It is a must for anyone intending to engage in cave diving to submit to formal training or take a refresher course prior to the dive, particularly if its been a while since his last dive. A little slip from the rules of cave diving will eventually progress to a life-threatening situation. Following the simple principles outlined below will not only mitigate the risks of cave diving, but more importantly make it a fulfilling experience-the way it should be.
Be Conscious of Your Diving Skills Level
Lack of proper training becomes the culprit to most casualties related to cave diving. There's nothing more important than getting properly trained to engage in cave dives, obtaining certification and assessing your readiness for the endeavor as well.
Keep a Good Amount of Lighting Equipment Handy
At least 3 sources of light will do. A headlight can be employed as the primary light source to give you the best vision possible and 2 other flashlights can be used as back-up.
Always Check the Gas Levels in your Diving Cylinders
The rule of the thumb requires a diver to allocate two-thirds of the air reserve for use upon exiting the cave. Likewise, make sure you are operating under the limits of your breathing equipment. Considering the visibility profile and need for longer decompression, divers are advised to carry an additional cylinder tank that is outfitted with a Y pillar valve, aside from bringing a pony bottle or an extra air source.
Get a Reliable Diving Regulator Set
Of course, nothing beats having the right scuba diving regulator set to accompany a cave diving experience. In view of the tenacity of a cave dive, any diver would need the efficiency of a high performance regulator to provide ease of breathing at whatever depth and pressure level the diver may be, even when the volume of gas available in the cylinder tank is nearing exhaustion. Now this level of regulator performance can only be achieved by a balanced diving regulator set. Using an unbalanced regulator set could imply difficult breathing when cruising depths below recreational levels.
The Aeris AT 400 Pro Regulator is a high performance regulator set outfitted with a balanced first set that comes protected by DVT or Dry Valve Technology. First stage regulators are susceptible to contamination if poorly sealed, but DVT prevents corrosive elements and flooding with the first stage to inhibit moisture and dust from contaminating the regulator. Moreover, the regulator set comes with a user adjustable second stage that allows the diver to fine tune the pressure flowing into his mouth and consequently match it with breathing. The second stage is also supported by a deflector vane (Venturi-assist) that allows for ease of breathing and prevents instances of free flow which will prove to be a risky situation during a cave dive.
Create a Reliable Reference to the Cave Exit
Using a consistent trail of markers ensures you and your group a safe and efficient exit on your way out of the cave.
