This consists of a hard plastic float on the end of a 50' line. The floats are ordered special and are good to 600' and can float 40 lbs. The line has duster material woven into it. It does a great job of attracting Amberjack and may help in populating the reef. It uses a reef unit to anchor it or can be deployed on a weight. Great price, the float alone is worth more than $150. Sold as an add on or do it yourself with a weight. Mail orders accepted. They are not legal everywhere, so call and talk to David before ordering.
