@Horton I absolutely love the system, but I disagree. After using my system for well over 1,000 passes over the last year my best estimate is at least 50 missed or partial missed passes. The reliability improved significantly after I switched from using my cell phone as a hot spot for the rover to a sim card in the rover, but there were still missed passes. Some were certainly wifi issues at the base station at my dock, some were poor gps reception in the boat, some ended up unexplained, as sometimes it is hard to troubleshoot while you are driving. Many of those "other" causes were likely an unstable voltage source if the boat was shut off at the end of the pass to talk to the skier. Those were improved by using a portable power bank to stabilize voltage. James made a software improvement mid-year that helped isolate if the correction signal from the server was over 60 seconds old with a green indicator and number of seconds old the correction signal was. I think most of the other issues are quality of gps signal at the pylon antenna. I was using the small antenna all year and James recommends the larger antenna for important use, i.e. record tournaments. My larger antenna was delivered today, but it is winter here and I won't know if that completely eliminates missed passes for me for a couple months. Once again I think the system is amazing, but if rules are being developed, the boat crew needs to know what to do if rerides are dictated by out of tolerance passes, and there is no data to tell if it is out of tolerance. Certainly even if the system is functioning flawlessly, a loss in wifi signal to the base for over a minute would cause a missed pass. Does anyone have an ISP that never has a glitch? At my lake, there are lots of ISP glitches, as I am sure is the case at many remote lakes. My recommendation would be no data = no reride.
