Technical diving
The underwater elite.
NDL TECH SPORT DIVER
The NDL TECH SPORT DIVER qualification allows you to dive in a technical configuration of equipment (balloon twin) without exceeding the depth limit of the previous certification level.
The aim of the course is to teach the scuba diver the basics of technical diving and prepare him for the NDL TECH-1 DIVER and NDL TECH-1 TRIMIX DIVER courses.
NDL TECH-1 DIVER
The NDL TECH-1 DIVER qualification allows staged decompression dives in a technical configuration of equipment (balloon twin, sidemount) and one staged decompression cylinder to a depth of 45 m with no decompression time limit.
Air or nitrox can be used as the bottom mixture. Any nitrox mixture up to 100% oxygen content in the mixture can be used as decompression mixtures.
NDL TECH-1 TRIMIX DIVER
The NDL TECH-1 TRIMIX DIVER qualification allows staged decompression dives in the technical configuration of the equipment (balloon twin, sidemount) and one staged decompression cylinder to a depth of 51 m with no decompression time limit.
Air, nitrox or trimix with an oxygen content of at least 21% can be used as the bottom mixture. Any nitrox mixture up to 100% oxygen content in the mixture can be used as decompression mixtures.
NDL TECH-2 DIVER
The NDL TECH-2 DIVER qualification allows staged decompression dives in a technical configuration of equipment (balloon twin, sidemount) and two staged decompression cylinders to a depth of 54 m with no decompression time limit.
Air or nitrox can be used as the bottom mixture. Any nitrox mixture up to 100% oxygen content in the mixture can be used as decompression mixtures.
NDL TECH-2 TRIMIX DIVER
The NDL TECH-2 TRIMIX DIVER qualification allows staged decompression dives in the technical configuration of the equipment (balloon twin, sidemount) and two stage decompression cylinders to a depth of 70 m with no decompression time limit.
Air, nitrox or trimix with an oxygen content of at least 18% can be used as the bottom mixture. Any nitrox mixture up to 100% oxygen content in the mixture can be used as decompression mixtures.
NDL TECH-3 TRIMIX DIVER
The NDL TECH-3 TRIMIX DIVER qualification allows staged decompression dives in the technical configuration of the equipment (balloon twin, sidemount) and three stage decompression cylinders to a depth of 100 m with no decompression time limit.
The bottom mix can be air, nitrox or trimix. Any nitrox mixture up to 100% oxygen content in the mixture can be used as decompression mixtures.
