The Nash Boat Life X Block Marker is a practical tool for marking depth when boat fishing. It features a moulded line clip that keeps the marker secure in transit and locks it firmly at the desired depth. A heavy duty quick change clip allows for fast lead attachment, while moulded recesses around each arm help protect the line. The marker is supplied with a high strength cord and includes pre cut strips of reflective tape. - Moulded line clip - Keeps secure in transit and to lock at the desired depth - Supplied with a high strength cord - Heavy duty quick change clip for lead attachment - Moulded recesses around each arm - Includes pre cut strips of reflective tape
