During one of your first Mayan adventures with James Kidd in "Assassin's Creed 4: Black Flag", you will learn Edward Kenway's Eagle Vision can double a treasure hunting guide to help you unlock a special suit.

Locating all 16 Mayan Stelaes will unlock the Mayan Outfit in Tulum, worn by the First Civilization, which helps you deflect bullets from your enemies. This will help you a great deal in addition to your other Kenway upgrades.

Each Stelae comes in a form of a puzzle. You have to climb a Mayan sculpture and perch yourself at the top. Once you do so, shapes and lines will appear and you will have to rotate them until you solve the puzzle.

The Mayan Stelaes are hidden all over the Caribbean, so here's are the coordinate locations of all 16 of them, courtesy of IGN.
