DC Rainmaker lists several manufacturers promising consumer units coming this year in his keynote (don’t have time to find it for you, sorry) here: My 2018 State of Sports Technology Keynote Video | DC Rainmaker
They include :
- Alphamantis (currently used by track based people like Aerocoach),
- SwissSide
- https://notiokonect.com/en/denmark-2
- Aerolab
- RedIsFaster
and a number of others. I have no idea which (if any) are good.
