If a Dry Suit Dive is conducted during the PADI Advanced Open Water Diver or Advanced Plus Course, it may be counted toward the certification requirements for this speciality at the discretion of the instructor conducting the Speciality Course.

Completion of a confined water dry suit training session is required of
student divers never having used a dry suit prior to enrolling in a PADI Dry
Suit Speciality Course.
This confined water training session must be completed prior to making the first open water training dive of this Speciality Course.
Additional confined water training may be added at the discretion of
the instructor conducting the Speciality Course. It is highly recommended, but not required, that students use the same type of dry suit on the open water dive as used during the confined water session.
Upon completion of this session, students must be able to:

• don and doff a dry suit with the aid of another diver.
• demonstrate the procedure for conducting a buoyancy check while wearing a dry suit.
• perform a feet first descent, without the use of a line.
• demonstrate neutral buoyancy by hovering for 30 seconds while near the bottom.
• demonstrate the ability to maintain neutral buoyancy, near the bottom, when both the inflator and deflator mechanisms on the dry suit are depressed.
• demonstrate an ascent from the bottom, at a rate no faster than 18 m/60 feet per minute.
• remove and replace, on the surface, both the scuba unit and weight belt.

This course covers the knowledge and techniques of dry suit diving. The
minimum number of recommended hours is 12 with emphasis placed on the
use of dry suits - operation principles, care and diving techniques.
To conduct a Dry Suit Diver Course, the following is to be included:

• the planning, organization, procedures, techniques, problems and hazards of dry suit diving.
• proper procedures for buoyancy control.
• ascent and descent technique training.
• routine, user-level, preventative maintenance and performance checks on dry suits.
