TDI Training

TDI Training

This week in technical diving…. It is the start of a whole month of tec diving internships in Indonesia as we welcomed both Julian and Xinwei for their TDI Advanced Nitrox and Decompression Procedures course. Julian and Xinwei are planning to complete several different trainings with Blue Label Diving instructors Hiro and Sandy, including sidemount, tec sidemount, equipment servicing workshops, and the basic level decompression diving courses.

Both Julian and Xinwei are taking these entry-level technical courses to improve their understanding about diving and make their dive plans safer. So far, they are both really impressed to find out that using more equipment underwater is not as difficult as it looks, and in fact it makes them feel like they have options to solve unexpected problems. Additionally, both students are discovering that proper dive planning can make a world of a difference – finding the right gas mixture for a certain depth, knowing exactly how much air will be used during the dive, and learning all the calculations a dive computer makes is really quite interesting for both Julian and Xinwei.

Although these students will eventually be diving to a depth of 45 meters for a bottom time of at least 20 minutes, it’s not all about going deep for the two of them. The proper dive procedures and gaining a bit of time underwater are the main goals for both Xinwei and Julian. Of course, that’s not to say they aren’t just a tad excited to see what lies hidden below 30 meters!

TDI courses in Indonesia

In the month of July both Hiro and Sandy will be guiding recreational divers through several technical dive courses. A lot of the students journey will be documented so that we can share their first-hand experiences with you. They will be arriving here as normal recreational divers, but leaving as well-rounded technical divers. Stay tuned for a video of their progress and adventures in technical diving here in Bunaken Indonesia. If you are also interested in one of the TEC Diving Internships in Indonesia please CONTACT US


Sidemount on SiladenThis week in Bunaken… Actually Blue Label Diving Indonesia wasn’t on Bunaken that much this week as we started some technical diving courses on Siladen. Using the facilities of the Siladen Resort & Spa, Blue Label Diving instructors Hiro and Sandy are teaching the Poseidon MK6 rebreather course and introducing guests staying there to sidemount diving. The reefs and fish remain the same, but the resort and island offer a change for technical divers coming to North Sulawesi for technical diving. [Read more...]

Rebreather Components – DSV & BOV

Rebreather Courses More InfoRebreather Components DSV & BOVRebreather Component 5: The DSV

The DSV stands for Diver Supply Valve and in simple terms is the mouthpiece for the loop. There will always be some sort of lever that opens the mouthpiece to the loop (on closed circuit) and shuts it again to prevent water leaking into the unit as part of all rebreather components. The DSV can also be integrated with a BOV (Bail Out Valve) which connects the mouthpiece directly to an open-circuit system. If a diver suspects problems with the quality of gas they are breathing they can switch the lever into an open-circuit mode which will connect directly to the diluent tank and allow them to breath as if they were on normal scuba. More and more rebreather models are entering the market with a BOV integrated into the DSV. [Read more...]

Rebreather Components – Scrubber & Loop

Rebreather Courses More InfoRebreather Components - Scrubber CartridgeRebreather Component 3: Scrubber Canister

The byproduct of our breathing is carbon dioxide. Carbon dioxide (CO2) is a poisonous gas that in high concentrations can cause unconsciousness and even death. In a closed breathing loop the removal of CO2 is very important. The scrubber is therefore also one of the key rebreather components in any system. The scrubber is simply a form of soda-lime that acts as a CO2 absorbent. As the exhaled breath moves up through the scrubber the CO2 binds with the soda-lime in an exothermic (heat-producing) reaction. Oxygen and other gases in the loop pass through to be rebreathed. The duration of the scrubber depends on the size of the scrubber canister, the granule size of the CO2 absorbent, temperature, and rebreather design. Improper packing of the CO2 absorbent can lead to channelling that allows CO2 to reenter the breathing loop. [Read more...]

Rebreather Component 1: Oxygen Tank

Oxygen is needed for any form of life on this planet, so it is no wonder that it ranks as one of the first rebreather components. An oxygen clean tank is located on the right side of the rebreather. The amount of pure oxygen in the tank depends on the duration of the dive, but for the most part a typical rebreather will have a 2 or 3 litre tank filled to at least 140 bar of pressure. Such a tank can supply hours worth of oxygen to a rebreather diver since consumption values are based on oxygen metabolism rather than a respiratory minute volume (RMV). The rebreather either electronically adds oxygen to the loop as the diver metabolizes it via an oxygen solenoid or the diver can manually add oxygen with a manual oxygen inject valve. [Read more...]

What are the basic rebreather components needed to create a system in which you can breathe recycled air? Understanding the basic parts of a rebreather takes the mystery out of how the system works. Here we focus on the rebreather components common to almost all modern-day rebreathers. By dissecting a rebreather you can discover just how easy a design it is.

Rebreather CCR & Sidemount Try-Outs in Indonesia

Blue Label Diving Indonesia regularly holds free rebreather and sidemount try-outs for those interested in exploring their dive limits. This is an easy way to determine the right course for you.

Check out this video from the last group who tried both sidemount and the Poseidon Discovery MKVI CCR here on Bunaken.

Divemaster Training vs. Technical Training

Technical Divemaster

Technical Divemaster

It is very common to be mislead by the term divemaster training. When you hear the term divemaster you probably get an image of a scuba guru in your mind. However, when you actually begin your divemaster training you discover that you are really being prepped to become a dive professional. There is some focus on developing personal dive skills, but the main focus of recreational divemaster training falls heavily on assisting courses, helping student divers underwater, leading dives and learning the ins and outs of a dive centre. Many divemaster training programs devote more time to these things rather than developing personal dive skills or exploring dive theory more in-depth. This is where you need to ask yourself what do you want to get out of a divemaster training?

Technical Training as an Alternative to Divemaster Training

If you are not looking to work in the dive industry but you want to develop new skill sets and explore a lot more dive theory then technical dive training is a better option for you. [Read more...]

Which Rebreather ?


Decompression dives on rebreathers in Indonesia

Decompression dives on rebreathers in Indonesia

Which Rebreather is a question that I’m asked at least once a week from potential new rebreather students looking to take the step into the silent world. A question that I’ve asked myself numerous times over the years and led to the serial owning of enough different units to make a bank manager blush with pride in the attempt to find the perfect rebreather.

Firstly, I should say that the perfect CCR does not exist, at least from the perspective of one rebreather to rule them all. What any diver should be able to find though is one which addresses their personal needs, diving and of course budget. Technical diving is an expensive pastime, but rebreather diving can potentially take this to a new level. Finding the right one for you can save thousands in a possible mistaken choice later.

Rather than be an article making comparisons between the plethora of manufacturer offerings out there, since there are more than enough polarising internet forums for that debate, here’s a few of the things that you might consider beyond the simple specifications sheet.
