Canyon Slayer

Canyon Slayer puts real-time satellite sea surface temperature data in your hands — built by a canyon fisherman, for canyon fishermen. Stop guessing where the temperature breaks are. Stop stitching together NOAA charts, Windy, and forum reports before every trip. Canyon Slayer pulls satellite SST data every 2 hours, automatically detects thermal gradients, and shows you exactly where warm Gulf Stream water meets cold shelf water — that's where the yellowfin, bigeye, and bluefin stack up. WHAT'S INSIDE: • Live SST Heatmap — Satellite data refreshed every 2 hours. Full East Coast coverage from Florida to Nova Scotia with dynamic temperature color scale. • Temperature Break Detection — Automatically finds and rates thermal gradients (moderate, strong, extreme). Tap any break for coordinates, bearing, and run time from your position. • AI Find Fish — Origin-aware AI that factors in your departure port and range to recommend the best reachable break and the hottest bite on the chart, with precise coordinates and trolling advice. Now fleet-aware — it reads where the boats are working. • Live Fleet — Anonymized, real-time positions of the boats working the canyons, so you can follow the fleet to the fish. • Chlorophyll Overlay — NOAA satellite data showing where bait is concentrating. Green water means baitfish, and baitfish means gamefish. • 40+ Named Fishing Spots — GPS waypoints for East Tails, Bigeye Mountain, Hot Dog Ridge, Glory Hole, 17 Fathom Bank, Andrea Doria, and more. • Canyon Boundaries — NOAA/USGS bathymetry polygons for Hudson, Veatch, and Hydrographer canyons. • NOAA Buoy Weather — Real-time wind, waves, and water temp from 6 offshore buoys. • Trip Logging — GPS track recording, catch logging with 15 canyon species, weight, water temp, and photos. • Offline Mode — Download map tiles and ocean data at the dock before heading out of range. • Historical Date Picker — Browse SST data going back to 2025 with daily snapshots accumulating automatically. • Navigation — Nautical mile distances, bearing, and run time estimates to every spot. One-tap to Apple Maps. • MapTiler Ocean — Professional bathymetry base map with depth contours and marine detail. Built for the Mid-Atlantic canyons — Hudson, Veatch, Hydrographer, Block, and Atlantis — with the 200-meter shelf edge contour from Cape Hatteras to Georges Bank. One canyon trip worth of fuel savings pays for this ten times over. ——— Everything in Canyon Slayer is free — including AI Find Fish and Live Fleet. No subscription required.
