The ISE Cave Explorer Level 3 is the last in a series of three courses designed to establish cave diving excellence. It teaches divers the techniques necessary to perform long range cave dives. Training emphasis is placed on advance cave diving strategies, advance gas management, efficient manipulation of multiple penetration stage cylinders, cave survey techniques, and scooter diving.

Participants must be experience cave divers who are dedicated in mastering the art of cave diving.

opencircuit backmount / sidemount or any rebreather that you are certified on.


This class will be conducted over a duration of 10 days, and involves at least 12 dives. (6 critical skills dives and 6 experience dives)


  1. Student to instructor ratio will not exceed 2:1 in all in-water and surface sessions.
  2. Gas consumption of maximum 1/3 of gas supply for cave penetration.
  3. No training dives are to exceed an equivalent narcotic depth of 30 meters, and the actual depth of 99 meters.
  4. Certification expires after 3 years. Students have to re-qualify. (An evaluation dive)

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 four stage cylinders marked appropriately. The stages should include one marked with 20 feet/6 meters, one marked with 70 feet/21 meters, one marked with 120 feet/36 meters, and one marked with 190 feet/57 meters. 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) Four 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.
  • Diver Propulsion Vehicle: The DPV should be of a design whereby the diver will be towed behind during operation. The DPV will be connected to the diver via a tow cord weaved through a 1" bolt snap. It should very importantly have the ability to be neutral buoyant, have speed adjustments and also of a clutch design. There should also be a leash on the top of the DPV.
  • At least six line markers, of which at least three should be line arrows and three rems.
  • 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 survey compass
  • One survey slate
  • One pair of non split, rigid fins.
  • One underwater notepad.
  • One 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


Tuition of min 2400 € per student + instructor's travel and diving expenses. (to be shared equally amongst all students)
