After the alarm is confirmed, the user is visually guided first to the point of loss and later, to the MOB. We have developed an intuitive MOB compass that visually guides the user during rescue while requiring zero input from the user.
The rescuing vessel is shown at the center of the compass, while an MOB icon represents the direction to the MOB’s point of loss. The user steers the rescue course shown on the screen until the icon is right in front of the onscreen vessel image. The icon turns green and gets bigger as you make the approach. There’s no chart reading involved; it’s simple and intuitive.
Once the rescuing vessel gets close to the point of loss, the system initiates a homing feature, similar to what a rescue helicopter would use. A continuously updating search perimeter is drawn around the point of loss, based on the amount of time that has passed to account for drift caused by current and wind. While in the water, the beacon will rapidly emit an emergency signal.
Because of a Bluetooth signal's poor performance in water, the phone will only receive this signal when it is in close proximity to the beacon. Once received, the app will notify the user and advise them to try to establish vocal and visual contact with the MOB.
