Folding Anchor - 1.5 lbs

I use this size on my Prowler 13 while I scuba dive. It has always been there when I finish. I put a short (1ft) piece of galvanized chain on it, seems to help keep it pulling on the reef rather than up. I also do't have to use quite as much scope with the chain in use. The collar does not keep the flukes in very well, but it stays open well. I have not used it much in sand, but I would imagine it works pretty poorly in sand/mud. The only thing holding you there is the weight of the anchor in sand, so you may opt for the larger size if that is where you fish.
