Extended Range (45m)

Extended Range – The Gateway to Full Technical Diving

Step beyond the limits of recreational diving. The SSI Extended Range program is designed to train divers to independently plan and execute decompression dives to depths of up to 45 meters. Utilizing decompression gases with oxygen levels up to 100%, you will master the procedures for staged decompression stops of up to 25 minutes.

For those looking to minimize nitrogen narcosis and maximize safety, this program can be completed using Trimix.
