Black Flag Resynced Dive Anywhere and Diving Bell: What Each Is For
The short answer
Use Dive Anywhere for shallow submerged chests and stealth approaches; use the Diving Bell for the deeper areas and rarer loot it unlocks. Resynced does not make the Diving Bell obsolete. It gives Edward a new free-dive option around the Caribbean, while preserving the Bell as the tool for depths that are too dangerous or too far down to reach unaided.
That division is useful because it stops exploration from becoming a checklist of inaccessible icons. If you see loot near an isolated playa or want to approach a shore target from underwater, Dive Anywhere may be enough. If the destination is a dedicated deep dive site, do not waste time trying to brute-force it without the Bell.

What Dive Anywhere changes
Ubisoft says Dive Anywhere lets Edward enter the water whenever and wherever he likes, even without the Diving Bell. Its two stated jobs are finding submerged chests near isolated island playas and approaching ships or shorefront targets in total stealth beneath the waves.
This is not simply a faster way to reach the same diving zones. It is a new approach tool. A player who sees a guarded shore can now consider the water as part of the route instead of only looking for a rooftop, bush, or crowd. A player sailing past a small island can check nearby shallows for a chest instead of assuming that underwater rewards are locked behind a story-gated vehicle.
The best habit is to scan the coast before landing. If a direct approach looks exposed, consider whether the water gives Edward a cleaner entry. If a playa looks otherwise empty, look beneath the surface before treating it as a wasted detour.
Why the Diving Bell still matters
The Diving Bell unlocks through the main story and grants access to varied, dangerous underwater areas containing much rarer loot. Ubisoft is explicit that Bell locations remain too deep to brave without it. That is a hard boundary, not an invitation to keep draining oxygen while hoping the game will reward stubbornness.
The Bell routes add hazards: jellyfish, sharks, fast currents in caves, and oxygen management. They are not just deeper versions of shallow free dives. Plan them as a separate activity with a reward tier worth the extra risk and navigation.
If you are early in the story, use Dive Anywhere to collect accessible loot and practice underwater movement. When the Bell arrives, revisit the deeper markers with the expectation that they are designed around longer dives, rarer rewards, and more serious environmental danger.
Staying alive underwater
Underwater exploration is not a combat arena where you can solve every threat by charging it. Watch oxygen, identify currents before committing to a cave route, and use schools of fish as stealth cover from sharks where the environment allows it. Ubisoft specifically notes that Edward can blend with fish to avoid a lurking shark’s attention.
That does not mean every shark encounter has one scripted answer. It means the game gives you a stealth option underwater just as it does on land. The same editorial rule applies: do not turn a manageable route into a fight because you assumed the first hostile thing you saw must be confronted.
Difficulty also affects diving encounters. The Activities slider changes creature damage and spawn frequency, dodge timing, incoming and outgoing damage, and interruption behavior. If you are learning the Bell’s caves, adjust Activities rather than quietly lowering unrelated Combat or Naval settings. See the difficulty settings guide for the exact scope of that choice.
A practical exploration loop
- Use the Spyglass and map to decide what resources or route you need.
- Check shallow coasts and playas with Dive Anywhere when a chest or stealth approach is plausible.
- Mark deep sites for after the Bell unlocks instead of forcing a failed attempt.
- Enter Bell dives with oxygen, currents, and escape space in mind.
- Turn rare loot into actual ship progress at a Harbormaster rather than treating it as decorative inventory.
This loop matters because loot is not the final reward. It feeds Jackdaw upgrades, which make forts, hunters, and high-level ships more manageable. The Great Inagua upgrade order explains how to spend that progress without scattering resources across low-impact purchases.
Common mistakes
Assuming free diving reaches everything. It does not; deep Bell sites remain Bell-only.
Ignoring the water as a stealth route. Dive Anywhere is valuable even when there is no chest, because it can alter your approach to a shore target.
Treating oxygen as a suggestion. A deep route should be planned around safe movement, not improvised once the meter is already low.
Confusing shallow exploration with rare-loot diving. Use each system for the job Ubisoft designed it to do.
The verdict
Dive Anywhere makes the Caribbean more permeable; the Diving Bell keeps its deepest rewards meaningful. Use the first to explore and infiltrate opportunistically, and the second to tackle designed deep-water expeditions. The two systems complement each other rather than competing for the same slot.
