Mark fishing spots quickly and easily: simply attach the chosen weight, lower the floating RotaBlock Marker from the boat, and the self-leveling RotaBlock system will automatically find the correct depth. Once the RotaBlock has stabilized, unwind another half meter of cord to counterbalance wind and waves, lock the body with the sliding pin, and leave the marker permanently in position until the end of your session. Supplied complete with a 10-meter (33ft) anchoring cord, 2 removable ReflectaStems (Maxi), and a neoprene case. Compatible with illuminated MarkaLite stems, available separately.
