A wading staff/stick comprises a hollow tube D (made from, for example aluminium) and a lanyard/strap A made of stainless steel rope, which may be drawn into the inside of the staff/stick when not in use by means of a lead or metal weight F secured to one ends of the rope. When in use the lanyard may be pulled out of the staff through a hole in the top of the staff L, coming to a stop when the weight is abutted against the inside of the top of the staff. The top two thirds of the tube are perforated E, allowing water to freely pass through it and reducing the water pressure on the top half of the staff when it is submerged in a flowing current. The bottom of the staff is weighted with lead K to provide ballast and a hole H is provided above a base of the staff to allow water to drain from the staff. The bottom section of the staff is covered in a heavy plastic tube M to avoid rock damage to its external finish. |
