1kg Fins4u own design (made by HS Drop) drop weight, with belt attachment
Clip your line to the weight/anchor, then with the belt attachment slide the weight onto your weightbelt. Then when you need to mark a spot you can drop the weight onto the mark and fish away!
Really pleased with the quality of this product, it arrived quickly as always, and I really enjoyed using it for the first time today not that noticeable on my belt but heavy enough to hold the bottom with my bodyboard+flag attached
