Drennan Giant Crystal Fishing Float, New and improved for 2016, Drennan Giant Crystals are larger in diameter than Insert Crystals but still feature a sensitive insert for enhanced bite detection. These floats have a 5.75mm body with an interchangeable 3.2mm insert. The tips are available in red, orange or yellow and feature our ultra-bright Glow Tip paint finish to maximise visibility in all light conditions. These transparent Crystal floats have a subtle light brown tint and are built and engineered in Drennans own factories to ensure quality and consistency. Giant Crystals are available in seven sizes from 1g to 4g. The wide selection means that they are suitable for close-range and distance work on stillwaters and rivers. As with all Drennan wagglers, these floats are designed to be attached bottom-end only via the base eye or with a Float Attachment.
