Technical Diving

Technical Diving

Technical diving can be defined as diving that goes beyond the specified limits of recreational diving. It is non-professional diving. The diver is exposed to more risks and hazards of diving than normal diving. However, by using adequate equipment and gaining skills, the diver can equip himself to counter the dangers associated.

You may wonder, “What is the need for me to expose myself to such risks?”

If you want to tread into realms of underwater world where very few have you will need to take these risks. Technical diving will enable you to see rare wrecks. You can view exotic marine life which is not found in normal dive zones.

To start basic tech diving, you need to:

• Have PADI advanced open water diver or equivalent certification
• A minimum of 10 logged dives.
• You should be at least 18 years old.

In order to become a proficient diver, you need:

1. Equipment:

a. Twin cylinders or closed circuit re-breathers (CCR)

b. One or more additional tanks each with different gas blends.

c. Two or more independent multi-gas dive computers and regulators.

d. Back-ups of other dive gears.

e. In addition to this, the diver will need basic equipment such as

• Primary mask
• Fins
• Wing Typed BCD and Harness
• Submersible pressure gauges.
• Dry Suit, etc.

2. Planning:

Tech diving requires a lot of planning. You will need to know how much gas you need for the dive and equip yourself accordingly. You need to carry enough gas for the whole dive and carry reserve for emergencies.

Since you will be diving to great depths, you need to double-check the condition of your diving equipment.

3. Skills required:

The basic skill set required for tech diving are:

a. The divers need to complete the following checks before attempting the dive.

• Pre-dive check: Once completely dressed for a dive, each team member should check his equipment.

• Descent check: Depending on the site’s condition, each team member inspects the equipment of other team members to look for leakages and entangled equipment.

• S-Drill: This entails each team member running a gas sharing procedure with another team member.

b. Develop finning techniques and improve trim/ buoyancy control.

c. Practice valve drills.

d. In order to improve muscle memory, you need to practice removing and replacing stage/deco cylinders.

e. Practice deploying a lift bag and running a reel.

f. After every dive, time should be allocated to discussing the highs and lows of the dive.

Once you have all the essential equipment and you have taken the necessary training, you can plan your tech dive. Dive into the deep waters and discover the wonders of the underwater world!
