As divers, we rely on our gear to perform flawlessly — often in remote locations, under pressure, and in environments where small failures can become big problems. That’s why an annual gear check isn’t just good practice — it’s essential.

Whether you dive every weekend or a few times a year, here’s a practical guide to what to inspect annually, what should be serviced, and when it’s time to upgrade or replace your scuba equipment.

What to check annually:

• Smooth, easy breathing from both primary and octopus
• No free-flows, leaks, or hissing sounds
• Hose condition: no cracking, bulging, stiffness, or corrosion at fittings
• Dust cap and environmental seal in good condition

Service:

• Annual servicing is recommended by most manufacturers, or sooner if:
• You dive frequently
• You’ve had exposure to sand, salt, or cold water
• The reg sat unused for long periods

When to upgrade or replace:

• Parts are no longer supported by the manufacturer
• You’re moving into colder water, technical diving, or higher gas demands
• Breathing feels noticeably harder than modern equivalents

A regulator can last decades if properly serviced — but only if parts availability remains.

What to check annually:

• Inflate fully and leave overnight — check for slow leaks
• Test oral and power inflator buttons for sticking
• Inspect dump valves and pull cords
• Look for bladder wear, stitching damage, or delamination

Service:

• Rinse and internally flush after trips
• Inflator servicing if buttons feel stiff or unreliable

When to upgrade or replace: 

• Persistent leaks or failing valves
• Poor fit or limited lift for your current diving
• You’ve changed dive styles (travel, drysuit, technical, sidemount)

Fit and comfort matter more than people think — especially on long dive days.

What to check annually:

• Battery health (replace proactively, not when it dies)
• Button responsiveness
• Screen clarity and brightness
• Compass calibration
• Transmitter O-rings and signal reliability

Firmware:

• Check for software updates — many fix bugs or improve algorithms

When to upgrade or replace:

• Battery life no longer supports dive travel
• Screen visibility is poor in low light
• You want features like air integration, better logging, or clearer displays
• The computer no longer supports your diving goals

Technology evolves fast — a 5-year-old computer can feel very dated underwater.

What to check annually:

• Neoprene compression and loss of insulation
• Zippers (smooth operation, no corrosion)
• Seals on drysuits (neck, wrists)
• Stitching and seam integrity

When to replace:

• You’re getting cold faster than before
• Zippers or seals are failing repeatedly
• The suit no longer fits your body or dive environment

Thermal comfort directly affects safety, gas consumption, and enjoyment.

Check annually:

• Fin straps or springs for cracks or corrosion
• Mask skirts for stiffness or micro-tears
• Buckles and adjustment points

Replace when:

• Rubber or silicone has hardened
• Straps show signs of tearing
• Fit or comfort has changed

Small failures can ruin an entire dive trip.

What to check:

• Battery health and charge cycles
• O-rings (clean, lubricate, replace as needed)
• Switch operation and button seals
• Charging ports and cables

Replace or upgrade when:

• Runtime is no longer sufficient
• Output no longer meets your needs
• Flooding risk increases due to aging seals

Ask yourself:

• Has my diving style changed?
• Has my environment changed?
• Has technology significantly improved safety or comfort?
• Am I compensating for gear instead of enjoying the dive?

If the answer is yes to any of the above — it may be time.

At least once a year:
✔ Service regulators
✔ Pressure-test BCDs
✔ Replace computer batteries
✔ Inspect hoses, straps, and seals
✔ Test lights and electronics
✔ Confirm fit and comfort

Your gear should support your diving — not distract you from it. Regular checks, timely servicing, and thoughtful upgrades ensure every dive starts with confidence.

If you’re unsure whether your gear needs servicing, replacement, or an upgrade, we’re always happy to help you assess it.

Safe diving,
