The new revolutionary instrumentation for sail boats.

The first instrumentation for regatta and cruise that allows to decide which sensors and instruments place on your own boat, basing on your needs, in total freedom and in any moment.
The best solution for expand, organize or install on your boat the most advanced and simple instrumentation system in the world.
Which sensors to be mounted on board?
esa Instruments automatically manages the data coming from the boat, transmitting via Wi-Fi to iPhone, iPad, iPod touch or to the onboard displays.
Freely choose which sensors and display to mount
The heart of the system, the processor ESA INSTRUMENTS BOX

Esa Instruments Box is able to process al signals (included analogues ones) coming from the sensors, and makes them available to the users, with all dedicated settings, calibrations and damping desired
Thanks to its high computational frequency, the processor is the ideal choice the instrumentation governor, being the collector for the signal coming from the sensor.
Mast repeater Wind, compass and GPS sensors Chartplotters
Take Control of your data

Advanced Settings just one click away.
Thanks to the dedicated app Esa Instruments it is possible to control every aspect of the instrumentation in an easy and intuitive way. All advanced settings of sensors and data, like offset, damping, gain are easy to set and than are made available to every output device: chartplotters, displays, mobile devices.
Discover all the options available to precisely customize your data on board, like:
- Correction Table of TWS e TWA
- offset Wind Angle
- offset Compass
- boat speed gain at 2 levels
- damping for each data
All data calibrated in this way are processed by esa Instruments box and sent back in the network: in nmea0183, nmea2000 and wi-fi.
