An accurate optical tachometer. Reads directly from reflective
strips fitted to the propeller and is used whenever an accurate
check of RPM is required. Will usually read propeller RPM in
sunlight without reflective strips. Used to confirm accuracy of
RPM readings of standard instruments.
Commercially available tool designed for high-
torque applications on small nuts. Also allows the
use of a torque wrench in inaccessible locations.
