For the first time in Asia, rEvo Rebreather training is now available in Singapore and across the Asia with Mr. Davy Koh – the 1st rEvo Rebreather Diver/Instructor in Asia.

Davy Dive Explorers is one of the earliest TDI Instructors in this region, and has been diving rebreathers since it became popular in recreational diving in the mid 90s.

He was trained by the late Mr Rob Palmer, a pioneer of Technical Diving, on the Drager Dolphin Rebreather. Davy is also a TDI KISS Rebreather Instructor, currently owns a rEvo III Hybrid, a Classic KISS mCCR as well as a Halcyon PVR-BASC rebreather. Aside from giving technical diving trainings to avid divers, he is also a long standing Instructors with several training agencies:

  • PADI Master Instructor (PADI # 15973)
  • NAUI Instructor Trainer (Naui # 9020)
  • PSAI Instructor (PSAI # 48)
  • SSI Instructor (SSI # 8030)
  • CMAS Instructor (CMAS # M3 SGP 022)

It all started with his passion in diving, and in 1975, he took up a free diving course, got himself certified as a one-star diver which he had to endure all kinds of tough training. From then on, he just went all his way to pursue his hobby. He had dove to the once famous Anambas Oil Rigs – a depth of 92m, a couple of times with some legendary figures.

Then, in 1997, together with one of his buddy, they went to Florida to do a Cave Diver course at Ginnie Springs. It was through him that the Global Underwater Explorers (“GUE”) course director, Andrew Georgitsis came to Singapore and conducted the first GUE course in Tioman Island, Malaysia.

Davy was one of the earliest diver to dive HMS Repulse and HMS Prince of Wales. He had since 1999 led two groups of British tech divers and a Dutch group to dive the historical wrecks. The dives on these two historical wrecks were documented on Youtube.
