Knowledge DevelopmentThe Discover Tec experience has no required knowledge development presentations or assignments.

Practical ApplicationsThe Discover Tec experience has no required practical application sessions.

Discover Tec experience DiveNote: This outline is for participants who do not wish for this experience to credit as Tec 40 Training Dive One. To qualify for credit, conduct this dive as described in the Tec 40 section, Training Dive One, Dive Today Considerations.

I. Discover Tec experience Dive StandardsA. Discover Tec is conducted in confined water or limited open water. The maximum depth is 10 metres/30 feet within no stop (no decompression) limits. The site must provide ready access to water shallow enough in which to stand.B. Ratios – 6 participants to one instructor, with 2 more participants permitted with a certified assistant to maximum of 8.C. Participants and instructor must be equipped as described in the Tec 45 Knowledge Development section with accommodation for environmental needs. A stage/deco cylinder is not required, but may be available for partici-pants who wish to try one on (with assistance). Note that if Discover Tec will be credited to the Tec 40 program, a stage deco cylinder will be required to meet the Tec 40 Training Dive One performance objectives. D. Required equipment includes but is not limited to:

1. Two cylinders of at least 12 l/70 cf each. If these are carried in back mounted configuration they should be connected with an isolator manifold. All cylinder outlets should have DIN system connections/2. Primary and secondary regulators for back mounted double manifolds, one with two metre/seven foot hose for air sharing and one with SPG. In sidemount configuration, one regulator must have the two metre/seven foot hose, and both regulators must have an SPG.3. Technical diving BCD and harness as described in the Tec 45 Knowledge Development section, or sidemount harness for sidemount4. If conducted in limited open water, the participant must have a dive com-puter, or a timer, depth gauge and tables.5. See Section Two, Standards, for general equipment requirements.Note: Although Tec 40 does not require the full technical rig, Discover Tec does. This is because Discover Tec is an experience focused on tec diving equipment.

E. Gas requirements: Air. Participants who are certified in enriched air nitrox use (any training organization) may use enriched air within the limits of their certification.

II. Predive Planning, Briefing and Preparation – suggested sequence

A. Predive briefing1. Explain that Discover Tec is an experi-ence program for trying out tec diving gear. It has no performance requirements, and it does not result in any tec diving qualifica-tions. However, you will demonstrate tec diving skills that they may try, if they want, under your supervision.

• Ifappropriate,explainthatDiscoverTecmay credit toward the Tec 40 course. In that case, there are required skills partici-pants can learn and practice. For Discover Tec to be credited to the Tec 40 course, participants must successfully complete the Tec 40 Training Dive One required skills.• Explainthattecdivingisateamactivityandthatparticipantswilldiveinteamsof two or three, and should stay together as a team.

2. Dive site overview• Depth,temperature,entry/exitpoints,areaswithwatershallowenoughinwhichto stand. • Facilities–parking,lockers,boatdry&wetareas,wheretofindemergencyequipment, etc.

3. Dive overview• Depth/timelimits.• Descent–gearadjustment,buoyancyadjustmentsandgeneralacclimation.• Tecdivingskills(optional)youwilldemonstrate,andparticipantsmaytry(listed are suggested skills – you may omit skills from this list); briefly describe each and explain that you will let participants try them one at a time with supervi-sion.

1. Gear should be set up in advance.2. Participants gear up with staff assistance. Explain what each piece of gear is and what it is for.3. Team assignments – divide participants into teams of two or three.4. Predive check – staff predive checks each participant, explaining what they are checking. Teams go through BWRAF personally as well, super-vised by staff.5. Review hand signals, emergency protocols, descent/ascent procedures and any other final details.

C. Discover Tec Experience Dive1. Entry – into water shallow enough in which to stand.

2. Descent to insensitive bottom (limited open water)•Staffgiveseachparticipant’sgearavisualcheck,includingabubblecheck.

3. Underwater gear adjustments. Give participants time to acclimate to their gear. Help with minor adjustments as necessary.4. Skill demonstrations and practice (optional). Go through the skills as briefed.Participantswhodon’twishtotryaparticularskillshouldfeelfree to skip it.

5. Free time. Participants master technical gear while remaining in teams. They may repeat skills you demonstrated, one at a time, in teams.6. Ascent – as briefed.7. Exit – as briefed.

D. Post Dive1. Performance review. After a moment to rest, get a drink, etc, but immediately while memories are fresh, have teams discuss their dives. Comment on performance and fill in added information as appropriate, but thisisanexperience,notacourse,soitisn’tnecessarytodetailoroverlycritique.2. Encourage those who are interested to continue their training in the Tec 40 course. Remind participants that Discover Tec does not qualify them to make any type of technical dive.3. If conducted in limited open water, participants log dive for your signature. If conducted in confined water, logging the experience is recom-mended, but not required.
