How It Works
Physics-Based Calculations
Input your bait specifications and water parameters to instantly reveal terminal velocity, time to depth, and horizontal drift caused by current. Every value updates in real time as you adjust variables, showing exactly how adding weight or changing shape affects the entire descent profile.
The shape analyzer breaks down drag coefficients for different lure geometries. Compare streamlined jig heads against flat spoons or cylindrical tubes to understand which design fights current resistance and which prioritizes flutter action. Each shape receives a precise Cd value from 0.47 for jig heads to higher coefficients for irregular forms.
Multi-layer current modeling accounts for varying flow at different depths. Surface current might push one direction while bottom current flows another. The calculator processes both vectors, showing the curved path your bait actually travels instead of assuming straight vertical drop. See exact landing coordinates relative to your starting point.

Built-In Arsenal
Real-Time Calculator
Input bait weight, shape, and water conditions to instantly calculate terminal velocity, time to target depth, and horizontal drift. Every parameter adjustment updates all values in real time, showing the complete descent profile from release to bottom contact.
Shape Analyzer
Compare drag coefficients across jig heads, spoons, tubes, and custom geometries. See how streamlined designs create minimal drag for quick sinks versus flat profiles that maximize flutter action. Includes 3D bait visualization with Cd breakdowns.
Multi-Layer Current Modeling
Account for varying flow at different depths. Surface current might push east while bottom current flows south. The calculator processes both layers, displaying the curved path your bait actually travels with top-down view and landing point coordinates.
Material Comparison
Understand how tungsten sinks differently than lead at identical weights. Compare density, water resistance, and descent profiles across materials. The weight optimizer finds the exact mass needed to reach your target depth within a specific timeframe.
Calculation History
Every analysis saves automatically with full environmental parameters, bait configuration, and results. Review past sessions, compare performance across different conditions, and track which setups consistently reach target depths accurately.
Local Processing
All calculations run locally on your device with zero external data transmission. No account required, no cloud sync, no tracking. Your fishing data stays private. Works offline once installed.
