The Airmar DX900+ Multilog Smart™ Electromagnetic Speed Sensor Thru-Hull NMEA0183 is the backbone of modern boat instrumentation, delivering accurate vessel speed and water-referenced data to your chartplotter and marine electronics suite. Built for serious anglers, cruisers, and commercial operators who demand reliable speed telemetry in all conditions, this electromagnetic sensor eliminates the mechanical drag and fouling issues that plague traditional paddle-wheel designs. Once you've run a quality speed sensor, there's no going back—accurate knot-per-hour readouts directly influence trolling speed control, fuel efficiency calculations, and safe navigation in shallow or heavy-traffic waters.
The DX900+ uses Airmar's proven electromagnetic sensing technology to measure water flow without moving parts, making it immune to weed, seaweed, and debris that clog conventional impeller sensors. The thru-hull installation ensures flush integration with your hull and minimal hydrodynamic disturbance, while NMEA 0183 output provides plug-and-play compatibility with virtually every modern marine display unit on the market—Garmin, Humminbird, Raymarine, Furuno, and beyond. Weighing just 1 lb, the compact form factor fits easily into existing transducer shoots or can be integrated into new builds without structural complications. The Multilog Smart™ feature set delivers speed-of-advance data (SOG and SMG), crucial for precise trolling patterns and drift fishing where maintaining exact boat speed separates productive days from empty ones.
Anglers targeting stripers, walleye, pike, and pelagic species rely on the DX900+ to maintain consistent trolling speeds—critical when deploying crankbaits or live-bait rigs that have optimal working depths tied to boat velocity. Cruisers and offshore operators benefit from the sensor's durability in saltwater and harsh marine environments, where reliability directly affects safety and voyage planning. Installation pairs seamlessly with multifunction displays (MFDs) and legacy single-function instruments via standard NMEA connections. For anglers upgrading aging systems or retrofitting vessels with modern glass, the DX900+ represents the entry point to speed-derived fishing intelligence that improves catch rates and reduces wasted fuel chasing inefficient presentations.
