Ian Bell of Bell Rigging chose
manufacturer of multiple echo
ultrasonic thickness gauges, Cygnus
Instruments, to supply its latest
Cygnus 2 Hands Free thickness gauge
for a mast survey of HMS Victory. Its
original wooden masts were replaced
by steel and wrought-iron masts,
taken from a ship called the Shah in
the 1880s.

The Cygnus 2 Hands Free uses the
Cygnus-pioneered multiple echo
technique to ensure accurate, reliable
measurements without the need to
remove protective coatings. Therefore,
inspection time and costs are
significantly reduced.
