Cambodian Diver Found Dead Off Thailand’s Koh Larn After Trap-Recovery Dive

A Cambodian man who disappeared while diving off the coast of Koh Larn has been found dead following a two-day search operation, with Thai authorities investigating whether inadequate diving equipment contributed to the tragedy.

According to Thai media reports, 37-year-old Seng Tyno, a Cambodian national living on Koh Larn, entered the water on June 15 to recover fish traps used to support his family’s livelihood. When he failed to return, local rescue teams launched an extensive search both underwater and on the surface. His body was recovered on June 17 approximately 500 metres from the location where he was last seen. Police and rescue personnel reported that strong currents complicated search efforts.

Investigators examining the equipment recovered with the diver said he was wearing a wetsuit and carrying a scuba cylinder but lacked several pieces of equipment commonly considered standard for recreational scuba diving. Police reported that the cylinder was empty when recovered and that the diver was not carrying a buoyancy control device or a means of monitoring remaining gas supply. Authorities also noted that he was carrying significant weight, which may have hindered any attempt to make an emergency ascent.

The preliminary assessment from investigators is that the diver may have exhausted his air supply while at a depth of approximately 8 to 10 metres. However, officials have stressed that a full autopsy will be conducted before the final cause of death is determined.

While many experienced divers have safely conducted shallow dives at similar depths, the incident highlights the importance of proper equipment configuration, gas monitoring, buoyancy control and dive planning. Modern scuba training standards place significant emphasis on maintaining awareness of remaining gas supply, establishing reserve pressures and ensuring divers have the ability to achieve positive buoyancy in an emergency.

Although details remain limited, the fatality serves as another reminder that even relatively shallow dives can become life-threatening when equipment, training or emergency procedures are compromised.

The Scuba News will continue to monitor this story and provide updates if Thai authorities release further findings from the investigation or post-mortem examination.
