  • Be certiEed in CCR Extended Range or equivalent.
  • Have logged at least 50 CCR dives, including at least 20 dives deeper than 30m, and at least ten (10) divesrequiring staged decompression.

DURATION

MATERIALS AND EQUIPMENT

  • A complete CCR Extended Range Total Diving System that:
  • Has CE-type approval (European version)
  • Is approved by SSI
  • Allowsfor manual addition of gasto the loop.
  • Has an alternate (backup) method of monitoring the loop if the primary method fails.
  • Can be conEgured so the onboard oxygen and diluent cylinders can be shut down
  • At least two (2) bailout cylinders with regulators, one (1) for bottom bailout, and one (1) for decompression with:
  • Second stage with 1-2 meter hose and SPG
  • Low-pressure inHator hose or quick-connect compatible with the unit
  • Oxygen cleaned asrequired
  • Backup OC/CCR computer for bailout in the event of a system failure
  • Two surface marker buoys(SMB), one red and one yellow, in accordance with local laws, regulations, and practices
  • Spool or reel appropriate for the planned dive depth
  • Backup mask
  • Two (2) cutting devices
  • Surface signaling device
  • Emergency spool

DEPTH LIMITATIONS

  • Open WaterTraining Dives 1 and 2 must be conducted at depthsshallower than 40 meters.
  • Open WaterTraining Dives 3 and 4 must be conducted at depthsshallower than 45 meters.
  • Open WaterTraining Dives 5 and 6 must be conducted at depth between 50 and 60 meters.
  • One (1) dive must be to a minimum of 55 metersfor certiEcation.

REQUIREMENTS FOR COMPLETION

  • Complete academic sessions and assessments as outlined in the program-speciEc instructor manual.
  • Complete the XR Water Fitness Evaluation as outlined in the General Training Standards.The snorkel swim may be replaced with a CCR surface swim while breathing from the loop.
  • Complete at least one (1) open waterskill developmentsession of at least one (1) hour.
  • Complete at least 480 minutes of in-water runtime on the applicable CCR unit.
  • Complete at least Eve (5) core open water training dives with a minimum runtime of 30 minutes each, as outlined in the program'sinstructor manual.
  • Be able to independently complete a full dive plan and bailout plan using the Extended Range Dive Planning sheet.

A. NOTES

  • All in-water training sessions must be planned within the no-decompression limits of the student’s personal dive computer, or computer-generated decompression proEles.
  • The primary planned decompression obligation (total time of all decompression stops, including any deep stops) must not exceed 30 minutesfor Open WaterTraining Dives 3 and 4, and 60 minutesfor Open WaterTraining Dives 5 through 7.
  • The maximum Equivalent Narcosis Depth for the bottom part of the dive is 35m. SSI recommends an END between 24- 30m.

At least one (1) dive must have a total run time in excess of 60 minutes.

  • Bailout cylinder volumesshould be calculated using a minimum SAC rate of 40 liters/minute.
  • The maximum ppO2 for bailout is 1.6 at the deepest planned depth of the dive.
  • Diversshould not carry an onboard diluent gas with a ppO2 higher than 1.1 bar at the bottom.
  • The maximum loop set point is 1.3 bar.

SEQUENCE

  • Open WaterTraining Dives 3 and 4 may only be conducted after completion of the XR Water Fitness Evaluation and Open WaterTraining Dives 1 and 2.
  • Open WaterTraining Dives 5 and 6 may not be conducted after the requirementsfor the academic sessions, the Enal written exam, and Open WaterTraining Dives 3 and 4 are met or exceeded.

NOTE: These core open water training dives are the absolute minimum required for certification. Students must not proceed to the next dive if they did not successfully complete the previous dive. The instructor may repeat the previous dive, or they can plan additional experience dives, before the students can proceed to the next core open water training dive.

CERTIFICATION

CCR Technical Extended Range certiEcation entitlesthe holder to dive autonomously with an equally- or more-qualiEed buddy, using trimix and specialized diving equipment and procedures, to depths of 60m, using diluent with a minimum oxygen content of 16%, and requiring unlimited staged decompression stops with a maximum of two bailout gasswitches, providing that dives are conducted in environmentssimilar to those of the diver'straining and experience.

CREDIT

CCR Technical Extended Range students may not credit divesin this program to any otherTechnical Extended Range program.This program may be conducted in conjunction with the Technical Wreck Diving program or Full Cave Diving program.

If conducted in conjunction with the Technical Wreck Diving program:

  • Open WaterTraining Dives 1-4 of the Technical Wreck Diving program may also be used to meet the requirements of Open WaterTraining Dives 1-4 of the CCR Technical Extended Range program.
  • Divers must complete all of the prerequisites,skills development and academic requirementsfor both programs.
  • The recommended maximum depth for penetration training divesis 45m, and under no circumstances may any penetration dives be conducted at depths deeper than 50m during the program.

If conducted in conjunction with the Cave Diving program:

  • Open WaterTraining Dives 5-8 of the Cave / Full Cave Diving program may be used to meet the requirements of Open WaterTraining Dives 1-4 of the CCR Technical Extended Range program.
  • Divers must complete all of the prerequisites,skills development and academic requirementsfor both programs.
  • Under no circumstances may any cave penetration dives be conducted at depths deeper than 35m on air or 60m on trimix during the program.
