Koh Tao, Thailand

Today, in combination with the graduation of a TDI Decompressions Procedures course was the graduation of 12 dive master candidates who completed their Deep Diver and Nitrox Diver course with Big Blue Tech Instructors Thomas Hallstrom and Andy Cavell.

Over the 3 dives on the full day trip the students were exposed to 40m and the use of nitrox for the first time. This training is required for anyone wishing to join us on wreck diving trips coming next week.

While Andy and Thomas were in technical diving gear for safety the students, being recreational dive master interns, were in a single cylinder.

The course was combined with several different agencies which was based on the students preference.

On top of the 3 great dives it was also Martin birthday which he spent celebrating at the front of the boat from seasickness. I’m sure he’ll have a repeat performance tonight for his birthday party.

Big Blue Tech are one of the few schools who frequently conduct full day trips and this was the first one of the season after a pause from strong winds. Although the conditions at sail rock weren’t ideal it was different with soft and hard coral not seen on koh tao and an abundance of marine life not seen elsewhere.

In other news Technical Diver Nick was being lead by Technical Divemaster Ash Dunn around the site gaining more experience and continuing his fun diving with us after a day off wreck diving.


PADI Unveil New TecRec Courses

Saturday, July 11th, 2009

technical-diiver-300x199 PADI Unveil New TecRec Courses

The DSAT TecRec range was initially designed in 2000 and was soon recognised as setting a new high standard for instructional design and quality support materials. Instructors who teach the system know that a Tec Deep Diver or Tec Trimix Diver are superbly trained for technical diving. But now it’s time for a change.

Why change something that works? Well, we are not changing the best parts. The competencies at these two levels will stay the same, in other words pretty much exactly the same total set of skills and experience. However, nine years is a long time in technical diving, and the range was due for a review.

The way the review was conducted was to speak to the experts — you. We have spent a lot of time conducting forums around the world and talking to the people who teach this stuff on a day to day basis. You know what works and what doesn’t. You said you love the end product of those two courses, but that you wanted more incremental steps for divers to reach them, so that it was more practical for divers and instructors to schedule training. You also said that there should be a definite increase in a diver’s capabilities at each stage.

As no one wanted to change the overall level of information provided to the students, we have not revised the diver manuals. However, we are producing new instructor guides, knowledge reviews and exams to cover the new levels.

So here is a first look at the new TecRec range. As a general rule, each of the diver courses has four dives; in some cases the initial dives may be conducted in confined or limited open water.

Diver Levels

Tec 40

The entry point into the technical range, it provides a transition from recreational to tech. Although the use of full tech gear (doubles and wings) is preferred, it does allow modified use of recreational gear in some situations, provided the diver has two separate regulators, with one of the first stages fitted with a long hose. The intended working limit for a diver of this grade is 40 metres/130 feet with up to 10 minutes of non-accelerated decompression while breathing up to EANx50.

Tec 45

The diver now must wear the full ‘standardised’ tech rig, including wings and doubles, plus an additional deco cylinder. (Note that side mounted cylinders are an acceptable alternative to back mounted doubles throughout the TecRec range). The course will allow the diver to go to 45 metres/145 feet and make accelerated decompression dives using any mix of EANx or oxygen.

Tec 50

At the end of this course the diver will have the same set of skills and knowledge as the present Tec Deep Diver. As such it represents a high level of competency for a technical diver. Although the option exists to make the last dive of the course using trimix, it is intended as an air/nitrox rating and by the end the diver can dive to a maximum of 50 metres/165 feet and make extended, accelerated decompression dives.

Tec Trimix 65

This course opens up the advantages of trimix to the diver, and divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression, and any trimix with an oxygen content of 18% or more. They can dive to a maximum depth of 65 metres/210 feet.

Tec Trimix

This level is essentially the same as the existing course of this name. Therefore there is no numbered suffix after the course title — there are no limits are placed on how deep the diver can go after training, providing they build their experience gradually.

Instructor Levels

Tec Instructor

This is a new level of instructor in the TecRec range. The Tec Instructor will be able to teach the Tec 40 course.

Tec Deep Instructor

All existing Tec Deep Instructors keep the same credential, and will be able to offer the Tec 40, Tec 45 and Tec 50 courses.

Tec Trimix Instructor

Again, existing instructors of this level retain this credential and can offer any of the diver level courses in the range.

All these courses will be released in the next couple of months, so look for more news soon.

PADI Enriched Air and Deep Diver Specialty Course

Thursday, January 8th, 2009

Big Blue Tech has been busy again with the completion of a PADI Enriched Air and Deep Diver Specialty Course. Although this course is not specifically technical diving it is a great introduction to it and is a prerequisite for further more challenging diving.

Because of the amount it was also a pleasure to be able to take a boat to ourselves and park at South West Pinnacle for the duration of the morning for 2 back to back dives on nitrox. Later diving was completed again Chumphon pinnacle.

With another great group completed some progressed on to technical diving while others went back to their divemaster internship or fun diving on nitrox.

Below are some pictures from the event.
