NACD Double/Single Cylinder Intro to Cave Diver

NACD (Double Cylinder) Intro to Cave

with Dayo Scuba, Orlando, Florida

The Double Cylinder Intro to Cave certification by NACD allows students to train in backmounted doubles (assuming they are proficient at using them), and issues a certification card stating this.

Note: The Double Cylinder Intro to Cave course is considered to be a training level only, and shall result in the issuance of a time limited temporary card. This temporary card will expire of its own force and effect one year from the date of its issuance and is not subject to renewal or extension. The student may request, prior to the expiration of the Double Cylinder Intro to Cave card, a training completion card from the instructor, and they must pay the appropriate registration fees to the NACD for issuance of an Intro to Cave diving card.

Alternatively, after training, the student may choose the regular Intro to Cave (single cylinder) certification card, which never expires.

The Double Cylinder Intro to Cave Course builds on the skills and knowledge the student acquired in their cavern course. During the Intro to Cave Course, students depart the daylight cavern zone and conduct limited, linear explorations (of the main line only) of some of the well traveled cave systems.

The Intro to Cave course is not intended to train divers for all facets of cave diving.

What it is:
The Intro to Cave course develops the minimum skills and knowledge for safe cave diving. Topics include cave diving planning, good cave diving techniques (proper line and light use), emergency procedures, problem solving, and other specialized needs of cave diving (ecosystem awareness and minimizing potential damage to the delicate cave system). An introduction to the basic guideline configurations typically found inside of popular cave-diving locations will be given. Accident analysis continues to form the basis of the training.

Agencies we teach for:
NACD

Course Cost:
$299 per person

This includes your cave manual, your dive training, a certification card, and photos (above and below water).

Other costs:
What not included is gear hire, gas fills, food, lodging, dive site fees & transportation. Dive site fees range from $10-$30, depending on site. We use Nitrox for cave diving, which is more expensive than air.

A book called Basic Cave Diving: A Blueprint For Survival by Sheck Exley is also required for all Cave students.

The more you read and prepare for your cave course, the more enjoyable it will be for you!

Gear you need to provide:
You will need to have the following gear:
* Mask (low volume)

Cave diving is a very demanding activity, and a gear intensive pursuit, your life and that of your buddy depends on the gear you use.
Choose your gear wisely!

If you have questions about gear choices call us! We have a wide selection of what is currently on the market, and have been training cave divers for many years, so we know whats good and whats not. Most local dive shops do not know what is appropriate gear for cave diving, and will sell you gear that has no place in a cave. Please call us in advance of your gear purchases.

What the course entails:

The cave course is an academic and water based course that builds on the students cavern skills. Depending on your current gear configuration and preference, you can build on your current open water gear set up, or use double tanks. Whatever you choose to wear, you must be comfortable, proficient, and have it streamlined.

How we teach it:
There are two parts, the academics and the “wet” portion.

Academics
The academics are done at home from your NACD Workbook. This guide is very well structured, informative learning tool, and excellent alternative to multiple day or evening lectures.

After you work through the manual, you will do a written test, either at home or some point before your cave course begins. You need to achieve at least 80% on your written test to pass.

When you meet with your Instructor you will do lots of land drills:
- Proficiency in the use of spools and reels while handling a light.
- Team and line placement procedures
- Zero visibility/Touch contact procedures while following a line
- Emergency procedures for lost line, lost buddy and air sharing
- Use of line markers

You will also do a full review of the academics including (but not limited too):



- Accident Analysis
- Psychological considerations of cave diving, these include stress, attitude, awareness, reaction to and building stress in self and others, stress management and philosophy.
- Guideline techniques, reel usage
- Equipment and equipment configuration
- Dive planning and gas management
- Accident prevention procedures.
- Land owner relations and cave conservation
- Cave formation and terminology
- Diving limitations including the rule of thirds & dissimilar tank sizes.


Wet Training
For the wet training, we typically do two days in the water (and at least 4 dives), and a series of vital skills such as:

- S-drill, equipment check and gear matching will begin every dive.
- Demonstrate specialized propulsion techniques without disturbing silt in the surrounding area (eg frog kick, modified flutter).
- Effective communications with both light and hand signals.
- Appropriate gas management
- Follow a line with your eyes closed, without a mask, using the touch contact method of communication.



- Running and following a safe guideline in caves



- Familiarization and exploration of caves
- Air sharing in a simulated out-of-air scenario during exit from cave.
- Lost line and lost diver procedures
- Use techniques for efficient conservation-minded propulsion techniques.
- Shut down drills



All dives will include a pre-dive briefing, bubble check, ‘s’ drill, gear matching, good dive team skills, safety stop and post dive critique.

Note: this is not a fully inclusive list, just an overview!

It should be noted that participation in this class does not guarantee certification.

Over the Intro to Cave course, divers must concentrate on developing awareness of team members, light signals, and the guideline. They must must demand good technique for the safety and efficiency of themselves and the other divers, and for preservation of the cave environment. Each student must do the required number of dives, all the skills, and demonstrate that they are comfortable with planning and executing safe and fun cave dives before they receive their certification card.

Another basic (and often overlooked) aspect of cave diving is an understanding and appreciation of the fragile nature of cave systems. You are there by choice; the caves are not, so respect their delicate ecological balance. Caves have been there long before us, and is it our responsibility as divers, to ensure their survival for future generations. Caves are important for geological and archaeological reasons, as well as for providing homes for a multitude of animals.



After successful completion of your academics and water work, you will awarded your certification as an Double Cylinder Intro to Cave Diver (which is a time limited certification, as mentioned above). This is your ticket to explore other caves, with other dive buddies. However, at Dayo Scuba we also “mentor” our students (at no extra cost), so you can gain additional experience in your favorite type of diving.


Age requirements:
You must be at least 16 years old to receive a Basic Cave certification, there is no maximum age.

Minimum # of students per class:
We need 2 or more people to make an Intro to Cave Diver class; private, one-on-one classes can be organized for a separate fee.

How many people are in each class?
Our Intro to Cave Diver classes range in size, from 1-3 students (3 is the maximum per instructor). As we travel out of town for this class, usually there are at least two instructors, and another cavern/cave class going on at the same time as yours.

Schedule/Timing for Intro to Cave Diver Course:
We train all the time, and have multiple instructors on staff, many full time, so we do weekday and weekend classes.

Call us or check out our Calendar for dates of upcoming courses.

How long does the course take?
Usually we complete the wet portion of the Intro to Cave class in 2 days, with at least four dives. Sometimes it is necessary to be in the water more than 2 days because of learning difficulties or weather issues. If necessary, you can come back, free of charge, and join in another Intro to Cave Course to finish your training. We will also train you for any extra days you may need to get you properly certified. It is our mission to make you a safe and competent diver.

Where we do our course:
We usually do our Intro to Cave training in North Florida, the caves there are very beautiful, and ideal for training (Orange Grove Springs, Peacock Springs, Little River Springs). We are very limited to cave choice around the Orlando area. We dive at least two different cave for the Intro to Cave course.

Prerequisites for Course:

* Before participating in the Intro to Cave Diver course, you will be asked to fill out a standard liability release form and a medical statement. If you answer YES to anything on the medical form we will require that you get it signed off by a physician.

* Cavern Diver certification, or equivalent.

*Advanced Open Water certification, or equivalent

* You must be Nitrox certified.
