Spearfishing Copilot answers one question: where and when should I dive? It is not a weather app with a fish on it. It reads marine forecast data for the spots near you — swell height and period, wind, current, water temperature, rainfall over the past 48 hours and the depth of the seabed — and turns it into a single dive score from 0 to 100, a best time window, and an expected visibility range. THE SCORE IS DETERMINISTIC The same inputs always produce the same number, with fixed weights: visibility 30%, wind 20%, swell height 15%, swell period 10%, current 10%, water temperature 5%, rain and runoff 5%, and your own history at that spot 5%. Nothing is generated, guessed or smoothed to look better than it is. Every score opens up to show which factor cost it what. VISIBILITY IS A RANGE, NOT A PROMISE The estimate starts from a clear-water baseline and subtracts what actually spoils it:…
