Easy to mount, easy to use  

Just unbox it, screw it to your favourite setup or to one of our mounting accesories, download the app....and ready! Its simplicity has encouraged many users to find its own way of using it and  our "open protocol" policy has definitely helped.  Many app developers and OEMs have made the Ultrasonic portable compatible: weather apps, ballistics, marine, ...one piece of hardware but many different apps/displays!

ZERO cable tolerance: Wireless and Self Powered

• No power cords: its solar cell makes the Ultrasonic Portable self powered: Up to 29 days of continuous operation in the dark and over a year on sleep mode.  

• No data wires, but connectable to your network: its bluetooth connection avoids the hassle of wiring it to a display. Still, if you want to connect the Ultrasonic Portable to a display or network, you can use one of our gateways: the NMEA Connect Plus gets the Portable Bluetooth signal and converts it to a wired or NMEA0183 or NMEA2000 signal. It also relays the Bluetooth signal and casts NMEA0183 data via WiFi.

• • " Thanks again for nice device"- Alexander Babichev

     "I added new feature to my app: now my friends can view me on map while I'm sailing.  Most interesting part that it shows not just position, but also wind and heel angle coming from Ultrasonic Portable.  My parents are very happy to watch my sailing session because now they can clearly see my mast is still pointing to skies, not bottom :)
    It is very exciting to use app as instruments panel, but often my hands are busy while sailing.  So I decided to abandon my old instruments and make "smart" instrument panel.  I purchased inexpensive Android-powered e-ink reader.  It hasn't GPS and Bluetooth, but it runs Android and has USB port.  I used ESP32 MCU to connect Ultrasonic via Bluetooth, GPS via serial bus and emulated USB serial device for e-ink reader.  While I still need to make pretty case, it works amazing, specially when sun is bright.  I'm very happy with it :)
