Extended Range Nitrox

Extended Range Nitrox at Kron Diving is the entry point into Extended Range training, covering decompression dives to a maximum of 40 m using Nitrox mixes up to 50%. The program can be completed with a standard single-cylinder setup, which lowers the equipment barrier for divers stepping into technical territory for the first time.

Kron Diving's infrastructure supports this directly: Trimix and Nitrox fills are available on site with a booster pump, and the lead instructor Andreas is an SSI Technical International Training Director who has worked with rebreathers and Trimix for decades. The technical program here is not a bolt-on addition — it's a core part of what the center does.

Prerequisites are minimum 16 years old, 24 logged dives, and existing Enriched Air Nitrox and Deep Dive certifications. A medical certificate may be requested. Duration is 3 days.

The dive sites around Rab and the neighboring islands include walls and structures that go beyond 40 m, which provides relevant terrain for the kind of diving the course prepares students for. The step from Extended Range Nitrox toward the CCR programs that Kron Diving also offers is a well-supported path at this center.
