There’s guiding dives and there is leading dives.

Core Responsibilities of a technical dive leader.

•Dive Management: Coordinating boat captains, managing surface support, and verifying pre-dive gas calculations (Nitrox, Trimix, or Helitrox)

•In-Water Guiding: Safely navigating complex routes inside underwater caves or deep shipwrecks while keeping the team tight and organised.

•Instructional Support: Assisting active technical instructors during intensive water skills, valve drills, and decompression-stop practices.

•Crisis Management: Acting as the primary rescue coordinator on-site, managing emergency oxygen administration, and building shared mental maps to handle unforeseen failures under pressure.

Road map to success

When individuals adopt this goal oreientated mindset, they transition from being merely “busy” to being truly effective.

Create the attitude:

How a Positive Attitude Changes Learning
* Deeper Engagement: from memorizing facts for a test to connecting concepts for long-term retention.

* Higher Resilience: When you hit a roadblock, a goal-oriented attitude prompts you to find new strategies instead of giving up.

* Proactive Resourcefulness: You actively seek out tools, mentors, and feedback to bridge the gap between your current state and your target skill level.

How to Shift Your Attitude:

* Reframe Mistakes: View errors as data points showing you where to adjust your focus, not as a reflection of your intelligence.

* Focus on the “Why”: Connect the learning material to a practical, real-world outcome you care about to sustain motivation.

* Value Progress Over Comparison: Measure your current skills against your past self, rather than comparing your pace to others.

Let’s build your roadmap.
Tell me:

* Your goal: What skill are you focusing on?
* Your reason: What is this for?
* Expectations: Where do you see yourself with your new skill?

Once I have these details, I will break your big outcome down into a step-by-step plan

Tec 50 Diver

The Tec 50 Diver course is an extended range technical diving course using two decompression cylinders and making multi-stop decompression dives.
Using the same equipment configuration as during the course, Tec 50 Divers:

•make multiple stop decompression dives to 50 metres/165 feet.

•use two decompression gases.

Tec 50 Trimix Divers can also make dives using trimix with not less than 21 percent oxygen and not more than 40 percent helium.

Divers are encouraged to complete the Tec 50 Trimix option to reduce narcosis and gas density. This course prepares the diver to
move onto deeper, more complex trimix diving, such as Tec Trimix 65 and Tec Trimix Diver courses.

Tec 45 Diver

The Tec 45 Diver course is a full technical diving course using double cylinders, sidemount
or back mount, plus a deco cylinder.

Tec 45 Diver is a prerequisite to Tec 50 Diver training.

Using the same equipment configuration they used during the course, Tec 45 Divers:

•Make single and repetitive decompression dives to a maximum depth of 45 metres/150 feet.

•Dive using either sidemount or back mount doubles manifolded with an isolator.

•use a single decompression gas, up to 100 percent oxygen, for decompression.

Tec 45 Trimix Divers can also make dives using trimix with not less than 21 percent
oxygen and not more than 35 percent helium.

Tec 40 Diver

The Tec 40 Diver course is an entry-level tec course using a single decompression gas.
It is the highest level that can be completed using single cylinder configuration. It is the bridge
between recreational and technical diving and a prerequisite for Tec 45 Diver training.
Using the same equipment configuration they used during the course, Tec 40 Divers:

•plan and make decompression dives with not more than 10 minutes of
decompression using a decompression gas, or not more than 15 minutes of
decompression using bottom gas, and not deeper than 40 metres/130 feet.

•dive with a redundant gas source, either single cylinder plus bailout cylinder,
sidemount or back mount doubles.

•use a single cylinder of decompression gas with up to 50 percent oxygen (EANx 50)
for decompression.

Tec 40 Trimix Divers can also make dives using trimix with not less than 21 percent
oxygen and not more than 35 percent helium.

Tec Basics Diver
The Tec Basics Diver course is a multi-use course that focuses on orientation to new
equipment, technical diving skills and techniques – it is an optional level. Tec Basics can be
used to prescriptively help divers learn new configurations before moving on the next Tec
Diver level.
Using the same equipment configuration as during the course, Tec Basics Divers:
dive with a redundant gas source, either single cylinder plus bailout cylinder,
sidemount or back mount doubles.
optional for divers who are at least 18 years old – dive using a deco cylinder (gas
must be breathable at all depths of the dive).

How do you and your team select the next gas from the depths?

NO TOX Gas Switch
An acronym used to remember the steps of a proper gas switch:
N – Note name and the maximum depth on the cylinder labels
O – Observe the actual depth
T – Turn open the valve. Check the cylinder pressure.
O – Orient the second stage
X – eXamine - verify with your team mate and switch gases.

Overhead wreck pe*******on!

One of my favourite topics and environments to be within, whether at 10 metres or 100 metres, wrecks are stunning engineering marvels, sadly life usually has been lost for them to be created.

We must respect a wreck for a number of reasons, be it an intentional artificial reef, or a war time sinking.

The bubbles created from scuba pose a risk to dislodging corrosion or causing path ways to be obstructed.

Taking memories and leaving items found, some wrecks are war graves.

These sites are food for underwater life.

What’s for us to learn? Plenty, entering wrecks can be illegal or just pose extra risks, so checking first.

Training is important - as you no longer may have a direct access to the surface.
Tying a line would be the smartest in any case this way you have a route to your exit.
Extra gas is usually the smartest usually a 1/6th from each tank is allowed and the metres depth you are certified is linear to the surface and how far you can go inside the wreck.
If you are 40metres diver and the wreck is at 20metres - you can only go 20metres inside.
Very important - if you were to have issue would you be covered in an emergency, do you knowingly to perform and offer assistance to a buddy.

Over head environments are really cool places to be - consider a doubles course with a wreck specialty to build confidence in yourself and team.
