EVERY SATELLITE SST PASS, WITH THE BREAK ALREADY DRAWN Fishare draws every satellite sea-surface temperature pass of the last 72 hours as the satellite saw it, over every coast we cover, checked for new passes every hour. Clouds stay as holes, and the temperature break is found and labelled on the pass for you, so the edge where bait stacks up is marked before you start reading color. • 24-hour and 72-hour cloud-free composites for the days the passes don't line up • Hourly geostationary frames from GOES and Himawari-9 • Up to 30 days of pass history per region • Chlorophyll by satellite day, with a 3-day composite • Sea-surface height with labelled contours • Modelled surface salinity, daily • Water temperature at 25, 50, 75, 100, 150 and 200 m, each depth checked against Argo float profiles • A 5-day SST forecast on the same map as 7 days of playback • The classic spectral ramp in °F or °C, with a drag range and isotherm spacing • Your waypoints pasted or imported as GPX; every mark becomes a GO TO with bearing, distance and ETA, and your marks stay on your phone • One tap to share the pass you are looking at with your crew • A per-species habitat score on the same map, re-scored every hour on the freshest pass ONE SUBSCRIPTION, EVERY REGION Fishare Pro opens all 15 regions we cover, with the layers each one carries: the Northeast canyons and the Gulf, the US West Coast, Hawaii, Baja and the Sea of Cortez, the Caribbean, the eastern tropical Pacific, the Canadian Maritimes, the whole Australian coast, New Zealand, the south-west Pacific, Japan, and the UK and Ireland. No per-region licence, no buying the coast one piece at a time.
