Buying guide
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.

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.
