This week in Tec… Even old salty sea dogs can be taught new tricks. Dyed in the wool CMAS diver Ben from Switzerland has been coming to Bunaken for years and it looks like we may have finally persuaded him to do his decompression properly. Picture shows Ben with his “Biberon” of 50%.
I’ve now gone through the first 10 days of my divemaster course and it’s time to write a little about my experiences over the last week.
This week has primarily been about improving my skills. There are 24 specific dive skills to be mastered at demonstration-grade level, to allow me to assist a PADI instructor in Open Water training sessions. In addition to this I’ve been practicing leading groups under water and being Divemaster on a dive boat.
Yesterday Brendon and Nigel went diving with their brand new Megadolon Rebreather!!
What is a Rebreather?
A rebreather is a type of breathing set that provides a breathing gas containing oxygen and recycled exhaled gas. This recycling reduces the volume of breathing gas used, making a rebreather lighter and more compact than an open-circuit breathing set for the same duration.
There are different types and brands of rebreathers, the one that Brendon and Nigel choose is MEGALODON REBREATHER.
The Megalodon CCR Rebreather is a fine piece of diving machine sporting double heavy-duty o-ring seals on all connections, a heavy-duty aluminum stack where the electronics and Co2 absorbent canister is living in. Individualism is the motto of the day when it comes how to carry the unit ranging from Transpack soft packs to slim or full size stainless steel, aluminum or ABS backplates or even Armadillo sidemount systems. The Automatic Diluent Valve ( ADV ) is a nice safety feature addition during busy events or runaway descents. The Heads Up Display ( HUD ) is a sweet dream to dive with enabling the diver to watch the Po2 at all times, even the busiest ones.
There is a variety of configuations possible with the Megalodon CCR Rebreather depending on personal preferences. The unit is standard back mounted with front mounted cordura counterlungs. The Megalodon CCR Rebreather does not have a standard way of configuration, but can be configured to the divers needs and preferences and to suit the diving environment such as recreational diving, cave diving, technical diving or wreck diving.
SOON SOME PICTURES!!
In mid-May we welcomed back Brendon, our Course Director, for another high season in Bunaken. He is conducting a couple if IDC’s and leading our effort to discover the depths of Bunaken with Tec diving.
The Tec Diving season kicked off with 2 guests completing their PADI Tec Diver course last week. Thijs & Daan are two instructors from Lanta Divers, Koh lanta, Thailand who decided to celebrate the end of their work season with a Tec course and Tec fun-dives to explore the walls of Bunaken to 50m+.
Following the re-development of PADI’s Tec courses, we now offer three Tec courses – Tec 40, Tec 45 and Tec 50. Each of these are 3 day/4 dive courses that introduce divers to advanced diving techniques to 40m, 45m and 50m, and Bunaken is perfect for this with spectacular scenery, 40m viz and more sharks at depths!
This week Nigel started his Tec Deep Diver diving course. This is probably the first Tec course ever to be held in the area, and our aim is to explore the deeper caves & crevices of the islands at the 50-70m level. If there is colder water then there may be bigger fish! Watch this spot!!
