential packed into this micro-crankbait.
