DUO’s REALIS SPINBAIT HEARTBEE is a spinbait lure that retains a baitfish-inspired body profile while adding a new level of attraction to the I-shaped category through its internal mechanism. The 75SS features a water-through design that draws water in through an opening at the front of the lure and rotates a specially designed propeller inside the body. The propeller produces natural rotational vibrations and flash, while the metallic sound generated during rotation attracts bass holding just below the surface. The rear hook is fitted with a removable elastomer curly tag, providing additional attraction and a moderate level of resistance during the retrieve.
The 75SS is a 75mm, 6g, fixed-center-of-gravity, slow-sinking model with a running depth of 0–0.2m. The basic technique is to let it sink slightly after casting, then retrieve it slowly at the speed that keeps the curly tail moving while maintaining a depth just below the surface, where it may or may not create a wake. Removing the tail allows the lure to be worked through deeper water. The 75S G-Fix is a fixed-center-of-gravity, sinking model weighing 0.8g more than the 75SS. Designed to run at a reference depth of 0.3–0.5m, it is less likely to lose its posture during slow to moderately fast retrieves and is intended to maintain a depth of 1–2m. It comes equipped with a size 10 hook on the front and size 10 tinsel on the rear, allowing anglers to select the appropriate running depth and hook configuration for each model.
