Electronics
Fishfinders, chartplotters, radar, and sonar — what actually matters offshore, explained by someone who works in IT.
Boat Networking Explained: NMEA 0183, NMEA 2000, and Marine Ethernet
What NMEA 0183, NMEA 2000, and marine Ethernet (Garmin Marine Network/BlueNet) actually are, what data runs on each, and how they connect together through your chartplotter — plus links to a full setup guide for each.
Marine Ethernet Setup Guide: Garmin Marine Network vs. BlueNet
Legacy Garmin Marine Network vs. the newer Garmin BlueNet Gigabit Ethernet system explained — cabling, the PoE isolation coupler requirement for third-party cameras, backward compatibility, and what actually needs this network.
NMEA 0183 Setup Guide: Wiring, Multiplexers, and What Still Uses It
How NMEA 0183 wiring actually works, why you can't just splice two talkers together, what a multiplexer does and when you need one, and typical data carried on 0183 versus NMEA 2000.
NMEA 2000 Setup Guide: Backbone, Drops, Termination, and Power
NMEA 2000 wiring explained — backbone and drop topology, why you need termination resistors at both ends, connector types, power budgeting with LEN, and a real starter kit for adding a device.
Garmin ActiveCaptain App: What It Actually Does For You
The Garmin ActiveCaptain iOS app broken down — syncing waypoints, chart updates, remote Helm control, network-wide firmware updates, and the crowd-sourced marina/anchorage data most boaters never open.
Garmin Transducers: How to Pick the Right One for Your Boat
How to match a Garmin transducer to your chartplotter tier, boat, and target species — GT-series naming decoded, CHIRP vs ClearVü/SideVü vs Panoptix LiveScope, mounting styles, and real specs off my own boat.
Garmin Chartplotter Lineup: STRIKER, ECHOMAP, and GPSMAP Explained
Garmin's three chartplotter families explained at a glance — STRIKER, ECHOMAP, and GPSMAP — with who each one is actually built for, and links to a full model-by-model breakdown of each series.
Garmin ECHOMAP Compared: UHD2 vs. Ultra 2
Garmin's ECHOMAP lineup broken down — UHD2 versus Ultra 2, real sizes and prices, sonar power differences, and which one actually fits a bay boat or nearshore center console.
Garmin GPSMAP Series Compared: x3, 10x2/12x2, 8000, and 9000
Garmin's GPSMAP lineup broken down model by model — the x3 touchscreen series, the keyed 10x2/12x2 line, and the 8000/9000 glass-bridge flagships — with real sizes, prices, and which boat each one actually fits.
Garmin STRIKER Compared: Cast, Plus, and Vivid
Garmin's entry-level STRIKER lineup broken down — Cast, base STRIKER, STRIKER Plus, and STRIKER Vivid — real sizes and prices, and which one actually fits a kayak, jon boat, or budget backup unit.
VHF/DSC Setup: Why It's Your Real Safety Net Past Cell Range
How DSC distress calling actually works, why it's useless without GPS wired in, how to get a free MMSI number, and the real range difference between a fixed-mount VHF and a handheld.
Adding a Garmin MSC 10 Satellite Compass to an Existing Autopilot
Why a GPS-based satellite compass beats the magnetic compass built into a Garmin Reactor course computer — and the one situation where it still needs to fall back to magnetic, which is why it still requires calibration.
Offshore Weather Apps: NOAA, Fish Weather, and Windy, All Three
The weather app stack I actually use before every offshore trip: NOAA's marine forecast for the official word, Fish Weather for a fast buoy-based glance, and Windy for saved spots with wind, wave, swell period, and storm tracking.
Choosing an Offshore Fishfinder/Chartplotter: An IT Guy's Honest Guide
CHIRP frequencies, transducer choice, NMEA 2000 networking, and where the marketing ends — how to spec offshore electronics without overpaying.
Garmin Force Kraken on a 31-Foot Boat: Install and 90" vs 110"
An owner's review of the Garmin Force Kraken trolling motor on a 31-foot center console — MFD integration with no remote, waypoint spot-lock, and choosing between the 90 and 110 inch shafts.
Starlink Mini Offshore: Internet 60 Miles Out Without Yacht Pricing
Running a Starlink Mini on a fishing boat — how Roam Unlimited really behaves past 10 miles, the ocean data toggle at $2/GB, and why Global Priority is overkill for anglers.
