Nothing can ruin the excitement of a planned dive faster than arriving at the site only to discover a critical piece of equipment is malfunctioning, broken, or simply not performing as expected. A pre-season scuba gear check is essential not only for enjoyment but, more importantly, for your safety and the safety of your dive buddies. This involves getting some of your gear serviced and thoroughly inspecting the rest. In this guide, we will walk you through a pre-season gear check so you can kick off the season with peace of mind.

1. Regulator

Your regulator is arguably your most important piece of gear- it provides life support underwater. While most regulators need to be serviced every year, some have a longer service interval of two or three years (shop our favorite extended interval models below!). This includes both stages of your primary regulator as well as your backup octo or integrated octo.

Technicians perform a thorough inspection of both the first and second stages. They check for corrosion and broken external parts before taking apart the regulator. Internal parts are cleaned and examined for flaws. Filters and soft parts such as O-rings and diaphragms are replaced. Technicians will also tune the regulator and verify the integrity of the hoses. This is not something that should be attempted at home, as technicians are highly trained and have special tools and kits crucial for performing maintenance. Determine the service turnaround times at your local dive shop or repair center ahead of time to guarantee you have enough time before your first dive of the season.

If your regulator is within its service interval but you are pulling it out of winter storage, you should still verify that it is running flawlessly. Get a scuba tank and pressurize your regulator.

Listen for any leaks from the second stage. If possible, submerge the second stage in water and look for bubbles. If there is a slight leak, try increasing second stage resistance, and soaking it to loosen any debris stuck in the valve seat. If this doesn't help, bring it to a dive shop, as there may be an issue with the intermediate pressure.
Breathe from both second stages, notice any abnormalities.
Hit the purge button to confirm there is no sticking.
Take a look at the mouthpieces, scan for wear and replace if necessary.
Examine the dust cap for defects.
Evaluate hoses for any cracks, checking under hose protectors as well.
Ensure the quick disconnect on the low pressure BCD hose moves smoothly.

A great way to diagnose leaks or cracks in the system is to get a bottle of soapy water and spray it on your equipment. Bubbling indicates air leaking, and something that needs addressed. If any issues arise in your pre-season check, bring it to your local dive shop for professional advice.

2. Buoyancy Compensator

Like your regulator, you should have your BCD professionally serviced annually, or however often the manufacturer recommends. This inspection entails an examination of the inflator, dump valves, and bladder. If your BCD is not due for service when preparing for your diving season, still look over it to find any issues.

Test the inflate and deflate buttons on your inflator, and watch out for any sticking or malfunction.
Inflate your BCD until the over pressure release valve releases air.
Leave the BCD inflated for about an hour to make sure it holds. If it deflates, this could indicate a hole in the bladder, or leaking from the inflator or valves.
Release air from each dump valve.
See that all releases, clips, D-rings and weight pockets are intact and secure.

If anything is off, consult your local dive shop.

3. Tank

Local divers who own scuba tanks must get them inspected regularly. A visual inspection (VIP) by a technician must be performed annually. After taking a look at the outside of the tank for visual flaws, they open the tank to look for corrosion, pitting, and denting. The valve is scanned for any damage. Both O-rings are replaced.

Given the cylinder passes, a sticker is placed on the tank indicating the month and year. As long as the tank is within its hydrostatic testing period, you are able to fill it until the first of the month one year later. For example, if your current visual sticker is marked as May of 2025, it is due for service again on May 1st of 2026.

Every five years, tanks must be sent in for hydrostatic testing. Tanks are filled with water and pressurized to 5/3 of their working pressure to measure expansion, which indicates structural integrity. If the tank passes, the neck is stamped with the month and year. This stamp also means that it has cleared a visual inspection.

Tank upkeep is crucial for your health and safety. Dive shops will check to make sure that your tank is up-to-date on testing, so if you are not on top of it, your tank will not be filled. Many dive shops send tanks out for hydrostatic testing, so give yourself enough time to be dive-ready!

4. Computer and Gauge

The general recommendation for computer servicing is every year or two, depending on the manufacturer’s recommendation. Technicians will replace the battery and O-rings, clean any buildup, and run a pressure test. You can ensure your computer is ready for diving season by charging it up or replacing the battery before you head out for your first dive. Don’t forget to bring your charger, or backup batteries in your kit!

When you are checking your regulator before diving season, take a look at the gauge as well. While your regulator is connected to air, glance over the high pressure hose for cracks using the soapy water method. If there is air leaking near the base of the gauge, the high pressure spool may need to be swapped out (same goes for console computers). Inspect the covering of your gauge for any cracks. Confirm that the pressure gauge is working properly while hooked up to the tank. Test the compass by turning it and verifying that the needle moves correctly by comparing it to another compass, such as the one on your phone. If anything seems off, have your local dive shop take a peek.

5. Exposure Suit

Dry suits are another piece of gear that should be inspected professionally every year. This includes pressure testing, examining for leaks, cleaning zippers, checking valves, and repairing seals.

Wetsuits should be thoroughly looked over, searching for any tears, holes, or other damage. Neoprene cement comes in handy for small flaws. Verify that all zippers are working smoothly, and lubricate if necessary.

6. Weights and Belts

If you use a weight belt, examine it for any tears, and ensure that the buckle is intact and fastens securely. As for soft weights, inspect for any holes that may be releasing lead beads. Assure you have the proper amount of weight, and your weight system should be ready to go!

7. Snorkeling Gear

Unlike scuba gear, snorkeling gear maintenance is simple:

Take a look at your mask, feeling for any tears in the skirt or strap.
Ensure that your snorkel clip is intact, and that the mouthpiece is not ripped.
Check the integrity of your fin straps.

These parts are straightforward to replace on your own if needed.

8. Save-a-Dive Kit

Finally, you’ll want to re-stock your Save-a-Dive Kit! Confirm that you have:

Backup O-rings
Mask straps
Fin straps
Silicone lube
Tools
Mouthpieces
Zip-ties

These are items that come in handy throughout diving season, when your gear needs small fixes. Having a great backup kit can also make you a favorable dive buddy!

Pre-Diving Season Checklist

Regulators and Hoses: Check for any signs of cracking, fraying, or degradation on hoses. Have your regulator set serviced annually, or as recommended by the manufacturer, to ensure proper air delivery and function.

Buoyancy Control Device (BCD): Inspect the BCD for any leaks, tears, or signs of wear on the fabric or seams. Verify that all inflator and dump valves are operating smoothly and holding air pressure. Ensure the tank band and buckles are secure and functioning correctly.

Cylinders (Tanks): Confirm that your tank has a current Visual Inspection (VIP) sticker (done annually) and a valid Hydrostatic Test stamp (every five years). Do not dive with an expired tank inspection.

Exposure Protection: Check wetsuits or dry suits for tears, leaks, or broken zippers. Ensure boots, gloves, and hoods are still in good condition.

Mask, Fins, Snorkel: Inspect the mask skirt for cracks or discoloration, and ensure the strap is secure. Check fins for cracks or stress marks.

Computers: Charge it up or replace the battery! Have it serviced every year or two for pressure testing.

For any gear that requires professional servicing, especially regulators, BCDs, or tanks, plan ahead of time. Service centers often experience a rush as the diving season begins, so bringing your equipment in well in advance will prevent frustrating delays. Proper maintenance not only extends the life of your expensive equipment but also ensures peak performance and, most importantly, your safety underwater.

If your gear is getting old and questionable, don't be afraid to replace it. At Santa Barbara Aquatics, you can trade in your old gear for a discount on select new items.
