Why Big Nomad

A Channel dive operation, run like clockwork.

We exist for one thing: getting you onto the Pas-de-Calais wrecks safely, with enough bottom time to actually enjoy them. Everything else — boats, logistics, briefings, gas blending — is built around that.

Safety first

PADI / CMAS-certified guides, redundant gas, surface support and Channel-trained skippers on every dive.

Real local knowledge

We've been working these wrecks since 2004. We know which to dive at slack, which reward Nitrox, and which to leave for trimix days.

Small groups

Max four divers per guide. No cattle-boats, no rushed surface intervals, no shared cylinders.

What divers say

Reviews from UK guests.

The most organised charter I've been on in fifteen years of cold-water diving. Krzysztof knows every shotline.
Andrew, BSAC Advanced Diver, Bristol
Four wrecks in three days, two of them I'd been waiting to dive my whole life. Faultless boat handling.
Priya, PADI Tec 50, London
Felt looked after from the ferry on. Briefings were thorough, surface support was outstanding.
Mark, Rebreather diver, Edinburgh
