Bottomup Doubler

Bottomup’s Doubler is a buzzbait designed to combine the dynamic, wave-like action of its skirt with the high-pitched squeaking sound generated by its propeller. The new W Wave Skirt (PAT.P) mechanism uses optimal lengths and amounts of skirt material tied at two points, while gaps at the front and rear regulate its volume and water resistance. This produces a rolling action reminiscent of a fleeing baitfish. The asymmetrical original propeller generates powerful vibration and turbulence through its eccentric rotation, and features an anodized surface treatment. The propeller and large-diameter rivet make point contact, a design that helps develop a high-pitched squeaking sound.

The wire has a 1.2 mm diameter, combining strength with cushioning properties. Its curved lower arm positions the propeller at a slight angle against the water’s surface, transmitting vibration to the skirt. The cup-shaped head provides lift, while its low center of gravity ensures stability. The weight is set at 12.5 g (7/16 oz.). It is designed to be retrieved across the surface while generating vibration and turbulence immediately after entering the water, and is equipped with a BKK hook featuring a slightly longer shank, high strength, and enhanced penetration from its fluorocarbon coating.
