Anchoring Safely for Bottom Fishing
Great instructions on using a ring/anchor rig to bottom fish.
This is a trick we often use when we're tarpon fishing the local bridges in the summer and when we're permit fishing the offshore wrecks and hard bottom. It allows you to pull an anchor using the boat's power without attempting to rip it off the bottom by hand. It works very well and everybody that does any bottom fishing should learn how to do it.
This came from a very cool fishing and outdoors site called BC Outdoors SportFishing TV. There are a few great videos up there and they're all done very well.
