CCR & OC Diving

Why Choose CCR Diving?  

 

CCR diving has gained popularity among advanced divers and technical explorers for several reasons:

1. Extended Bottom Time – Unlike OC systems, CCRs recycle exhaled gas, allowing for much longer dives with minimal gas consumption. This is especially beneficial in deep dive locations like Sipadan, where encounters with hammerhead sharks, barracudas, and turtles often happen at greater depths.
2. Silent & Stealthy Approach – With CCR, there are no noisy bubbles, making interactions with marine life more natural. This increases the chances of encountering rare species like thresher sharks and manta rays up close.
3. Optimized Gas Mixture – CCR systems allow divers to maintain an ideal oxygen partial pressure, reducing nitrogen absorption and minimizing decompression obligations.
4. Better Thermal Regulation – Since you are not exhaling into the water, CCR diving helps retain body heat, which is beneficial in long-duration dives.

Is CCR Diving Safer? 

There is no perfect rebreather system—every CCR has its risks and requires proper training. While CCR diving offers many advantages, it also introduces new complexities:

• Risk of Hypoxia & Hyperoxia – Unlike OC diving, where oxygen levels are straightforward, CCR divers must monitor and manage their gas mix carefully.
• CO₂ Buildup – A failed scrubber can lead to carbon dioxide poisoning, making it critical to perform pre-dive and in-dive checks.
• Equipment Complexity – CCR units are highly technical, requiring familiarity with electronics, gas management, and maintenance procedures.

This is why CCR divers must adapt to their unit and train consistently. Uncle Chang Resort offers CCR training and support, ensuring divers are well-prepared to handle their equipment safely.

Open-Circuit (OC) Diving in Sipadan 

For those who prefer traditional open-circuit diving, Uncle Chang Resort provides world-class OC diving experiences. With high-quality gear and expert dive guides, OC divers can explore Sipadan’s famous sites, such as Barracuda Point, Turtle Tomb, and Drop-Off Wall.

• Accessible for All Levels – OC diving is the standard entry-level diving method and is ideal for recreational divers.
• Reliable & Simple – OC systems have fewer failure points compared to CCR, making them a safer choice for divers unfamiliar with technical diving.
• Less Maintenance – Unlike CCR, OC diving does not require scrubbers, electronics, or complex gas calculations.
