I have been following SailTimer for some time. IIRC some members here purchased the system previously with poor results. One would think if you were offering a subscription model that the equipment had better be dependable. I know previous version of the wind instrument were not particularly reliable. I did correspond with them several years ago. SailTimer is wireless using BlueTooth v4.0+ which has a range of 300ft. ST is also compatible with Open CPN as well as a connectivity path to NMEA 2000 and 0183 networks. Software runs on IOS and Android. Maybe worth the gamble.
