TUSA

TUSA has been making dive equipment since 1952, and this page holds the part of that range Oyster Diving keeps on the shelf: masks and prescription masks, dry and open-top snorkels, full-foot and open-heel fins, BCDs, regulators, gauges, knives, boots and bags, plus the TUSA Sport snorkelling line. It suits a new diver buying a first set and an experienced one replacing a single piece. We keep the spare lenses, straps and defog alongside the kit they fit.

    Building a TUSA set that works together

    Start with the mask. Fit is decided by your face, not by how much you spend, so try the seal before anything else and order any corrective lenses at the same time so they arrive together. Choose fins next: open-heel with boots if you dive in UK water, full-foot if you are snorkelling somewhere warm. Then a snorkel - dry if you want it to stay clear on a duck dive, open-top if you would rather have less to go wrong. Leave the BCD, regulator and instruments until last, once you know how often you will really be in the water, and pick up the spares that get lost first: strap sets, mask strap covers and defog.

Where TUSA fits

This is a brand page rather than a category, so you are looking across masks, snorkels, fins, BCDs, regulators, instruments, exposure kit, bags and spares from one maker. That helps when it comes to spares in particular, because TUSA straps, lenses, buckles and strap covers are cut for TUSA products.

The range splits roughly in two. The main TUSA line is scuba equipment. The TUSA Sport line covers snorkelling fins, mask and snorkel sets, water shoes and shorty wetsuits, and is aimed at snorkelling and holiday use rather than kit you would take on a hard dive.

Masks and corrective lenses

Masks are the deepest part of this collection. You will find the Paragon and Paragon S, the Freedom family in HD, CEOS, One and ELITE, Zensee and Zensee PRO, Visio PRO, Ino and Ino Pro, KLEIO II, Intega, Tina, Tri-Quest, Splendive II and the M32 IMPREX 3D HYPERDRY. There is a full-face option in the UM8001 Full Face Mask and Snorkel, and a dedicated freediving mask.

Getting the fit right

Fit is decided by the skirt, not by how much the mask costs. Hold it to your face without the strap, breathe in gently through your nose and let go. If it stays put on its own, the seal suits your face shape. Then check that tightening the strap does not lift the skirt away at your temples. A mask that seals badly will leak however good the glass is, which is why we would rather you started here than with a feature list.

If you wear a prescription

Several TUSA masks accept corrective lenses and we group those under prescription masks, including the Paragon, Freedom CEOS, Splendive II and Intega. The CEOS Prescription Mask is sold ready-made with minus or plus lenses fitted. Lenses are also sold on their own: minus and plus spherical corrections in left and right, a Reader Corrective Lens for close-up work such as reading a gauge, and a lens cut for the Paragon. Order per eye rather than per pair.

Fins, snorkels and what goes on your feet

Full-foot or open-heel

Full-foot fins such as the Solla and the RF20 Platina go straight onto a bare foot and suit warm water and snorkelling. Open-heel fins take a boot and a strap, which is what UK diving asks for: HyFlex SWITCH and SWITCH PRO, Hyflex Tri-Force, X-PERT Z-3 ZOOM, LIBERATOR X-TEN, IMPREX DUO and Travel Right. The SOLLA is also listed with a bungee strap. Boots and slippers to wear with them are on this page in hard-sole and slipper forms, along with the TUSA Sport water shoes.

Choosing a snorkel

Dry snorkels close at the top when they go under so they stay clear on a duck dive, which is the Hyperdry Elite II, Platina II Hyperdry and Sport Dry Snorkel. The Imprex II is a plain open-top design you clear with a sharp blow, and there is less to go wrong with it. Combined mask and snorkel sets sit alongside them, including Splendive, Serene, Visio Tri-Ex, Mini Kleio Dry, X-Plore and Elite.

BCDs, regulators and instruments

The scuba hardware here is a focused selection. Two BCDs, the Liberator and the BC0102B SOVERIN-Alpha. Two regulators, the RS1001 and the RS790, with the SS0001 Octopus as an alternate air source. For instruments there is a pressure gauge, a pressure and depth gauge, a combined pressure, depth and compass console and a wrist compass, plus the Element III dive computer if you would rather read your dive digitally. If you are assembling a full set rather than replacing one piece, talk to us before ordering so the regulator, BCD and gauges suit each other.

Spares, bags and the small things

The parts that get lost or wear out are listed here rather than buried elsewhere: spring strap sets, universal and Travel Right bungee straps, mask strap covers, a fabric mask strap, anti-fog film in single-lens, twin-lens and large cuts, and VIEW TEC52A anti-fog liquid. Knives run from the FK-10, FK11 and FK14 mini BC knives up to the FK910, FK920 and the titanium FK940 X-Pert II.

There is also a rescue marker and marker reel, a snorkelling vest, warm-water and tropical gloves, and bags for getting it all to the water: mesh backpacks, a deluxe drawstring bag, mesh and duffle roller bags, a dry bag and a regulator bag.

Frequently asked questions

Which TUSA brands does Oyster Diving stock?

Every product on this page comes from a single manufacturer: TUSA. That covers the main TUSA scuba range - masks, snorkels, fins, BCDs, regulators, gauges, knives, boots and bags - along with the TUSA Sport line of snorkelling fins, mask and snorkel sets, water shoes and shorty wetsuits. We do not mix other makers into this collection, so anything listed here is TUSA.

Can I get a TUSA mask with prescription lenses?

Yes. Several TUSA masks are built to take corrective lenses and we list those under prescription masks - the Paragon, Freedom CEOS, Splendive II and Intega among them. The CEOS Prescription Mask is sold ready-made with either minus or plus lenses fitted. Lenses are also available separately: minus and plus spherical corrections in left and right, a Reader Corrective Lens for close-up work, and a lens cut specifically for the Paragon. Order per eye rather than per pair, and send us your prescription if you are unsure which correction you need.

Should I choose full-foot or open-heel TUSA fins?

Full-foot fins go straight onto a bare foot and suit warm water and snorkelling - the Solla and the RF20 Platina are the full-foot options here. Open-heel fins are worn over a boot and fasten with a strap, which is what you want for diving in UK water: HyFlex SWITCH and SWITCH PRO, Hyflex Tri-Force, X-PERT Z-3 ZOOM, LIBERATOR X-TEN, IMPREX DUO and Travel Right all sit in that group, and the SOLLA is listed with a bungee strap as well. We stock TUSA dive boots and slippers to go with them, plus replacement spring and bungee strap sets.

What is the difference between TUSA's dry snorkels and open-top snorkels?

A dry snorkel has a valve at the top that shuts when the tube goes under, so it does not fill when you duck dive. The Hyperdry Elite II, Platina II Hyperdry and Sport Dry Snorkel work this way, as does the Mini Kleio Dry set. The Imprex II is a plain open-top snorkel that you clear with a sharp blow - there is less to go wrong with it, which is why plenty of scuba divers still prefer that design. Both types are on this page, and several appear in combined mask and snorkel sets.

Does TUSA make BCDs and regulators as well as masks and fins?

It does, though the scuba hardware here is a focused selection rather than a wall of options. We list the Liberator BCD and the BC0102B SOVERIN-Alpha BCD, the RS1001 and RS790 regulators, and the SS0001 Octopus as an alternate air source. For instruments there is a pressure gauge, a pressure and depth gauge, a combined pressure, depth and compass console, a wrist compass, and the Element III dive computer. If you are putting a whole set together rather than replacing one item, speak to us first so the regulator, BCD and gauges suit each other.
