ANDI Advanced Sidemount
Overhead Environments Diver – Level 3
The ANDI Advanced Sidemount (Overhead) course trains divers at Full Cave or Technical Wreck level l to use sidemount equipment configuration for extended overhead environment penetrations, including; multi-stage penetrations and techniques for very confined environment and passage through small restrictions. This course is conducted in overhead environments, with 6+ cylinders and participating students are expected to have attained a solid foundation in overhead environment competency prior to the training.
ANDI Advanced Sidemount (Overhead) Diver – Course Overview
The ANDI Advanced (Overhead) Sidemount Diver course, level 3, consists of three section:
- Theory – minimum 3 hours theory, covering different sidemount configurations and recommended uses
- Skills Evaluation and Practice – conducted in confined water/open water (depth not exceeding 10m/33ft
- Overhead Environment Dives – 6 dives, 6+ cylinders, max 2 dives per day, 180 minutes minimum diving duration
ANDI Advanced Sidemount (Overhead) Diver – Student Prerequisites
ANDI certified as Technical Wreck or Full Cave diver and Technical Scuba Diver, or equivalent
Plus the following requirements: The candidate should be able to present a log book showing current diving activity commensurate with the anticipated course objectives, competency using $+ cylinders on complex dives AND a total diving experience of NOT LESS THAN 200 dives.
Note: This is a progressive level diving course. The certification awarded indicates a high level of diving competence. In order to maintain the caliber of course graduates, additional practice dives under instructor supervision, may be required before certification will be awarded.
