This is the best option for finding jewelry chains, as the metal detector does not detect these small targets well. This rake is made of stainless steel AISI-304 plates -2 mm. All parts are made of stainless steel. The rake can be used for long-range casting into the water. The photo shows a plastic bottle, it serves to make the rake fall into the water with the teeth down.
Internal diameter of the pipe for attaching the handle - 28mm. Rake width -550 mm, tine -17 mm. You can change the angle of the rake in 4 positions. This rake is universal and well disassembled for transportation. You can also make them heavier, they have a screw cap where you can pour stones or lead.
I have many other scoops for sale.
