The Duo Tetra Works Bivi SMA0531 is a compact vibration bait built for precision and versatility in saltwater and light game fishing. At 40 mm and 3.8 g, it casts exceptionally well thanks to its high-density body and falls quickly, making it ideal for covering wide areas. A built-in 3 mm tungsten ball creates a unique rattling effect not found in solid metal lures, drawing attention from predators. Perfect for fishing from breakwaters, tetrapods, or open water, the Bivi is effective on rockfish, scorpionfish, barracuda, and seabass.

Media & How-to

Rigging Tips:

Cast long and allow it to sink to the desired depth, then retrieve steadily or with small lifts for strong vibrations. Its fast fall and rattling action make it an excellent search bait.
