The only way to get one is through this Kickstarter campaign. People who back the project on Kickstarter get to have the very first FloatHubs available. Click on the ‘Back This Project’ button on the right hand side of the campaign page.
Yes, just increase your pledge amount by the level of the award (i.e. $149, $298, $447, etc.). We will cover any additional shipping costs on multiple unit orders, but they must all be going to the same address.
You do not need to pay any subscription to use FloatHub. Both the WiFi-NMEA gateway and sending vessel data to the floathub.com website work without any payment, credit card account, etc. To store more than the last 24 hours of data or to send text alerts (in addition to free email alerting), you have the option to pay for enhanced service.
