Advanced Open Water Diver

There are plenty of different reasons why students sign up for the PADI Advanced Open Water course.

Some feel that they want to gain more experience from Scuba Zone's PADI instructors and undertake underwater tasks, to see different creatures or experience new adventures.

Some dive centres insist that PADI Open Water divers are supervised and this can cut down your dive time due to the buddy system, however as an PADI Advanced Open Water diver your qualification adds more credibility so you will dive with people to the same ability.

However, the largest incentive to complete the PADI Advanced Open Water course is the fact that you will be trained to dive to 30 metres as opposed to 18 metres for Open Water divers.

It is widely recognised that there are greater attractions, such as wrecks and sea-life at these depths.

Take the PADI Advanced Open Water course to open up even more exciting sights of Koh Changs national marine park and see the awesome barracuda and giant trevelly that are down there waiting for you!

Freediving
Freediving is freedom. A scuba diver relies on compressed air and equipment to enjoy the aquatic life Koh Chang has to offer where as a freediver relies on a single breath of air to explore the undersea world. Moving gracefully without wasting energy, a freediver can spend upto 7 minutes underwater and experience the ocean as all other marine life does. Free from tanks and BCD's, a freediver can sneak up on a leapard shark, or fin to the bottom for a meeting with a blue spotted ray or check out the coral.

Scuba Evolution goes DIR friendly....
We are the only tec diving outfit on Koh Chang also known as Tecevolution. We are now a DIR friendly centre and M.V.Evolution is now kitted up and ready to go for all tec divers. We stock 50% O2, 80% O2 and 100% O2 and have had a new delivery of 40 cu deco tanks. Helium is available everyday of the year for any dives you wish to use. We also have rental gear for people who don't want to carry thier own gear around the world. Apeks XTX 200's, backgas ,XTX50's, deco regs. Wings we have a selection of Halcyon and Apeks with harnesses and backplate's to complement the range. Officially Deco approved

NEW WRECK'S DISCOVERED
Scuba Koh Chang dive centre's technical department has been teaching Tec diving and taking divers on wreck trips for years. Tec Evolution offers an extensive range of technical scuba diving courses. We specialize in deep wreck diving and rebreathers.

Koh Chang has many hidden wrecks not so far from the shore and Scuba Evolution has invested time and money to find these wrecks and more importantly take you diving on them!! All wrecks found in the last month are all very interesting dives and most at 43 metres and deeper require twin set diving. We are offering DSAT Tec Deep and TDI courses so it offers everyone who is interested in getting out on the wrecks that only a handful of people will ever see the chance of a life time. If you need to hire the equipment for the courses no problem, however we offer Apeks and Halcyon at great prices for anybody that takes a course making it very affordable for most.

Diving Internships
Scuba evolution offer diving internships for people looking to change their lives forever. Scuba Evolution is looking for people as excited by as we are to help become Divemasters or PADI instructors...

Daily Dive Trips to Koh Chang National Park
As anyone who has ever taken a look beneath the waves with the aid of a diver’s mask will tell you, its coastal waters are absolutely teeming with life...

Tec Diving

Gas Blender Course
More people are diving with enriched air, Tec diving is also becoming main stream so this means the demand for enriched air fills and helium mixes is also increasing.

However, there needs to be someone qualified to administer these fills to meet this demand. This is where the PADI Gas Blender and TDI Gas Blender courses come in.

It can result in certifications: PADI Gas Blender, PADI Trimix Blender, TDI Nitrox Blender or TDI Trimix Blender.

What You'll Learn
The Gas Blender courses will train you as a qualified gas blender, allowing you to provide gas mixes to appropriately certified consumers.

You'll learn the physical properties of oxygen and helium, its associated hazards, handling requirements and what cleaning equipment is necessary. Finally, you will learn the five methods of obtaining the desired enriched air nitrox mix and the various methods used to obtain proper helium mixes.

The Learning Materials You'll Need
What are the four main types of oxygen? What is oxygen clean? What are the five methods for blending Enriched Air? How to mix helium with O2 and air to go to deep depths. These questions and more are covered in the Gas Blender manuals from DSAT and TDI.

As a gas blender you must be familiar with the physical properties of oxygen, its various forms and purities, hazards and special handling requirements. The Gas Blender Manual and CD-ROM, in conjunction with your instructor, will familiarize you with the procedures and techniques needed for gas blending.

TDI Advanced Nitrox
The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 to a depth of 40 metres during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers. The course cover topics like

Equipment requirements
Dive planning
Oxygen tracking
Blending methods

You will use the TDI Advanced Nitrox Diving manual for your course, which explains in an easy to understand practical manner the complex information that Advanced Nitrox divers need to know.

The Decompression Procedures course can be run side by side with Advanced Nitrox course for maximum benefit.

As sport divers planned decompression is not something that we do or have been taught. The TDI Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, this course is your first step beyond the normal sport diving limits. Your TDI Instructor will provide you with valuable information and skills, among the topics covered are..

( This is the DSAT chart from zero to hero of Tec diving. This will turn you into the ultimate Tec Diver once you have completed each course to Tec Trimix Diver)

- Kit set-up
- Equipment requirements
- Decompression techniques
- Decompression breathing gases
- Gas management
- Contingency planning

The TDI Decompressions Procedures course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels. Some of the materials you will be using include the TDI Divers Guide to Decompression Procedures, US Navy or Buhlmann Air Decompression Tables.

Normally if you have combined this course along with Advanced Nitrox you will be ready to move onwards and downwards to Extended Range diving course to take you below the 50m zone!!!

Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas and with a maximum depth of 55m/180 feet you won’t have to miss those dives. The Extended Range course will cover topics and skills such as

- Equipment requirements and configuration
- Decompression options
- Use of surface marker buoys
- Buddy rescue
- Narcosis checks and management

Materials for this course include the TDI Extended Range Diving Manual and the US Navy or Buhlmann Air Decompression Tables.

Advanced Trimix Diver
The TDI Advanced Trimix Diver course is the top level of training for open circuit divers wishing to dive to depths as deep as 100 m / 330 feet utilizing hypoxic levels of oxygen (below 17 percent). This course is perhaps one of the most informative and challenging and upon completion you are among some of the most elite divers. Your TDI Instructor will teach you

- Equipment management
- Multiple stage cylinder labeling and placement
- Complex decompression planning and contingency planning
- Dive team awareness and communication
- Gas monitoring and management
- Use of travel gasses

The TDI Advanced Trimix manual is one of the most up to date manuals and includes all the latest of technology and practices being used.

The ultimate in deep diving courses and as far as you can go!! If you want to spend longer on the deep wreck then your next move is Closed Curcuit Rebreathers which can give you loads of time and an accelerated Deco for everydive.

Wrecks!

- There are litreally hundreds of ship wrecks scattered across the gulf of thailand from huge tankers, to ancient pottery wrecks plus many undiscovered WWII Japanese and Allied vessels. M.V. Evolution regularly goes in search of new wrecks, here are a few of the wrecks we know about...

- HTMS Chonburi, Pak 1 (The once Vertical Wreck), Concrete wreck, Cargo Ship...

HTMS Chonburi
Depth: 45 m
Distance from Koh Chang: 3 Hours
Ship length: 70m
Width: 10m

A wreck of approx 70meters size marked by 2 large red buoys and is situated approx 200meters from the shore on the South Westerly corner of Koh Chang.
The warship(s), Sinking quite close to shore having been 'beached' in relatively shallow water in an area of sometimes strong currents and often poor 'muddy water' visibility, this large wreck must be dived at the right time to be seen at all. The ideal time is when a 'neaps' slack tide occurs around mid-day, during a prolonged period of calm flat seas. If dived at this time, visibility of 5-10m may be expected. If randomly dived during a tidal run in average weather, you might not see the wreck till you hit it (visibility of 30cm to 2m is not fun!)

PAK 1- (Previously the Vertical Wreck)
Depth: 43 m
Distance from Koh Chang: 3 Hours
Ship length: 70m
Width: 10m

http://www.thaiwreckdiver.com/vertical_wreck_pak1.htm

Concrete wreck
Depth: 55m
Distance from Koh Chang: 3 hours
Ship length: 75m
Width: 12m

NEW WRECK
Depth: 45m

Freediving

Freediving is freedom.
A scuba diver relies on compressed air and equipment to enjoy the aquatic life Koh Chang has to offer where as a freediver relies on a single breath of air to explore the undersea world. Moving gracefully without wasting energy, a freediver can spend upto 7 minutes underwater and experience the ocean as all other marine life does. Free from tanks and BCD's, a freediver can sneak up on a leapard shark, or fin to the bottom for a meeting with a blue spotted ray or check out the coral.

To get started, all you need is a basic knowledge of freediving safety, a buddy to dive with, equipment and a few tips on technique. At Scuba Koh Chang we offer hints and tips on making your free diving a safe and enjoyable experience.
The key to freediving is learning how to relax underwater. Recreational freediving runs the spectrum from snorkeling in shallow water, to making deep dives to see things beyond the range of recreational scuba diving. However, the motivations and activities for recreational freediving are much the same as for recreational scuba. The disadvantage, of course, is that your time on the bottom is limited. There are several advantages, however, to exploring the underwater world without tanks:

- Less equipment means you can get the to dive in any location so you don't need a boat.
- No bubbles which means the fish are more inquisitive
- No noise which enables the diver to hear fish and other sounds
- Movement in the water is effortless due to reduced drag
- You will visit another dimension where you can move around freely and become one with the sea and become great at spearfishing which is a fantastic sport when practised away from divesites and swimmers.

Along with the exploration of the underwater world comes the inner exploration of sensations and personal limits. Many people enjoy freediving for the feeling of sinking into the depths and floating back to the surface. Others enjoy the sensation of their heart slowing down as the diving reflex takes hold, or enjoy performance based freediving as a challenge; competing in various freediving competitions.

As normal Scuba koh chang has everything available for your freediving needs. Ranges from Picasso, Mares, Technisb and Cressi Sub are already available for masks, fins and wetsuits.We also have some special treats are coming soon. Watch this space for further information.
