Divers should use a surface marker buoy on ascent and maintain distance from the pinnacle to avoid contact with sharp corals.

The Breman is a deliberately sunk vessel located in the Far Islands, Thailand. Resting on the seabed at depths between 16 and 25 metres, the wreck serves as an artificial reef in the open water. Divers can expect visibility ranging from 10 to 20 metres. The site is suited for advanced divers due to strong, shifting currents and the presence of overhead environments within the wreck structure.
