Heavy Duty Low Resistance Buoys LR-1 red Diameter: 240 mm Length: 470 mm Buoyancy: 13 kg Eye diameter: 28 mm Circumference: 750 mm DAN-FENDER is pleased to introduce its new range of LOW RESISTANCE heavy-duty marker buoys (LR-Buoys). Designed for professional fishing, the special spherical body of the buoy makes retrieval much easier, faster and safer! These low resistance buoys significantly reduce drag compared to standard round marker buoys, which is very important when working in rough seas when retrieving, for example, pots. The 4 sizes are manufactured to the highest quality, and all come with DAN-FENDER's well-known black, solid rope eye. The valve used is DAN-FENDER's well-known replaceable metal/brass spring valve. All buoys are tested for leaks in the water tank before being packed. The LR-4 comes standard with a recessed stainless steel ring for maximum strength! (optional for all sizes, contact us). For decades, DAN-FENDER's heavy-duty buoys have been the preferred net and buoy marker for professional fishermen who demand durable and long-lasting products. With this new range, we can now satisfy even more fishing customers around the world. The maximum load on the buoy should be 60% of the specified buoyancy in the diagram below.
