Technical Extended Range


The intent of the SSI Technical Extended Range program is to provide divers with the training necessary to independently plan and conduct two-gas switch, multiple-stop decompression dives to depths of up to 60 meters / 200 feet, using specialized diving equipment and procedures with an equally-qualified dive buddy. You will earn the SSI Technical Extended Range (with or without Trimix) certification after completing this program.
