"Alternatively, the boat hook head (57343) is also available. It is lighter, reinforced for extra strength, with a wider opening, which allows you to capture objects more easily. This hook head can be used with the plain (57340) or telescopic tubes (57341 - 57342 ), which are sold separately. All Lalizas boat hooks are manufactured by the highest standards. The hooks are made of Nylon and the poles of high quality anodized aluminum, for longer life."
