Sonar Guide detects obstacles in the user’s path of travel below waist level at 3 different distance settings, customizable at request. The peripheral obstacles outside of the sensor’s range will not be detected.
Sonar Guide will detect changes in elevation (drop-offs and step-ups) of 3 or more inches.
When an obstacle is detected, the alert LED will turn red and you will hear a voice in the headset say “Obstacle Right”, “Obstacle Left”, or just “Obstacle”.
When drop-off or step-up is detected, the LED will turn yellow and you will hear a voice in the headset say one of the following: “Dropdown Right”, “Dropdown Left”, “Step-Up Right”, “Step-Up Left”, or either just “Dropdown”, or just “Step-Up” if both units detect at the same time (even if an obstacle is also detected at the same time, only the step-up is announced).
