Amassing wealth early in Assassin’s Creed Black Flag Resynced is vital for upgrading your ship – and the hidden cache at Salt Lagoon provides an ideal financial launchpad. However, players unfamiliar with the remastered edition’s subtle cartography system might struggle to locate this particular prize.
The hunt initiates with a specialized map retrieved from Abaco Island. Adventurers must decipher these geographic clues to pinpoint the exact location of the buried chest before reaping its rewards.
Geographic Coordinates and Dig Site Details

Sailors must set course for the coordinates 719,607, targeting the northwestern beach of the territory. The chest lies just south of a towering rock structure, hidden right next to the green ferns, meaning players must search closely to trigger the prompt. Digging here yields 3,000 Reales and the coveted Serpent Figurehead Design Plan for the Jackdaw.
While standard exploration rewards are generally less elusive, dedicated tracking guides remain available to help completionists uncover every single buried container across the Caribbean.

To achieve total synchronization for Salt Lagoon, players must also complete a set of regional activities scattered across the zone:
- Scale the Viewpoint located on the bowsprit of a sunken vessel near the southwestern beach
- Recover a submerged chest holding 1,000 Reales from the waters off the southern shore
- Claim a secret treasure map hidden along the northeastern edge of the beach
- Hunt the local deer populations roaming throughout the center of the island
