The logger has a radio interface for supplying data to the coach in real-time. The radio link has a range of 100-150m, but other ranges may be supplied upon request. The coach typically would be following in a launch on a car, viewing the data on a lap-top.
A number of visually eye-catching displays help to render the characteristics of each stroke so that the coach can quickly assess changes in the crew.
The same mechanism can be used to hook up the system in a rowing tank, where a wired link to a PC can be used to show rowers their curves in real-time.
