OPEN EVERY DAY (Including weekends and bank holidays)

Underwater Explorers is Portland's longest established dive centre based on the outskirts of Portland Marina just across from dry suit manufacturers O'Three.

We're only a couple of minutes away from Portland marina (diving hardboats) and the Sailing Academy, on the main causeway to Castletown (club boats, RIB shuttles and free slipway) and the popular shore diving site Chesil Cove.

We are a fully stocked dive shop, the largest in the region, with a modern indoor compressor unit offering air, nitrox and trimix fills throughout the year.

We have the largest rental equipment park in the area including cylinders, regulators, single or twinset wings, wet and dry suits, even twinsets and stage bottles. We also have a large stock of last minute items in case you've forgotten or need anything.

Fancy a bit of window shopping? Come indoors using Google's 360° streetview and check out our centre. Use the interactive photo below. You really don't need to buy anything :-)   But if you're down in Dorset, do drop in and say hi at least; we're a friendly bunch of divers serving divers -- with an experience in the diving industry ranging back to 1998. Whatever your agency or diving style, we are here to help.
