Learn to Scuba Dive in Cozumel!
NAUI Scuba Diver
This entry-level class consists of academic development
via self study and instructor led classroom sessions, a series of
confined water dives to help learn skills and build confidence and
adventurous training dives. If you're looking for a quality Scuba
Diving class that offers something more than a quick gloss-over of
this is it. Classes are available per request.
Scuba Diver is the NAUI entry level scuba certification
course.It provides the fundamental knowledge and skills to scuba dive.Upon
successful completion of this course, graduates are considered competent
to engage in open water diving activities without supervision, provided
the diving activities and the areas dived approximate those of training.
PREREQUISITES FOR ENTERING THE COURSE
- Age. Minimum is 15 years for Scuba Diver certification.
(Junior certification for ages 12 –14 years is allowed).
- Diver Certification. None required.
- Prior Training. Students who hold credentials
from the NAUI Passport Diver Program may, at the discretion of the
instructor, be awarded credit for skills and knowledge acquired.
• Ratios. Standard ratios apply. (for DE
the ratio is no more than 4 to 1). Specific open water supervision
policies are detailed below.
Academic - 14 hours estimated.
Practical Application - 17 hours including not less than
10 water hours.
• Open Water Dives. The minimum number of open water dives is five. They
may be all scuba dives or one skin dive and four scuba dives. No more than three
scuba dives may be made on a single day during the course. Open water training
may be completed in two days with a skin dive and two scuba dives on one day
and two additional scuba dives on the other day. All open water training must
take place during daylight hours.
• Daily Hours. No more than eight hours of training may be conducted during
any one day.
• Depth. Sixty feet (18 m) is the maximum depth for any open water training
dives during the course.
• Escorting. Certified assistants may escort students during surface excursions
and exits, ascents and descents and may temporarily attend to remaining students
while the instructor conducts a skill with other students. The maximum number
of students allowed per escort during underwater tours is two.
• Touring. During the second or subsequent open water dives, pairs of students
may be escorted on tours. The instructor must evaluate the following skills for
each student before that student is allowed to tour with a certified assistant:
– Remove, replace and clear a regulator.
– Regain primary regulator from behind the shoulder.
– Mask clearing, including removal and replacement.
(In cold water environments when mitts and hood seals are used, confined water
removal and replacement is sufficient.)
– Hover without support or significant movement.
– Give, recognize and respond appropriately to common underwater communications.
– In a stationary position at a depth of approximately 20 feet (6 m), share
air in a controlled manner with another diver; be both the donor of air and the
receiver of air.
– Monitor air supply and communicate amount remaining upon request.
• Navigation Exercises. Certified assistants may accompany students during
navigational exercises or the students may be overseen by the instructor.
• Dives Beyond Those Required. No dives are to be interspersed between “required” dives.
Following satisfactory completion of all dives required for certification, dives
for the purpose of expanding the qualified diver’s experience may be overseen.
Extra dives will be charged at a rate of $80 per dive.
Advanced Scuba Diver Course
At Deep Exposure we're happy to offer the NAUI Advanced Scuba Diver course in
cozy Cozumel. We embrace NAUI's motto; "Dive Safety through Education." The
Advanced Scuba Diver class is an excellent opportunity for divers to increase
their knowledge and abilities, while gaining experience under the supervision
of a NAUI professional. Read on to learn more about this excellent program.
This course is a continuing education certification course for certified
divers. It is an enjoyable program of continued supervised experience
designed to introduce
divers to a variety of diving activities and to be taught entirely in
an open water setting. Upon successful completion of this course,
graduates are considered
competent to engage in open water diving activities without supervision,
provided the diving activities and the areas dived approximate
those of training.
course is appropriate for divers who:
- Desire additional training.
- Have moved from
one diving area to another and desire local orientation.
- Do not
have, but wish to obtain, NAUI certification.
- Desire orientation
to a variety of diving sites and conditions.
PREREQUISITES FOR ENTERING THE COURSE
- Age. Minimum is 15 years. (Junior certification for ages 12
– 14 years is allowed. (See “Policies Applying to All Courses”:
Age, Junior Certification.”)
- Dive Certification. Certification
as a scuba diver by a NAUI recognized agency is required. The instructor
is to carefully screen and evaluate
all prospective students to assure that they understand diving safety and possess
skills to participate. Curriculum and skills from other NAUI courses

greater than 80 feet (24 m), the
maximum number of students that shall accompany one instructor is four.
If one or more
assistants are used, this maximum may be increased to eight.
Academic - six hours estimated. This includes
an enrollment/orientation session, on-site discussions as necessary
for a dive’s activity
and a final session that includes an examination
based on the academic subject matter presented during
the course. The briefings for dives
in this course are
necessarily longer than those for Scuba
Diver or Master Scuba Diver because of the “academic” discussions
needed to support activities like search and recovery,
hunting and collecting,
- Open Water Dives. A minimum of six
open water dives is required. A maximum of three
dives per day shall be applied
toward course requirements. At least two dives are to be deeper than 20 feet
