John's Sporting Goods Fishing turns 40+ years of John Martinis's PNW fishing knowledge into a tool you keep on the boat. WHAT'S IN IT • John's curated fishing spots — chinook, coho, pink salmon, halibut, lingcod, crab, shrimp — with the exact rigs, depths, and tide windows that worked for John. • Bathymetric depth contours overlaid on the map — see the shelves, holes, and channels you're fishing. • Live conditions for any spot — wave height, NWS marine outlook, hourly weather, NOAA tides + Hi/Lo events, NOAA current predictions with Flood/Ebb timing. • An AI fishing guide that pulls live conditions, your saved spots, and John's PDFs into every answer. Ask "where should I crab in Area 9 this week?" or "best rig for winter chinook off Possession?". • Drop and save your own spots with catches, bait, photos, and notes — every trip logged builds your personal map. • Track routes with GPS while you fish; the line stays continuous when you switch tabs. • Download John's PDF charts to your phone for use offline at the boat ramp. • Trip Planner — pick a date, location, and target species; get a plan with tide windows, gear, and waypoints. OFFLINE FIRST • Drop pins, log catches, and track routes with zero signal. • Depth contours pre-cache aggressively at app launch around your last fishing area. • Trips you log offline sync to your account the moment you reconnect. WHO IT'S FOR PNW anglers — Puget Sound, San Juans, Strait of Juan de Fuca, North Sound. Both saltwater and freshwater spots are covered. PRIVACY We don't sell data. Location is used only when you ask for conditions or save a spot.
