Parasu "Por" Komaradat
ExplorerWreck SpecialistCave Specialist +MineRebreather SpecialistIndependent technical, cave, mine, wreck, and CCR diving instructor trainer, and IANTD's regional manager for Thailand. Left a career in software engineering to become a full-time diving instructor, with 16+ years of experience teaching TDI, SDI, SSI, and IANTD technical courses across Thailand, Indonesia, Japan, and China. Holds 83 TDI/SDI ratings alone, spanning full cave and cave-instructor training (up to Full Cave Evaluator), mine diving, advanced trimix instructor training, and CCR instruction across multiple rebreather brands, including a Rebreather Full Cave Instructor Trainer rating. Beyond teaching, he's an active cave explorer -- part of the 'Filthy Few' team (alongside Koh Tao Divers' Mikko Paasi and fellow Thailand instructor Mika Lindström) on the ongoing Satun Cave Exploration Project, surveying a previously unmapped underwater cave system near the Malaysian border. He joined the project's second expedition into Toh Wang Cave in 2023, bringing his own compressor, booster, and CCR unit to help push the line further -- an expedition that confirmed Toh Wang as Thailand's longest known freshwater cave. In May 2026, he also played a key coordinating role in the international rescue response to a flooded mine in Xaisomboun province, Laos -- recruited early by fellow explorer Mikko Paasi for his mine-diving expertise, and named by ABC News as the coordinator organizing the rescue operation on the ground. He's also a regular speaker at regional dive industry events including TekAsia (OZTek & ADEX) and NSS-CDS, presenting on cave diving and mine diving training in Thailand.

Komaradat is an independent instructor trainer whose range includes mine diving, and IANTD's regional manager for Thailand. He left software engineering for full-time instruction and has taught TDI, SDI, SSI and IANTD for more than sixteen years. The clearest thing said about him on ScubaBoard is also the shortest: a diver looking for an IANTD technical instructor in Thailand reports finding exactly one, and names him. That is a fair description of the field. He is an active cave explorer — part of the 'Filthy Few' team with Mikko Paasi and Mika Lindström on the Satun Cave Exploration Project, surveying previously unmapped underwater cave, and called in for his mine-diving expertise during the 2026 flooded-mine response in Xaisomboun province, Laos. Mine diving instruction is genuinely rare anywhere and close to unique in the region. Few students have written about him publicly — typical of an independent instructor with no shopfront whose students are mostly other professionals — so his credentials and exploration record are the better guide; ask him for references.
