Nasa Marine Target Wireless Wind Speed and Direction System

Nasa Target Wireless Wind System

All instruments in the Target Range come complete with sensors or transducers as appropriate and all necessary fittings. They are designed to run on 12v supply, but due to the very low power consumption there is no reason why they cannot run off dry batteries. They provides accurate readings for owners of sailing craft and powerboats alike.
Designed for long term maintenance free performance, the NASA Wind Speed and Direction instrument is robust in manufacture and simple in operation. Initial set up aligns the boats head with the wind indicator, so the masthead unit can be mounted in any convenient location and is not bound to fore ~aft mounting.
