The Ridgemonkey RotaBlock Marker is a buoyant marker float designed to hold its position on the water. Its super-buoyant ABS construction keeps it visible and afloat, while a self-levelling anchor system helps it sit correctly in the water. The float is compatible with illuminated MarkaLite stems, which are available separately, and features a protected registered design. Reflective strips aid in locating the marker with a headtorch at night on the Mini and Midi versions. - Robust ABS - RotaBlock body - 2x Reflecta Stems (Maxi only) - 10m/33ft cord (Mini and Midi), 20m/66ft cord (Maxi) - Neoprene carry case Note: anchor weight not included.
