If there is one item that every (saltwater) angler should have on them at all times, it's a weighted treble hook. Whether you're fishing the back bays, ocean surf or way out in the canyons, the snag hooks can come in handy, and lead to a memorable catch.
Snagged baits can be kept for later use, brought to another location or used live right where you snag them. If you're going to live-line the baits, the best practice is to transfer the bait onto a more catch-and-release-friendly hook, like a circle or J-hook, but in some instances, particularly when surfcasting, "snagging and dropping" is the only way to keep your bait in the strike zone.
Your choice of hook size will be based on bait size you are snagging and the loading weight possible on your fishing rod.
These snag hooks could be used to assist with the retrieval of objects on bottom. The larger sized hooks can be attached to a heavier line and used as a Pier Gaff.
Just be cautioned, simply possessing one of these hooks on some freshwaters, like the Great Lakes tributaries, could get you into trouble, so make sure you're clear on the local regulations before possessing or swinging one of these grappling hooks.
The WTH Weighted Treble Hooks are made with quality plated hooks suitable for use in Freshwater or Saltwater. Don't confuse these with the cheaper bronze snag hooks!
