Why dive here
With 112+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and orcas - G4 offers some of Scottish East Coast & Borders's richest wreck diving.
The G4 wreck, a barge resting at 39 metres, offers a straightforward deep dive off the Scottish East Coast. While it's largely an intact hull, there are some interesting features to explore. We've found the wreck provides a decent habitat for local fish species and crabs, making it a good spot for those who enjoy poking around a solid, if not spectacular, piece of history. It’s a dive for those comfortable with depth, looking for a simple wreck encounter rather than a complex penetration.
