Salt Lagoon, similar to Abaco Island, features only few collectibles you have to retrieve, but it also includes a treasure map that will take you to another island. When you first arrive on Salt Lagoon, make sure you synchronize the viewpoint to completely reveal the island, and then focus on retrieving the buried chest following the hints provided in the guide for Abaco Island.
After you get the treasure chest, you will have to get 6 additional collectibles in order to completely gain control over Salt Lagoon, and the following guide explains how to collect them.

Assassin’s Creed IV: Black Flag Salt Lagoon Secrets Locations
The final AC4 collectible in Salt Lagoon is a treasure map. You will find the cadaver carrying the treasure map on the north-eastern beach.
The corpse is between a rock and a palm tree. Get the treasure map and you will be able to reveal the location of another buried chest. When you open the treasure map in Salt Lagoon you will see a windmill and the following coordinates: 442,118.
The coordinates lead to another location, known as New Bone, where you will find the windmill; however, you should be aware that New Bone is a restricted area and it is well protected by frigates.
Assuming that you already upgraded your ship, travel to New Bone, and you will find the windmill north-east from the viewpoint, on the cliff. While standing behind the windmill, look for a rocky area and a small palm tree. Dig in the marked location and you will reveal the buried secret chest containing 4000 R.
The video above is a walkthrough showing how to collect all items in Salt Lagoon and where to find the buried chest revealed by the treasure map you find Salt Lagoon.
