The "Wanchor"/Water Anchor

This is for use in potholes where there is water but no sand. It incorporates the Sandtrap with the Wanchor. The pull is very easy as there is only plastic coated cables running through loops to empty the water. Once it is emptied, then the rap rope is used to retrieve the Sandtrap/Wanchor. The Wanchor is attached to two of the webbing straps of the Sandtrap with small rapides
It can be filled by immersing in water or filling through the top with potshots of water. It holds 15 gallons of water, equal to about 130lbs of weight. More than enough. The top does not even have to be closed and secured by the cables to use in the Taco configuration, only the bottom rolled and secured by the one cable.
