The Mainline Baits ISO Sweet Pop-Ups (15mm) are the ultimate high-buoyancy hookbaits to tempt wary carp into biting. Thanks to their extremely consistent buoyancy, these pop-ups are perfectly suited for heavier rigs such as the Chod or Hinged Stiff Rig, keeping the rig effective for hours on end. The pop-ups are designed with exactly the same liquid attractors as the Dedicated Freezer and Shelf Life range, making them the ideal and trusted addition to a compact baited area. This subtle yet highly attractive hookbait will not spook even the most cautious fish and offers the very best chance of a quick take all year round in changing fishing conditions.
