We all know the drill: it’s Christmas, you need something for a diver, and you’ve already ruled out socks, bubble bath and novelty mugs shaped like sharks. Divers are easy to love but notoriously difficult to shop for — especially when half their gear needs sizing, the other half is expensive, and the rest is… well, niche.
So instead of the usual gimmicks, here’s a list of small, smart, genuinely useful stocking fillers that divers won’t just smile at — they’ll take underwater with them. Every item earns its place because it solves a real problem, replaces a bit of kit that inevitably goes missing, or makes their next dive smoother and safer.
This guide highlights proper kit — gear that saves dives, prevents drama, and earns permanent space in a BCD pocket. Every product below is an easy win for Christmas morning.
Anti-Fog: The Gift That Saves Dive
Foggy masks are responsible for more mid-dive existential crises than we care to admit. Somewhere between the descent line and the first parrotfish sighting — poof — visibility drops to windows-on-a-sauna levels. A small bottle of anti-fog solves that instantly.
Gear Aid Sea Drops™ Anti-Fog & Lens Cleaner
A classic for a reason. Strong, reliable, long-lasting and works for both diving and snorkelling masks. A stocking filler that actively prevents tantrums at the surface.
Perfect for: divers who forget to defog until they're already on the boat.
Quick-drying, easy to apply, ideal for back-to-back dives. Great option for liveaboards, dive trip holidays and anyone who likes zero fuss.
Perfect for: someone who wants a spray-and-go solution.
Powerful formula, loved by cold-water divers especially (the ones with tiny fog tolerance and big opinions).
Perfect for: the meticulous diver who expects a crystal-clear mask always.
Anti-fog may be small and inexpensive, but it’s high impact. Few gifts deliver this much underwater happiness.
Spare/Extra Comfy Mask Straps
Mask straps never break on boring dives.
They break when the water is perfect, the reef is glowing, the DM says mantas were here yesterday — and suddenly someone’s in the corner whispering WHY TODAY??
Replacing one costs little, but saves a lot of frustration.
Scubapro Velcro Neoprene Mask Strap
Soft and comfy. Works great as your regular strap or easy to replace spare.
A favourite for travellers — smooth, durable and slips on easily even when suited up.
Great for snorkellers, freedivers and holiday divers.
Mask straps are like spare fins straps, batteries and biscuits — you might not think about them until you need them, then suddenly they are everything.
Bolt Snaps: The Unsung Heroes of Every Gear Setup
If there’s one universal truth in diving, it’s this:
you can never have too many bolt snaps.
They disappear. They migrate. They get claimed by that one diver on the boat who swears “I thought it was mine.”
And when you finally need one — for your torch, spool, DSMB, backup light, wetnotes, literally anything — there is never one around.
That’s why a proper stainless-steel boltsnap isn’t just a stocking filler.
It’s a lifeline, a peace offering from the gear gods, a tiny chunk of underwater happiness.
And no — the good ones are not as cheap as they might look.
Anyone who’s ever stood at a dive shop till holding three of them knows the pain.
Which makes unwrapping one at Christmas feel like being seen. Truly seen.
Mares XR Double Ended Stainless Steel Boltsnap
Durable, sleek, corrosion-resistant. Ideal for spools, SMBs, torches — you name it.
Good for tech divers, wreck lovers and tidy-kit enthusiasts.
Strong no-nonsense hardware. Perfect for clipping a torch to a D-ring or attaching slates and tools securely.
This one wins for simplicity and reliability.
Compact Cutting Tools — Small, Mighty, Always Needed
A cutting tool isn’t just cool gear — it’s safety equipment. Fishing line, netting, monofilament, tangled fins — a small cutter can change an outcome fast.
Mares Titanium / Ceramic Line Cutter
Lightweight, rust-resistant, razor-sharp. Titanium + ceramic means you’ve got cutting power with longevity.
Perfect for safety-savvy divers.
A little more grip, a little more leverage. Good for cold-water gloves or thicker neoprene.
A favourite choice for UK divers or anyone diving with gloves.
A cutting tool stocking filler isn’t just thoughtful — it’s responsible.
You’re literally gifting them peace of mind underwater.
Slates — for the divers who love a good underwater scribble
Slates are more than communication tools. They’re underwater notebooks, sketch pads, dive plans, fish ID reminders and nudibranch celebration boards.
Aquatec Compact Slate with Pencil
Small, lightweight, fits any BCD pocket.
Great for open water divers or holiday notes.
Beaver Wrist Mounted Multi Slate
Multiple pages, wrist-mounted, quick access.
Perfect for instructors, DMs, photographers, anyone who likes to say more than hand signals allow.
If you know someone training for pro-level diving — a slate is basically required kit.
O-Rings, Grease & Fix-It Essentials
Small repairs can be the difference between diving today and crying into coffee on the dock.
A tiny maintenance kit lives in the gear bag forever — and earns gratitude again and again.
Perfect for o-rings, camera housings, torches, any rubber seal. A tiny tube that prevents big disasters.
Backup o-rings + removal tools — a lifesaver when something leaks pre-dive.
Every diver should have this. Full stop.
Zipper Lubricants & Wetsuit Shampoo
A small gift with big longevity — literally what stocking fillers are meant for.
Gear Aid Zipper Lubricant Stick
Zips hate salt, sand, neglect and low humidity. This keeps them smooth and alive.
A perfect wetsuit + drysuit longevity saver.
Gear Aid Revivex Wetsuit & Drysuit Shampoo
Because neoprene doesn’t need to smell like… post-dive reality.
Fresh kit = longer-lasting gear + happier car rides home.
None of these gifts look flashy — but they’re the kind that get used, appreciated, and re-purchased for life.
