Exploration Diver Level II

Prerequisites

1. Must be at least a minimum 20 years of age.
2. Must be ISE Exploration Diver Level 1 qualified.
3. Must have a minimum of 200 logged dives, with at least 50 dives on double cylinders, 25 dives of these must have utilized a single decompression cylinder.
4. Must be able to perform the following:

600 meters swimming in less than 15 min. & free dive a distance of 20 meters
or alternatively
Snorkel 800 meters (with fins) in less than 16 min. & free dive a distance of 30 meters
or alternatively
Run 1000 Meters in less than 4 min.
additionally
10 pushups & 6 pull-ups & 30 sit-ups in 40 sec

Purpose

The ISE Exploration Diver Level 2 course is structured to prepare divers for the rigors of exploration diving, and to familiarize them with the use of different breathing and decompression mixtures. The training focuses on expanding the basic skills learnt in the ISE Exploration Diver Level I, and is designed to build the necessary and essential skills required for safe and successful extended exploration diving.

This will include problem identification and resolution, and also building the capacity for progressively more challenging diving. In this class, students will be trained in:

1. the use of multiple stages and the potential failure problems associated with them.
2. the use of Trimix, Nitrox and Oxygen.
3. the use of Helium to minimize narcosis; and
4. the applications of multiple decompression stage diving with respect to decompression procedures.

The class will focus on Trimix, for dives in the 80 meter depth range, and provides an excellent foundation on which divers can build their diving experience and prepare for ISE´s further program.

Duration

This class will be conducted over a duration of 6 days, and involves at least 10 dives.

Limits

1. Student to instructor ratio will not exceed 3:1 in all in-water and surface sessions.
2. Trimix 18/45 and 15/60 with Nitrox 50 and Oxygen
3. Maximum training depth of 75 meters.
4. No overhead environment. (i.e caves)
5. Certification expires after 3 years. Students have to re-qualify. (An evaluation dive)

Price

Tuition of 1200 € per student + instructor's travel and diving expenses. (to be shared equally amongst all students)

Equipment Recommendations

All students must have the following equipment for the course. Please email the instructor should you have further enquiries.

• Tank/s: Students are required to use double tanks. Double tanks setup requires a dual outlet isolator manifold, which allows for the use of two first-stages. All dives must start with a minimum of 2250 volume liters of gas. Divers must also have access to three cylinders marked appropriately. One appropriate drysuit cylinder.
• Regulators: For double tank setup, one first stage must provide a second stage on a 2 meter hose and inflation for buoyancy compensator. The other must provide a second stage on a hose not exceeding 60 cm, attached with a shock cord on the mouth piece. It must also provide a pressure gauge on a hose not exceeding 60 cm, and inflation for dry suit. (where applicable) Three first stages must provide a second stage on a 100 cm hose and also a pressure gauge. One drysuit inflation system.
• Backplate: A rigid and flat platform, of metal construction held to the diver by one continuous piece of nylon webbing. This webbing should be adjustable through the plate with triglides to hold positions, and a buckle to secure the system at the waist. A crotch strap attached to the lower end of the plate and has a loop to pass the waist band through to secure the system. A knife sheath should be attached at the waist and will be adjusted beside the crotch strap when ready. This webbing should support five D-rings; 1 on the left, and 1 on right shoulder strap, both approximately the collar bone level. 2 on the crotch strap with one at the front and one at the buttocks. The shoulder straps should have small rubber bands to hold the back-up lights. The system should have no unnecessary components.
• Buoyancy Compensator Device: The buoyancy compensator device should be back-mounted and streamlined with only one inflator. There should be no bungee cords of any sort on the buoyancy cell. The lift should not exceed 25 kg for doubles. Wing size and shape should be appropriate to the cylinders used during training.
• Lighting Systems: The primary light that should be of a canister with light cord connecting to the light head design. The battery should be inside the canister and a slot to position it on the right hip location on the waist strap. The light head should have a goodman handle with a bolt snap attached, and a loop at the bottom of the light head. The primary light should be at least a 10 watts HID or equivalent.
  At least two back-up lights that are of a twist on and off bezel design. It should be an in-line battery design that do not overdrive the bulb. There should be no on/off switch for the back-up lights. The back-up lights will have bolt snaps attached to the back of it for stowage to the system.
• At least one depth measuring device.
• At least one knife as line cutting device.
• At least one low volume mask.
• At least one surface marker per diver.
• One survey compass.
• One time keeping device.
• One pair of non split, rigid fins.
• One underwater notepad.
• One spool of at least 30 meters of line per diver.
• One primary reel of at least 90 meters of line per diver.
• One drysuit that is appropriate for the training environment and water temperature.
• Decompression tables.
