Purpose

The ISE Cave Explorer Level 2 is the second in a series of three courses designed to develop full cave diving proficiency. This a very demanding course that seeks to refine the cave diving techniques of divers who have mastered the requirements of the ISE Cave Explorer Level 1.

To succeed in this course, students must be practiced in the basic aspects of cave diving and comfortable in the use of double tanks/cylinders. The ISE Cave Explorer Level 2 builds upon skills learnt previously, focusing on extending essential cave diving techniques.

These skills include: a focus on environmental awareness, dive buddy awareness, problem resolution, stress management, and advanced navigation. This course is heavily experience-based, and includes many practical, task-oriented skills that must be mastered before a student is competent to dive at this level.

Duration

This class will be conducted over a duration of 5 days, and involves at least 10 dives.

Limits

Student to instructor ratio will not exceed 3:1 in all in-water and surface sessions.
Gas consumption of maximum 1/3 of gas supply for cave penetration.
Maximum training depth of 75 meters.
Minimum of 6 meters visibility to enter the cave.
Minimum of 4800 liters of gas to enter the cave.
No scooter diving.
Certification expires after 3 years. Students have to re-qualify. (An evaluation dive)

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 4800 volume liters of gas. Divers must also have access to one stage cylinder of at least 80 cubic feet/11 liters in size. 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. One first stage 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 six line markers, of which at least three should be line arrows and three cookies.
At least one depth measuring device.
At least one time keeping device.
At least one knife as line cutting device.
At least one low volume mask.
One pair of non split, rigid fins.
One underwater notepad.
ne surface marker.
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
