CV7 is an evolution of the well known CV3F ultrasonic wind sensor

Lighter, more compact and less energy consumption, this model is configurable and particularly well suited to sailboats.
This sensor can be used connected to a PC and any system featuring an NMEA® input port and specific pieces of equipment using conventional formats.
In PC mode, this bidirectional sensor can be set up for angle correction, damping, units of measure and interface formats.
All LCJ Capteurs are designed and manufactured in the Nantes region in France where they are fully tested throughout the manufacturing process.

CV7 is a wind sensor designed for sailboats. The mounting arm is designed for installing the unit of any mast-head.
