The TDI Intro to Tech diving course
TDI Intro to Tech introduces divers to technical diving using twin sets on hogarthian style gear.
Koh Tao, Thailand
Big Blue Tech celebrates the graduation of Aida Karamesic and Chris Taylor from their TDI Intro to Tech course conducted over 2 days by TDI Instructor Ash Dunn on Koh Tao Island off the coast of Thailand.
Aida Karamesic is currently enrolled in a professional dive leader internship and Chris who is a BSAC instructor is doing his SSI Instructor Crossover before progressing on to a BSAC Advanced Nitrox Course later this week.
Ever wondered if twin set diving is for you? This course is an introduction to the skills involved in diving on a twin set, including kit configuration and emergency procedures. It will develop your practical knowledge of twin set diving and is a great way to increase your dive skills.
Initially the divers struggled with the change in buoyancy and control but improved by the second day with backwards fining and other advanced propulsion and trim techniques.
Also on the second day on the way to the dive site Green Rock the students were treated to a pod of false killer whales , which look like dolphins, that have been attracted by the change in the winds which bring food and nutrients in the currents closer to Koh Tao. Normally technical divers don’t find the same fascination with fish as other divers, it’s typically wrecks and caves that create allure but these animals were not fish so everyone was allowed to enjoy it.
There are several advantages to diving with a twin set including more available gas, extra supply for safety and stability underwater. The course is designed to familiarize divers with the skills, knowledge, planning, configuration, hazards and benefits of diving with twin scuba cylinders.
You will also learn how to calculate your surface air consumption rate in order to estimate your gas supply requirements for a given depth and time.
Once qualified you will be able to plan, organize and conduct safe dives using a twinset.
Thanks to Soren Egeberg for the pictures, he joined the course as a refresher before starting his BSAC Advanced Nitrox Course.
