CCR MOD 1 Helitrox Upgrade is currently scheduled on an "On-Demand" Basis. To inquire about training and dates, please contact our training team at alex@ecdivers.com. If you have any other questions about the courses, please contact us.

This is the Helitrox Upgrade certification course for CCR MOD 1 divers wishing to utilize a closed-circuit rebreather (CCR) for mixed gas diving using a Helitrox diluent. The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills, to a maximum of 45 Metres/150 Feet, using an air/nitrox/helium diluent for formal decompression diving. Students are permitted to utilize a diluent and bailout mix with no greater than a 35% helium content (+/- 5%) and no less than a 20% oxygen content and are permitted to use up to 100% oxygen for decompression.

Before Class

Step 1.) Complete the Human Factors self-guided training via Edpuzzle. Link below.

Prior to all technical training, we require our students to review a video on Human Factors. Human Factors are a set of “Non-Technical skills” that specifically deal with environmental and organizational factors, plus human and individual characteristics, which influence behavior in team and system-driven environments in a way that can affect health and safety. We specifically focus on communication skills, leadership skills, teamwork skills, decision-making skills, and situation-awareness skills.

 

NOTE: When entering “Nicknames” in Edpuzzle, please use your full given name that the ECD staff know you by. We use these names to verify completion, and if we can’t verify you have completed the training, we will ask you to do it again.

 

HUMAN FACTORS PRESENTATION LINK:

 

We often communicate fluidly with subject matter from this program and require our Technical students to be familiar with it to successfully engage in communication with other students and us when discussing these issues.

 

Step 2.) Complete the TDI Online Training

 

The CCR MOD 1 “Helitrox” online training is Administered by TDI. Your sign-up code is:

Please head to https://www.tdisdi.com/elearni... and scroll down to the three blue boxes. Enter the code in the far right box. 

As part of the sign-up process with TDI, you can sign in to your existing TDI profile or create a new one. You now have access to the online training, which must be completed before the scheduled Zoom session.

 

Step 3.) Complete the required forms

THIS PROGRAM REQUIRES AN MD SIGN-OFF ON A MEDICAL FORM!!! NO WATERWORK CAN BE COMPLETED WITHOUT MD APPROVAL FIRST!! 

The links below contain a medical form and TDI Liability form. Please return both forms to Alex before the first Zoom session. If you do not complete these forms before the waterwork begins, you will not be able to join the class in the water and may be asked to delay training to a later date.

 

Please complete the medical form with an MD or DO signoff. Hollis requires all CCR students to have a physician sign off before training.

Step 4.) Ensure you are prepared to meet the equipment requirements

If you are a drysuit diver, that’s GREAT! All deco courses that we teach in the North Atlantic require a Drysuit. If you are not a drysuit diver, it is not a quick transition from wet to dry. You’ll need to purchase a suit and gain at least 12 - 24 dives of experience to have a chance to lock in with the suit and be prepared to have the control you’ll need to succeed in this class.

Not Sure You're Ready in Your Drysuit?

  • Can you hold position in perfect trim over a single point for 5 minutes or more without more than half a foot of depth change and without constant leg/fin movement?
  • Can you Frog Kick, Helicopter Turn, Back Kick on command in your Drysuit?
  • Do you NEVER lose control in your drysuit or ascend slightly faster or slower than you intended?
  • Can you perform tasks such as writing in wetnotes, clipping or unclipping equipment, communicating with a team member, and Deploying a DSMB without varying in depth more than half a foot?
  • Do you have video proof that you can do these things within these parameters?

If YES, you are probably ready for a Deco CCR course. If not, or you are unsure, we recommend bringing a team member with a camera to a very controlled location (we use Hathaways Pond in Barnstable), having them film you performing skills purposefully there and reviewing the video.
