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 (Canyon Slayer Pro) — 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 (Canyon Slayer Pro) — Real-time AIS positions of the boats working the canyons. Tap any boat for its name, speed, course, and last fix, then route straight to it. • Crew & Chat (free) — Make a crew, share the code, and see your buddies' boats live on the map. Crew threads, open canyon rooms, and Dock Talk. Position sharing is opt-in and foreground-only. • The Spots Tab (free) — 79 named marks with depths, coordinates and Loran TDs, sorted by distance with bearing and run time. • 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. ——— FREE FOR EVERYONE, ALWAYS: the offshore map, live SST heatmap, temperature break detection, chlorophyll overlay, NOAA buoy weather, 40+ named spots, canyon boundaries, trip logging with photos, historical dates, navigation and offline charts. CANYON SLAYER PRO adds the two features that cost real money to run — AI Find Fish and Live Fleet. Every angler gets a 7-day free trial of both, whether you just downloaded the app or have had it since day one. • Canyon Slayer Pro Monthly — $17.99 per month • Canyon Slayer Pro Annual — $149.99 per year Canyon Slayer Pro is an auto-renewing subscription.

THE BITE MAP A color-coded bite forecast for your target species around your home port. Pick a species and a port, and the map shows where conditions line up. OCEAN DATA LAYERS - Sea Surface Temperature (NASA MUR, 1km) — find the Gulf Stream wall and temperature breaks - Chlorophyll-A (VIIRS, 1km) — water color and productivity, where bait stacks - Animated wind field with speed and direction - Ocean currents and front convergence - Weather radar CHARTS AND BOTTOM STRUCTURE - NOAA BlueTopo bathymetry in US waters - Ocean Bathymetric and Seafloor Relief basemaps - Depth contours with readings in feet and fathoms - Thousands of charted wrecks, reefs, ledges, lumps, and canyons - Hundreds of public boat ramps - LORAN-C TD lines for captains working from legacy numbers - Import and export waypoints as GPX FORECASTS Tap any waypoint for a 6-day forecast with wind, gusts, seas, and tides. AI CAPTAIN'S BRIEF A written pre-trip read on conditions for your port and target species. MY CATCHES Log a catch and the app auto-fills ocean and weather conditions from the same sources shown on the map. After a handful of entries, a Your Patterns panel summarizes the conditions that show up most often in your successful trips, and can break it down by species. AI CATCH MEASURE Offline camera measurement with a weight estimate. VIRTUAL TACKLE BOX Lure and bait recommendations based on current conditions. REGULATIONS AND CLOSURES See National Marine Sanctuaries, no-take reserves, HAPCs, and groundfish closures on the chart, each with the rules and a link to the official regulation page.
