CCR diving courses

The rebreather opens up new possibilities for the diver and expands the boundaries of deep sea exploration.

The main advantages of closed-circuit devices are:

Significant expansion of no-decompression limits in recreational diving due to constant maintenance of the optimal breathing mixture composition for the current depth.
More effective decompression during technical diving.
Longer diving time with a significantly smaller volume of required gas, due to the closed breathing cycle.
Significantly lower gas costs.
Greater comfort during diving due to breathing warm and moist air;
Increased diving safety due to the absence of bubbles that can raise turbidity in sunken objects and silted caves.
Reduction of noise from bubbles of exhaled gas, which is important for underwater photography and video shooting.

CCR DIVER

The NDL CCR DIVER qualification allows you to perform no-decompression dives on closed-circuit breathing apparatus to a maximum depth of 40 m using air as a diluent.

CCR TECH-1 DIVER

The NDL CCR TECH-1 DIVER qualification allows you to perform decompression dives on closed-circuit breathing apparatus to a depth of up to 45 m without a decompression time limit using air as a diluent.

CCR TECH-1 TRIMIX DIVER

The NDL CCR TECH-1 TRIMIX DIVER qualification allows decompression dives on closed-circuit breathing apparatus to a depth of up to 51 m using NORMOXIC TRIMIX gases as the main breathing mixture without decompression time limits.

CCR TECH-2 TRIMIX DIVER

The NDL CCR TECH-2 TRIMIX DIVER qualification allows you to perform decompression dives on closed-circuit breathing apparatus to a depth of up to 70 m using TRIMIX gases as the main breathing mixture without any decompression time limit.

CCR TECH-3 TRIMIX DIVER

The NDL CCR TECH-3 TRIMIX DIVER qualification allows you to perform decompression dives on closed-circuit breathing apparatus to a depth of up to 100 m using TRIMIX gases as the main breathing mixture without any decompression time limit.
