Explaining how Puller groove works
The Puller grove is a new innovative method developed by Viking anchors for retrieving an anchor in case it got stuck with an obstacle on the seabed, rocks, debris, or other boat's anchor chain, and so on.
Our specially designed groove at the base of all of our anchor's shanks is made to hold a heavy short cable or chain lowered around the anchor chain attached to a rope in case the anchor got stuck, it slides all the way on the anchor's chain aligning with the anchor's groove, enabling the anchor operator to pull the anchor forward from under the obstacle and by doing so set the anchor free.
See how puller should be used when needed.
