The Otter is a prop bait with a prop that rotates even at a dead slow speed and a body that eliminates unintended movements, achieving the ultimate in "weakness specialized for luring fish." Its removable insert weight allows it to be used at any depth. Without the weight attached, the buoyancy is deliberately set for slow sinking just below the surface, maintaining a stable swimming motion even in adverse conditions like choppy water and wind. It attracts bass that are hesitant to feed on the surface and reduces the chance of the lure being thrown off by the force of the feeding. Adding a weight also allows for adjustable sinking speeds to accommodate a wide range of depths, from mid-depth to bottom. Furthermore, the wire guard attached to the weight detects and avoids obstacles and the bottom, enabling it to tackle tight cover, a weakness of previous prop baits. Rather than relying solely on the call-up effect near the surface, this aggressive prop bait boldly attacks productive zones.
