Scuba diving opens up a whole new world – literally. But for new divers, getting your gear sorted can sometimes feel more daunting than the dive itself. From buying the wrong kit too soon to skipping over small essentials, mistakes in equipment choices are common. The good news? Most are easily avoided. Here’s a look at the biggest gear mistakes beginners make – and how to sidestep them.
1. Buying Everything at Once
Excited new divers often rush to purchase a full kit immediately after certification. The problem? You may not yet know what truly suits your diving style. A bulky BCD, a mask that never quite seals, or fins that feel like lead – they can all quickly become regrets.
How to avoid it: Start with the basics – mask, snorkel, fins, maybe a dive computer. Rent or try different setups for your BCD and regulator until you know what feels comfortable. Build your gear bag gradually as your experience grows.
2. Skimping on the Mask
Nothing ruins a dive faster than a leaky mask. Many beginners pick a mask based on looks or price rather than fit – only to spend their dives clearing water instead of enjoying the reef. You don’t need to spend all your money on a mask, but if paying a few quid more means you get a much better fit, it’s definitely worth the investment.
How to avoid it: Fit is everything. When trying on a mask, press it gently against your face and inhale slightly through your nose – if it stays in place without the strap, you’ve got a good seal. Comfort and visibility matter far more than colour. Have a look at our masks selection here.
3. Overlooking the Importance of Fit
From wetsuits to BCDs, a poor fit can make your dive uncomfortable and even unsafe. Too tight, and you’ll struggle to move or breathe properly. Too loose, and you’ll be battling air pockets and buoyancy issues.
How to avoid it: Always try before you buy, and if ordering online, double-check sizing charts and return policies. At Mike’s Dive Store, our team is always happy to help you with fitting advice.
4. Ignoring Dive Computer Basics
New divers sometimes treat dive computers as fancy gadgets rather than essential safety tools. Skipping the manual, diving without understanding alarms, or relying on a buddy’s computer are common errors.
How to avoid it: Invest time in learning your computer – even if it’s a simple model. Know what the warnings mean, how to check no-deco limits, and how to review your log after the dive. Check out our dive computers offer here.
5. Forgetting the Small but Mighty Accessories
Spare mask strap? Defog? Clips and carabiners? Many new divers forget these “extras” – until they’re stuck on a boat with fogged-up lenses or dangling gauges.
How to avoid it: Build a small save-a-dive kit with essentials like O-rings, mask defog, cable ties, and spare straps. These inexpensive items can rescue a dive day.
6. Overweighting Themselves
New divers often add too much lead, worried about not sinking. Overweighting makes buoyancy control harder, increases air consumption, and leads to clumsy bottom-bouncing.
How to avoid it: Start with your instructor’s or dive centre’s guidance, then fine-tune with buoyancy checks at the surface. As you gain confidence, you’ll likely reduce the amount of weight you need.
7. Not Maintaining Gear Properly
Even the best kit won’t last if you neglect it. Beginners sometimes skip rinsing, store gear damp, or forget annual regulator servicing – leading to expensive repairs.
How to avoid it: Rinse thoroughly in fresh water after every dive, dry fully before storing, and follow servicing schedules. Taking care of your gear means it will take care of you.
And remember, here at Mike’s Dive Store we also offer professional servicing, so you can always bring your gear to us to keep it in top-notch condition.
