SDI Computer Diver Course

In

The SDI Computer Diver Course is designed to expand a diver’s knowledge in the use of their personal dive computer (PDC) and is primarily intended for divers who are certified with agencies using traditional dive tables for planning, rather than PDC’s throughout training.

Who this course is for:

The certified diver looking for more information to maximize their use of a computer for scuba diving

Course prerequisites

SDI Open Water Scuba Diver, SDI Junior Open Water Diver, or equivalent

Minimum age 18, 10 with parental consen

What you can expect to learn : 

The SDI Computer Diver course takes an in-depth look at all of the following and more:

• Computers vs. tables
  
• History of tables
  
• Computers advantages
  
• Different decompression models
  
• Decompression sickness
• Cause
• Signs and symptoms
• Treatment
• First aid
• Prevention

• Air integrated
  
• Non-air integrated
  
• Features

• Decompression information in permanent memory
  
• Pressure transducer reads ambient pressure
  
• Internal clock records lapsed dive or surface time, updates frequently, usually every 3 seconds
  
• Information is calculated in the computer microprocessor during each update
  
• Information is displayed on screen
• User is responsible for interpreting information
• Use of dive computers
• Always read manual first
• Start-up procedures
• Operating instructions
• Ascent rates
• Other information

Dive time:

Elapsed time from beginning of descent until final surfacing at end of dive

Time remaining:

Available time, according to computer program, that diver may remain at current depth without incurring mandatory decompression; increases as depth decreases

Planning Multi-Level Repetitive Dives

Dive planning mode

First dive or repetitive dive

Only One Diver per Computer

Very unsafe practice for two divers to attempt to monitor dive profiles with one computer

Emergency Procedures

Decompression

Omitted decompression

Ascent rates

Computers varying ascent rates determined by the manufacture

Computer failure

Some of the required skills you will have to demonstrate include:

Diver must prepare a suitable multi-level profile for training dives

The diver is to monitor depth, buoyancy control, and air supply during the dives. For example, if the dive is projected for 21 metres/70 feet maximum depth; the diver must then monitor his depth and not exceed the planned maximum depth

Execute a safety stop must be included at the end of each dive

After completing the 2 dives the divers must download their computers if they have the capability

Instructors must review this information with the student

What’s in it for you?

Upon successful completion of this course, graduates may engage in diving activities without direct supervision of the SDI Instructor* so long as the following limits are adhered to:

The diving activities approximate those of training

The areas of activities approximate those of training

Environmental conditions approximate those of training

*Note: Junior divers (ages 10-14) must participate in diving activities with a parent, guardian, or dive professional.

Also, the SDI Computer Diver certification counts towards a single specialty rating to achieve the SDI Advanced Diver Development Program.

SDI Computer Diver minimum requirements:

Satisfactorily complete the SDI Deep and Dive Computer Knowledge Quests with a passing score of 80%, followed by 100% remediation by the Instructor

Complete all open water requirements efficiently

Demonstrate mature and sound judgment concerning dive planning and execution
