  1. Always Inspect Your Equipment Before Diving

Before every dive, carefully check all parts of your DEDEPU gear:

  • Ensure the oxygen tank is filled, securely fastened, and leak-free.
  • Verify the breathing valve is clean, clear, and functioning correctly.

Never use faulty or unfamiliar equipment without proper checks or guidance.

  1. Never Dive Alone

DEDEPU products are designed for reliability and safety. They meet DOT and CE certifications and pass rigorous tests under extreme conditions. You can trust our equipment to deliver consistent performance and durability during every dive.

However, safety is more than just reliable gear. Always dive with a buddy or within a group. Having a partner ensures immediate assistance during emergencies, such as:

  • Air supply issues
  • Equipment malfunctions
  • Navigational challenges or disorientation

Before entering the water, communicate clearly with your partner and perform thorough equipment checks to ensure a safe and enjoyable dive.

  1. Practice Proper Breathing Techniques

To avoid lung overexpansion injuries, always:

  • Breathe normally, and never hold your breath underwater.
  • Maintain slow, deep, and steady breaths. Rapid breathing can cause fatigue or dizziness.

Proper breathing conserves air supply and ensures a safer, more enjoyable dive.

  1. Ascend Slowly and Gradually

Rushing to the surface can be dangerous. Always:

  • Ascend slowlyto allow your body to adjust to pressure changes.
  • Pause briefly, if needed, and monitor your buoyancy.
  • Avoid rapid movements that could lead to lung injury or disorientation.

Remember, slow and steady ascents are a fundamental rule of safe diving.

  1. Be Aware of Your Environment

Stay alert to your surroundings throughout your dive. This includes:

  • Avoiding underwater obstacles such as rocks, sharp corals, or debris.
  • Respecting marine life—do not touch or disturb animals, as some may react defensively.
  • Watching for currents or changes in water conditions.

Maintain situational awareness to ensure a safe and controlled dive.

  1. Learn and Use Underwater Signals

Effective communication with your dive partner is essential. Learn and practice basic underwater hand signals:

  • OKsign: Thumb and forefinger form a circle.
  • Not OK: Hand flat, fingers waving side to side.
  • Up/Down: Thumb pointing up or down.
  • Out of Air: Hand slashing across the throat.

Review signals before diving to ensure you can communicate clearly in any situation.

  1. Monitor Your Air Supply and Dive Time

Always keep track of your oxygen levels during the dive:

  • Check your breathing time to ensure you have enough air to surface safely.
  • Do not push your limits—begin your ascent well beforethe air supply runs low.

Overestimating your remaining air can result in dangerous situations, so plan conservatively.

  1. Stay Physically and Mentally Prepared

Diving requires both energy and focus. To ensure safety:

  • Avoid diving if you are tired, unwell, or under the influence of alcohol or drugs.
  • Rest adequately before diving to remain alert and responsive.
  • Stay hydrated, but avoid heavy meals or excessive fluids immediately before the dive.

Your body and mind must be in top condition to handle underwater challenges.

  1. Respect Local Diving Rules and Conditions

Different locations may have specific rules, currents, or environmental considerations. Always:

  • Follow local diving guidelines and restrictions.
  • Avoid sensitive areas to preserve marine ecosystems.
  • Listen to local experts or guides for area-specific tips and hazards.

Diving responsibly ensures safety for you and protects the underwater environment for others.
