Know how expensive plastic buoy markers are from the catalog? Ridiculous !
So, I happened to be at the dollar store (dragged there once a week by the wife) and saw a box of foam bop ’em tubes for kids, used in the water. Seeing as how they float, why not cut a 7″ section, wrap about 30′ of old stiff braid I’ll never use and attach a weight to that.
Note: the screws are secured on one side only with duck tape for weight so the rolling buoy doesn’t keep unraveling more string when a wind blows the buoy.
I keep 4 on board in a gallon size freezer bag and mark mid lake structure easily. If I leave one behind (which is inevitable) only to find someone made off with it, at least the cost is less than a few bucks to make another.
