The omni-directional rod is designed to be mounted from the ceiling of the test kennel and will register a response when displaced in any direction by the head or body of the animal. This was designed for a 5 foot (1.52 meter) high ceiling with adjustable floor clearance of 30.5 - 10 inches (77.47 - 25.4 cm). This has been used as an orienting response for the CANTAB tests to initiate the start of each trial.
