Exploration Diver Level III
Prerequisites
- Must be a minimum of 21 years of age
- Must be ISE Exploration Diver Level II certified
- Must have a minimum of 500 logged dives, with at least fifty (50) dives on double tanks/cylinders; twenty-five (25) of these should have utilized multiple stages
- Must be able to swim a distance of at least 35 meters on a breath hold
- Must be able to swim at least 1000 meters in less than 25 minutes without stopping.
1000 meters swimming in less than 25 min. & free dive a distance of 35 meters
or alternatively
Snorkel 800 meters (with fins) in less than 14 min. & free dive a distance of 50 meters
or alternatively
Run 1000 Meters in less than 3:30 min.
additionally
12 pushups & 8 pull-ups & 30 sit-ups in 40 sec
Purpose
The Exploration Diver Level 3 course is structured to prepare divers for the rigors of extreme exploration diving and to familiarize them with the use of different breathing and decompression mixtures while focusing on complex tasks such as Survey, Video and Scooters. The training focuses on expanding the already advanced skills learned in the ISE Exploration Diver Level II. This will include problem identification and resolution, and building the capacity for extreme exploration oriented diving. In this class, students will be trained in: a) the use of multiple Stages (min 5) and in the potential failure problems associated with them; b) the use of Trimix and Nitrox + Oxygen c) the use of Helium to minimize narcosis; and d) the applications of multiple decompression stage diving with respect to advanced decompression procedures. The class will focus on Trimix and Heliox, for dives in the 90+ meter depth range, and provides an excellent foundation for professional exploration diving in the field
Duration
The Exploration Diver Level III class is conducted in a 10-day period. It involves a minimum of 10 dives
Limits
- Student to instructor ratio is not to exceed 3:1 during any in-water training

Equipment Requirements Each student should have, and be familiar with, all of the following required equipment.
- Tanks/Cylinders: Students are required to use dual tanks/cylinders connected with a dual outlet isolator manifold, which allows for the use of two first-stages. All dives must start with a minimum of 7200 liters of gas. Also required are 3 decompression cylinders, and one Bottom Stage
- Regulators: Two first-stages, each supplying a single second-stage. One of the second-stages must be on a 7-foot/2-meter hose. One of the first-stages must supply a pressure gauge and provide inflation for a dry suit (where applicable). One first-stage regulator for shallow decompression gas and one first-stage regulator for travel/decompression gas; each one is to supply a single second-stage and a single pressure gauge.
- Backplate System: A rigid and flat platform, of metal construction with minimal padding, held to a diver by one continuous piece of nylon webbing. This webbing should be adjustable through the plate and should use a buckle to secure the system at the waist. A crotch strap attached to the lower end of this platform and looped through the waistband would prevent the system from riding up a diver's back. A knife should be secured to the waist on the left webbing tab. This webbing should support five D-rings; the first should be placed at the left hip, the second should be placed in line with a diver's right collarbone, the third should be placed in line with the diver's left collarbone, the fourth and fifth should be affixed to the crotch strap to use while scootering or towing/stowing gear. The harness below the diver's arms should have small restrictive bands to allow for the placement of reserve light powered by three in-line c-cell batteries (where necessary). The system should retain a minimalist approach with no unnecessary components.
- Buoyancy Compensation Device: A diver's buoyancy compensation device should be back-mounted and minimalist in nature. It should come free of extraneous strings, tabs, or other material. There should be no restrictive bands or "bungee" of any sort affixed to the buoyancy cell. In addition, diver lift should not exceed 80lbs. Wing size and shape should be appropriate to the cylinder size(s) employed for training.
- At least one depth-measuring device
- One timekeeping device
- Decompression tables
- Survey compass
- Mask and fins: Mask should be low volume; fins should be rigid, non-split
- At least two cutting devices
- Wet Notes
- One spool with 100 feet/30 meters of line per diver
- One primary reel per team, with a minimum of 300 feet/90 meters of line
- One primary light: A primary light should be minimalist in design; its power source should consist of a rechargeable battery pack residing in a canister powering an external light head via a light cord. Primary lights should produce the equivalent output of 18 watt HID lighting or greater.
- Two reserve lights: Reserve lights should be non-rechargeable in-line three c-cell battery lights with a minimum of protrusions and a single attachment at its rear. The light should be activated by twisting the front bezel towards the body, deactivated by turning it away from the body.
- Exposure suit appropriate for the duration of exposure.
- At least one surface marker buoy per diver.
- One Scooter
- one Video System (can be share within the team
