Get Your Free Report Explore Free MapWhy Offshore Anglers Struggle
Productive offshore water is hard to find without the right tools. Most anglers are guessing.
Ocean Conditions Change Daily
SST patterns, eddies, and thermal fronts shift constantly. Yesterday's hotspot may be miles away today.
Maps Are Great — Interpretation Is Hard
Ocean maps (including ours) show you what's happening, but knowing which temperature breaks, eddies, and current edges actually hold fish takes years of experience. That's exactly what AI analysis does for you.
Legacy Reports Cost $90+
Other services charge $90 or more per report. DEEPCAST delivers the same ocean analysis at a fraction of the price.
Data Overload, No Interpretation
SST, chlorophyll, currents, eddies, bathymetry, weather — the data is out there, but making sense of it all is the hard part. AI connects the dots across every layer and turns raw data into actionable fishing intelligence.

What's Inside Every DEEPCAST Report
Every report is packed with actionable intelligence — not just raw data.
Annotated SST & Chlorophyll Maps
AI-annotated satellite imagery showing temperature gradients, chlorophyll concentrations, zone boundaries, and current arrows — with key features called out.
Zone-by-Zone Analysis
Inshore (0-20nm), midshore (20-70nm), and offshore (70-100nm+) zones analyzed separately with conditions, structure, and recommendations for each.
Eddies, Fronts & Currents
Every eddy, thermal front, and current pattern in your area is identified and explained — including how they create productive fishing opportunities.
Target Species & Tactics
Species recommendations based on water temperature, season, and structure. Tactical guidance on presentations, depths, and timing.
Recommended Fishing Spots
Specific GPS coordinates for the highest-probability areas based on the intersection of temperature breaks, structure, and current convergence zones.
Downloadable PDF
Every report comes as a printable PDF you can take offshore — complete with maps, analysis, and recommendations. No cell signal required.

Frequently Asked Questions
What is DEEPCAST?
DEEPCAST is two things: a free interactive ocean map and optional AI-generated fishing reports. The map shows live SST, chlorophyll, eddies, currents, and thermal fronts — always free, no account needed. The AI reports go further, analyzing all that data plus weather to give you zone-by-zone fishing recommendations, target species, and tactical guidance for your departure port.
Is the ocean map really free?
Yes — the DEEPCAST map is 100% free, no account, no purchase, no strings attached. You can use it every day without ever buying a report. It shows live SST tiles, chlorophyll-a, ocean eddies with contours, surface currents, thermal fronts, depth contours, and water color labels — all updated daily. Visit sealegs.ai/deepcast/map to explore.
Why would I buy a report if the map is free?
The map shows you the raw ocean data — but interpreting SST gradients, eddy edges, current interactions, and weather windows all at once takes real expertise. The AI report does that interpretation for you: it analyzes every data layer together, factors in weather conditions, and delivers plain-English recommendations on where to fish, what to target, and when to go.
How is DEEPCAST different from traditional SST chart services?
Traditional services give you raw satellite imagery that requires expert interpretation and charge $50-100+. DEEPCAST starts with a free map anyone can use, then offers AI reports that analyze all the data layers together — including weather assessments — and produce actionable fishing plans with specific recommendations, starting at $9.99.
What data sources does DEEPCAST use?
DEEPCAST combines satellite SST imagery (NOAA, Copernicus), satellite altimetry for eddy detection, CMEMS ocean current models, chlorophyll-a concentration data, ETOPO bathymetry, and NOAA weather forecasts. The free map visualizes these data layers directly. The AI reports process all of them together to generate fishing intelligence.
How much does an AI report cost?
Your first report is free when you create an account — no credit card required. After that, a single report is $9.99 (limited time). The 10-Pack is $99.99 ($9.99/report). No subscription required — credits never expire. The ocean map is always free regardless.
What area does each report cover?
Each report analyzes a 150-nautical-mile radius from your selected departure port, divided into three zones: inshore (0-20nm), midshore (20-70nm), and offshore (70-100nm+). The AI identifies productive features across all zones and integrates weather conditions for each.
What is the best SST chart for offshore fishing?
The best SST chart for offshore fishing combines sea surface temperature with other data layers — chlorophyll, ocean eddies, currents, and bathymetry — so you can see the full picture. The DEEPCAST ocean map does exactly that, showing all these layers together in one free interactive chart updated daily. When you need help interpreting it, our AI reports analyze everything and tell you where to fish.
How do ocean eddies help you find fish?
Ocean eddies are rotating bodies of water that break off from major currents like the Gulf Stream and Loop Current. Warm-core eddies trap warm, nutrient-rich water that concentrates baitfish — which draws pelagic game fish like tuna, marlin, mahi-mahi, and wahoo to the eddy edges and thermal boundaries. DEEPCAST tracks every eddy in your region and the AI reports identify which ones are most productive for fishing. Learn more in our Ocean Eddy Fishing Guide.
Do I need to download an app to use DEEPCAST?
No — DEEPCAST works entirely in your browser. The free ocean map and AI fishing reports are all accessible from any device with no app download, no account, and no sign-up required. Just open the map and start exploring.
How does DEEPCAST compare to ROFFS and other satellite fishing services?
Services like ROFFS provide expert-interpreted satellite fishing reports starting around $90+ per report. DEEPCAST takes a different approach: a free interactive ocean map with SST, chlorophyll, eddies, currents, and depth contours — available to everyone, no purchase required. Your first AI-generated report is free with signup. After that, reports are $14.99 $9.99 (limited time) — with zone-by-zone recommendations, target species, tactical guidance, and a downloadable PDF.
