Taped underwater markers
Water-resistant threaded markers.
The underwater marker consists of a threaded spherical body covered in a retro-reflective tape that is designed to work well underwater. Ordinary passive markers cannot be used since the retro-reflective properties are lost when the markers are underwater. These markers work both above and under water.
These markers are available in 5 different sizes: 50 mm, 40 mm, 30 mm, 19 mm and 12 mm.
When up close, the taped underwater markers can sometimes break up and be interpreted as multiple markers. For these situations as well as for long time use underwater, we recommend our Super-spherical underwater markers.
Hard, hand-coated markers with threads.

Extra durable markers for underwater use
For situations that call for flat markers.
Our retro-reflective tape can be used in place of ordinary spherical markers. The tape is typically used in situations where you cannot use ordinary makers without affecting the movements of the tracked object. For example when tracking a spinning soccer ball.
The retro-reflective tape is sold by the meter.
