Besides their intended use as commercial trolling weights, these weights also make great temporary anchors for fishing. With the addition of a shackle, they have potential for use as a sentinel (rode rider) for your anchor rode when the wind kicks up and you need that extra bit of holding power.
When used with downriggers, never use heavier weights than fishing conditions require, nor a heavier weight than your downrigger is rated for.
