Veratron 3-3/8" (85mm) OceanLink® GPS Speedometer - Black Dial & Bezel (0-70 K/MPH/KMH)

The Veratron 3-3/8" (85mm) OceanLink® GPS Speedometer with black dial and bezel is a marine-grade instrument that transforms how you monitor vessel speed and performance. Designed for serious boaters and mechanics who demand accuracy in real-time speed telemetry, this GPS-based speedometer eliminates the guesswork inherent in traditional paddle-wheel or pitot-tube designs. Whether you're fine-tuning propeller performance, validating hull modifications, or ensuring compliance with speed zones, this instrument delivers the precision data you need at a glance.

OceanLink® GPS technology provides independent speed measurement unaffected by hull buildup, prop damage, or pressure-line fouling—issues that plague mechanical speedometers. The 85mm bezel fits standard instrument panels and 2-inch gauge openings, while the 0–70 K/MPH/KMH dual-scale dial allows seamless operation in either metric or imperial units. The black dial contrasts sharply for daylight and low-light readability, and Veratron's reputation for sealed construction means this gauge survives salt spray, vibration, and harsh marine environments without calibration drift. Internal GPS processing outputs clean analog signals to the gauge movement, ensuring needle response matches actual vessel velocity with zero lag.

This speedometer suits powerboat builds, retrofit instrumentation clusters, and performance diagnostics where you need a standalone speed reference independent of engine ECU data. Mechanics upgrading older vessels or installing custom dashboard arrays will appreciate the compact footprint (3-3/8" face diameter) and plug-and-play wiring to OceanLink® network systems. Installation requires basic panel cutout work and low-voltage harness connection to your GPS transducer; no complex calibration or software intervention needed. Ideal for twin-engine rigs, center consoles, and high-performance craft where documenting true water speed is critical for warranty verification or competition record-keeping.
