  • How much will Rowcus cost?
    The price has not yet been determined, but will be based on other, less essential electronics for rowing.

  • How does Rowcus warn me?
    Rowcus warns similar to a parking aid on a car with warning sounds. The tones become more urgent the greater the risk of collision.

  • Up to what distance can Rowcus detect objects?
    The maximum distance is 120 meters. However, the distance to which objects can be detected depends on many factors. Metal objects, for example, are seen at a particularly long distance (full 120 m), whereas plastic objects or living beings are only detected at closer range (30-60 m).

  • Does Rowcus warn of all objects in front of me, even if they are not dangerous?
    Rowcus only alerts you if there is an actual danger of collision.The software performs a situation analysis. If a collision is imminent you will be alerted. The signal escalates with decreasing time to collision.

  • How do I know if the device is still active?
    You can assure yourself that the collision warning function is active, by checking the status LEDs facing you while rowing. Furthermore, you can choose to activate a relaxed function confirmation sound that pops up regularly and can easily be distinguished from the alarm signals.
