Another factor which differentiates the two types of diving is dive time. Hypothetically speaking, if a recreational scuba diver on a single tank was to dive to 50 meters it is unlikely they would have enough air left in their tank to make the required decompression stops on the way to the surface.
Blue Ocean Dive Resort and Aliwal Shoal and surroundings cater to all divers and that includes Tec divers.
What is Tec Diving?
Going places other divers can’t go, seeing things no other divers can see and enjoying depths and longer bottom times than most other divers.
Tec Diving allows you to increase your limits in bottom time and depth. Going deeper than a normal recreational scuba diver or stay down for longer on shallower reefs and wrecks.
Why do people Tec Dive?
Exploration: Tec divers get to go places that very few people have been or in some cases never been before. World War Ship, Plane wrecks and even some “lost cities” are most of the time out of recreational diving limits.
Diversity: While recreational divers get to see most of the same marine life that technical divers get to see, some marine species prefer deeper waters, such as the coelacanth and pelagic sharks.
Destinations: Some dive destinations are emphasised by tech diving, too beautiful for the recreational limits of around 50 minutes bottom time on Nitrox, you simply want to stay down longer or visit deeper sections more. The Red Sea has a few of these types of sites such as the Blue Hole and Thomas’ Canyon. Chuuk Lagoon has amazing ship wrecks where the Japanese Fleet was sunk in World War ii.
How do you become a Tec Diver?
Doing our Tec 40 course is the start of exploration that you’ve never even imagined. Learning the basics of Technical Diving and having fun by visiting sites deeper than you’ve been before. This is the transition course between a recreational scuba diver and a technical scuba diver. You will learn, technical diving’s risks and responsibility, technical diving equipment, proper rigging and set-up, gas planning, oxygen limits and decompression planning, team diving techniques and emergency planning. The course consists of 3 academic sections and 3 practical sessions and 4 training dives.
Pre-requisites are: Minimum age of 18 years old. A medical statement signed by a physician within 12 months.Advanced Open Water certification Nitrox Qualification with a minimum of 10 dives on Nitrox to 18m or deeper. Deep Dive Speciality or proof of 10 logged dives to 30m.Proof of 30 or more dives logged. If you’re not sure you can simply do a Discover Tec Diving which entails 1 pool session and 1 dive.
How Deep Can Technical Divers go?
Tec divers generally do go way deeper than recreational Scuba Divers. While the Deep Diver Speciality allows you to go to 40m under recreational limits your bottom time is limited and before you’ve got comfortable and settled it’s time to ascend. In tec diving, these bottom time limits are extended through different gas mixes at different depths which lower the risks of narcosis, oxygen toxicity and DCS. The deepest recorded dive, breaking the world record is 332.35m by 41 year old (at the time), Egyptian, Ahmed Gabr.
