Drennan Pellet Wagglers are available in both loaded and unloaded versions.
The translucent body ensures they are unobtrusive in the water and perfect for wary carp feeding in shallow water. The unloaded versions are normally fished with locking shot placed either side of the float stem. The loaded versions are best fixed onto the line with Drennan Grippa Stops either side of the float.
In both cases, a Drennan Float Attachment will enable you to swap float sizes quickly and efficiently without having to rethread the waggler onto the line.
