ABSTRACT:
A visual device placed on a water ski that enables easy detection of the ski in various water and weather conditions. A reflective red flag attaches to a flexible spring that is attached to a rotator. A second spring attached to the rotator is connected to a counterweight to balance the flag. The rotator is rotatably coupled to a bracket that attaches to a water ski. In use, the device bends out of the way as to not interfere with the performance of the water ski. When the ski is not in motion, gravity causes the counterweight to move the flag to an upright position to allow visual detection of the ski.
