The Z-Plug #700 Classic series has a 8.5 body and 2 hook/tail with a solid wire at the pull points which aides in preventing the lure from being pulled apart. This has been tested! These baits are Salt Water Tuff and will last a long time. This 700 Classic series Z-Plug will troll to depths of 18 feet or it can be casted and retrieved slowly on the surface as to mimic the action of a wounded bait fish. This bait does not swim as other conventional lures. It does not swim straight , but rather with a darting zig-zag pattern replicating the eratic swimming behavior of a bait fish attempting to elude a predator fish. We use 25-30 pound test line when we use this lure and with the solid wire pull points the Z-Plug should never pull apart. We have tried! These baits are tuff and will last a long, long time.
