Overview
The fish-finder rig features a sliding sinker above a swivel, with leader and hook below. When a fish picks up the bait, line slides freely through the sinker sleeve, giving no resistance. This natural presentation is why it's called 'fish-finder' - fish don't feel anything wrong and eat confidently.

Frequently Asked Questions
Circle hook or J-hook?
Circle hooks are preferred - they result in better hookups and easier releases. Let fish take the bait and come tight without a hard set.
How long should the leader be?
Standard is 18-24 inches. Go shorter (12") in strong current for better sensitivity, longer (36") in calm water for more natural presentation.
What size sinker do I need?
Use the lightest weight that holds bottom. Start with 3oz in moderate surf, go to 5-6oz in heavy current or when targeting long casts.
