OMS Scuba
Cylinders
OMS® is the Company that
listens to its customers. Over the years our diver base has
overwhelming indicated a preference for high pressure/high volume
cylinders of the same capacity as the OMS® low pressure
cylinders, coupled with the superior abrasion and corrosion resistance
of a Hot Dipped Galvanized cylinder .
