NASA Electromagnetic EML-2 Lo | 4Boats

EML-2 electromagnetic speed log measures boat speed through the water with no moving parts, offering robust, linear performance and direct NMEA-0183 output.

• No moving parts — electromagnetic sensor mounted beneath the hull
• Speed range: 0.37–74.1 km/h (0.2–40 kt)
• Resolution: 0.19 km/h (0.1 kt)
• Provides boat speed through water plus trip and total distance
• Sensor generates an alternating magnetic field and measures the resulting electric field
• Control box converts sensor signal to speed, trip and total distance
• NMEA-0183 output for integration with compatible displays
• Robust construction with excellent linearity and accuracy

Compatible with most NMEA-0183 displays; professional installation recommended.
