The Prestan Clicker for Professional Adult Manikin provides an essential mechanical calibration component engineered to maintain accurate depth feedback thresholds across training fleets. Seated directly within the central compression spine assembly of the torso, this heavy-duty spring-driven module functions as a physical tactile indicator during life support training sessions. It is precision-tuned to provide a distinct, audible clicking sound exactly when the student reaches the AHA-recommended adult chest compression depth threshold of 2 to 2.4 inches.

This replacement assembly features built-in wire leads to integrate directly with electronic feedback monitors, ensuring that physical chest displacement simultaneously signals both the electronic rate monitor and the tactile clicker system.
