Calculation methodology

Calculators use transparent geometric and energy relationships. Reel capacity scales with the square of line diameter, while fish finder runtime uses battery energy and power draw. Fish weight is a general approximation, not a species-specific model.

Key rules

Every result must be checked against actual diameters, manufacturer ratings and real conditions.
