Auto Fisher Pro is a premium-quality, client-side automation mod for Fabric 1.21.1 designed for players who want a "set it and forget it" fishing experience without the risk of predictable, robotic patterns.

Whether you are playing on a private server or just want to farm treasure efficiently in single-player, this mod handles everything from bite detection to inventory management.

✨ Key Features

🛡️ Anti-Ban Design (Human-like Delays): Unlike basic auto-fishers that click instantly and get you flagged, this mod uses fully configurable, randomized tick delays between casting and reeling. No two fishing cycles are exactly the same, making your actions look entirely natural to server logs.
🎯 3-Layer Bite Detection: Combines the server's caughtFish flag, a Y-level baseline drop sensor, and a velocity spike check. You will catch virtually every fish on the exact tick of the bite.
🔄 Auto-Switch Rods: Never break an enchanted rod again. When your current rod drops to 5 durability or lower, the mod automatically scans your inventory and swaps a fresh rod into your hand.
♻️ Smart Junk Filter: Keep your inventory clean. The mod periodically scans for configured "trash" items (like rotten flesh, lily pads, or leather boots) and automatically throws them away so you only keep the good loot.
⚙️ In-Game Config GUI: Access all settings, sliders, and junk item lists instantly via the ModMenu screen. No need to mess around with text files!
