Common Gear Failures and How to Avoid Them
Most divers experience a gear issue at some point, but the good news is many of these problems are preventable. A bit of awareness and routine maintenance can keep you diving safely and confidently.
1. Free-flowing regulators
A regulator stuck in free-flow mode wastes air and causes panic if you’re not ready for it. This usually stems from sand, salt buildup, or worn internal parts. Avoid it by rinsing your reg after every dive, storing it dry, and getting it serviced annually. During your pre-dive check, gently press the purge button to ensure it's functioning normally.
2. Leaky BCD inflators or dump valves
If your BCD inflates or deflates without your input, that’s a problem. Over time, salt and grime can clog dump valves or stick inflators. Fully inflate your BCD during inspections to check for slow leaks. Rinse the inside with fresh water occasionally, especially after saltwater dives.
3. Worn or broken fin straps
Snapped fin straps are a surprisingly common issue. Always inspect your straps and buckles before each dive, and carry a spare if possible. Spring straps are more durable and often easier to don, especially with gloves.
4. Mask seal leaks
A leaky mask is more than just annoying — it breaks focus and can contribute to fatigue. Check the skirt for cracks or hairline splits. Clean the mask gently with fresh water and make sure nothing (like hair or hood edges) breaks the seal.
5. Tank valve or O-ring failure
A blown O-ring right before a dive can delay or cancel your entry. Before attaching your reg, inspect the tank valve and O-ring. If it looks cracked or dry, replace it. Always carry a few spares in your save-a-dive kit — they take up almost no space and can save the day.
6. Computer or gauge malfunctions
Low battery warnings on dive computers or SPGs that stick are warning signs. Replace batteries regularly and check your devices during setup. Don’t skip the pressure gauge check when turning on your tank — it gives a quick read on system health.
7. Weight system failures
Lost weights mid-dive can make control difficult, especially during ascents. Double-check that your weights are secured and easily ditchable. Integrated BCD systems should click in firmly. If you're using a belt, make sure it's snug and positioned properly.
Preventing gear failure starts with respect for your equipment. Take the time to rinse, inspect, and maintain it — and don’t ignore small signs of wear. Most failures don’t come out of nowhere; they show up slowly. Stay ahead of them so you can enjoy every dive with confidence and control.
