The J 38792-A can be used to identify the light spot on a propeller shaft IF the propeller shaft rotational speed is the dominant frequency of the vibration concern. The J 38792-A is equipped with a strobe light trigger wire which can be used with an inductive pickup timing light, J 38792-25, or equivalent included with the J 38792-KIT, or available separately, and in conjunction with the J 38792-A vibration sensor to identify the light spot on a propeller shaft and to help in making a determination as to when propeller shaft balance is obtained.
