  2. Must be qualified in IANTD Deep Diver or RCCR Deep Diver or equivalent.
  3. Proof of a minimum of 50 logged dives.

Class Content and Equipment

  1. Classroom academics
  2. Build class
  3. Confined water
  4. Minimum 7 open water dives
  5. Maximum 15 minutes decompression
  6. SMB and reel

Skills included but not limited to:

  1. Open circuit bail out drills
  2. Hypoxia, hyperoxia, hypercapnia and “boom” drills.
  3. Valve shut offs.
  4. Remove and replace rebreather under water (ditch and don).
  5. No mask swim.
  6. Remove and replace bailout bottles while swimming.

This list is by no means all inclusive and is intended to give the student a feel for what is done in a typical class. I do not teach to a minimum standard so expect to do more than the minimum number of dives and minutes required. I tailor classes around the students needs and abilities so he or she will reap the maximum benefit. When we finish I want you to be both comfortable and confident on your new rebreather.

Cave

Cave diving is a very serious but very rewarding endeavor. I do not subscribe to the modular approach for training. You are either a Cave Diver or you are not and I do not believe in giving someone access to an environment they are not fully trained for. That said, I expect my students to demonstrate not only the skills but the attitude necessary to be a successful and safe Full Cave Diver. To accomplish this you must have a commitment to constantly work on perfecting your skills and maintaining them. Cave diving is an attitude, a passion and a mindset.

Prerequisites

Open Circuit:

  1. Must have proof of 100 dives or sufficient experience doing technical dives to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.

Rebreather:

  1. Must have proof of 100 rebreather dives.
  2. OC Cave Diver to Rebreather Cave Diver Crossover: Must be qualified as Rebreather Diver on the unit to be used and have 25 rebreather dives with 50 hours of dive time on the Rebreather.

Crossover From Open Circuit Cave to CCR Cave:

1. A minimum of 200 minutes of cave bottom time;
2. Two (2) rebreather cave dives.
► NOTE: This Program must include a confined water session.
► NOTE: All CCR cave specific skills must be completed.
3. (RB) Each team must carry stages or adequate bailout gas or bailout rebreathers to get a minimum of 1½ divers to the surface.
4. (RB) Bailout cylinder PO2 may not exceed 1.6 at the MOD and may not have an END greater than
120 fsw (36 msw)

Class Content and Equipment

  1. Classroom academics.
  2. Land line drills
  3. Minimum 10 dives for CCR and 12 dives for Open Circuit.
  4. Minimum 500 minutes in water time for Open circuit and 600 for CCR.
  5. 1 staged deco bottle for Open Circuit. 1 bailout bottle required for CCR plus appropriate staged decompression gas.
  6. Minimum of 3 Reels. A 400 foot primary, a 140 foot Safety and a 50 foot jump reel. Spools are acceptable.
  7. Line Arrows and Cookies or other non directional marker.

Skills and Topics included but not limited to:

  1. Proper use of reels.
  2. Interpreting line markers.
  3. Running a primary reel.

Instruction

I take instruction very seriously. Whatever knowledge I impart to a student will stay with him or her for a very long time so it is important that courses are of the highest quality. My motivation is that diving is my passion and I want to share what I have learned over the years with others.

My rebreathers of choice are the Megalodon and SF2 CCRs.  I teach and recommend both depending on your needs.  Both are simple designs and less prone to problems.  Both can be de-watered easily and have an ADV (Automatic Diluent Valve) that can be shut off.  Both have an OPV (Over Pressure Valves) well suited to their task neither requiring extreme tactics to control loop volume when bailing out.  If you want to learn to dive a Megalodon  or an SF2  from someone with real world experience give me a call.

I also teach open and closed circuit Trimix, Cave, DPV Cave and Technical Wreck. My courses are comprehensive and challenging. You will get what is in the book and a lot that is not. My goal is to give the student the tools necessary to evolve into a world class diver and one day be able to participate in dives at any level anywhere.  Of course these tools will serve them well no matter what their aspirations might be.
