Du lærer om Sidemount konfigurationer, luftberegninger, sikkerhedsøvelser, teknik og masser af praktisk erfaring i vandet.

Kurset består af: Teori og opsætning – cirka fire timer

Dykkedag 1 Open Water, to dyk. Dykkedag 2 Open Water, Et langt eller to kortere dyk

Jeg har maksimum to elever / kursus

For at tilmelde dig kurset skal du være mindst 18 år, have 25 dyk med sidemount.

Du skal have dit eget komplette udstyr, så du kan få det finjusteret under kurset.

TDI Sidemount Diver, Uddrag fra “Standards”

Introduction

This course is designed to teach certified divers how to safely utilize side- mounted primary cylinders as an alternative to the traditional back-mounted configuration.

Qualifications of Graduates

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

• Safety and decompression stops as appropriate or necessary.
• Planned dives do not exceed diver’s current certification level.

Who May Teach

This course may be taught by any active TDI Sidemount Diving Instructor.

Student Prerequisites

• Minimum age 18.
• Minimum certification; SDI Open Water Scuba Diver or the equivalent.

Course Structure and Duration

Water Execution:

• Three open water dives are required with a minimum accumulated bottom time of 90 minutes.

Course Structure:

• TDI allows instructors to structure courses according to the number of students participating and their skill level.

Duration:

• The suggested number of classroom and briefing hours is 4.
• The course must be taught over a minimum of 2 days.

Training Material

Required Material:

• SDI/TDI Sidemount Manual and Knowledge Quest or eLearning.
• SDI/TDI Sidemount Instructor Guide.

Required Equipment

The following equipment is required for each student:

• Dual cylinders, volume appropriate for planned dive, and student gas consumption.
• Two independent first and second stage regulators each with a submersible pressure gauge.
• Buoyancy compensator device (BCD) with power inflator appropriate for Sidemount configuration.
• Exposure suit adequate for diving environment.
• Mask and fins.
• Dive computer and an additional depth and timing device; backup computer recommended.

Required Subject Areas

Instructors may use any text or materials that they feel help present these topics.

The following topics must be covered during this course:

• Gas matching procedures to include dissimilar volumes.
• Gas management utilizing independent cylinders.
• Psychological considerations.
• Equipment considerations:
  • Cylinder options
  • Regulator options
  • Buoyancy compensator/harness options.
  • Proper weighting
  • Equipment configurations
• Communication:
  • Hand signals.
  • Light signals.
• Problem solving:
  • Gas-sharing.
  • Gas hemorrhages.
  • Light failure.
  • Loss of visibility.
  • Entanglement
  • Self-rescue.
• Tight spaces.
• Conservation
• Difficult water entries.
• S-Drills; specific to Sidemount.

Required Skill Performance and Graduation Requirements

The following land drills must be covered during this course:

• Land drills may be performed at the instructor’s discretion.

Pre-Dive drills:

• Use START before every dive *START is an acronym for S-drill (Out of Gas drill and Bubble Check), Team (buddy equipment checks), Air (gas matching), Route (entry/exit and planned path underwater, Tables (depth, duration, waypoints and schedule).
• Stress analysis and mitigation.

The student must perform the following in-water skills during dives:

• Demonstrate various propulsion techniques: frog kick, modified frog kick, modified flutter kick, backwards kick, helicopter turns, and hand pulling if appropriate for the environment.
• Demonstrate adequate buoyancy control; ability to hover at fixed position in water column without moving hands or Feet.
• Demonstrate adequate trim; ability to maintain proper position during the descent, bottom and ascent portion of the dive.
• Demonstrate the ability to perform the following exercises while maintaining trim and buoyancy in the water column:
  • Unclipping and attaching Sidemount cylinders.
  • Perform gas switches with and without a mask.
• Demonstrate the ability to safely manage gas in independent cylinders.
• Demonstrate conservation, awareness, and back referencing techniques.
• Deploy lift bag.
• Carry additional cylinder(s); optional.

In order to complete this course, students must:

• Perform all land drills and dive requirements safely and efficiently.
• Demonstrate mature, sound judgment concerning dive planning and execution.
• Maintain an appropriate level of awareness and respect for the environment.
• Log all dives.
