Features

Everything your leader needs

🌬️

Wind-Aware Leader Length

Adjusts butt, mid, and tippet automatically as wind speed changes. Permit override keeps 10ft minimum regardless of conditions.

🌊

Tide Phase Integration

Incoming, outgoing, high, low — tide phase shapes your casting tip and species activity window automatically.

Water Clarity X-System

Clear, stained, or muddy — tippet X-rating adjusts per clarity. Fluoro vs mono selected based on fly type.

⚡

Shock Tippet Builder

Tarpon, barracuda, and pike get auto-calculated shock tippet: length, pound test, material, and correct knots.
