Drennan Glow Tip Carp Inserts feature our transparent Crystal®-style construction with a 6.6mm diameter straight tube and a stepped 4mm insert in a light green tint to preserve the Glow Tip effect. glow-tip-carp-insert They cast long and straight and have interchangeable, size-engraved bomb weights, which means you can swap to a lighter bomb from another float and put more shot down the line if necessary. A slightly longer stem below the bomb weight also allows a secure grip with a silicone or swivel float attachment. Drennan Crystal® floats and interchangeable Combo Tips have been made by the company simnce the mid-1980s. They are a bit like angler’s Lego, enabling the angler to make alterations to a float according to the conditions. Ensuring that a float from today’s tip fits a tip from years ago takes the strictest manufacturing production controls in our plastics processing plant. We believe the difference in quality of build is obvious to discerning anglers.
