Born in London in 1964. Dave is a Geologist by education. He learned to dive whilst living and working out of Hong Kong, and turned professional, as a Divemaster in 1991 and then a PADI Instructor in 1992. When IANTD came to the Philippines in '95 he was among the first group of Instructors certified, and currently holds the ratings of IANTD Trimix Instructor, plus Normoxic Trimix and Gas Blending Instructor Trainer. A lot of Dave’s current effort is in the area of dive trip organization and trying to find new and interesting opportunities for our divers to enjoy.

Sam Collett - IANTD Trimix and Technical Wreck Instructor Trainer

Another Brit, originally from Brighton, Sam began diving at Asia Divers in 1994. He was at that time living in Sydney and owned a very successful Stone Masonry and Restoration business, which he ultimately sold and moved to full time diving as a career. Sam is an IANTD Instructor Trainer to the levels of full Trimix, Technical Wreck and Gas Blending, and also teaches DPV, Essentials courses, Rebreather, and all of the PADI/DSAT levels to Tec Trimix. Sam's instructional and supervisory skill, patience, and attention to individuals divers particular needs and abilities have made him a tremendously popular and highly respected member of the Tech Asia team, and in the field of Asian technical diving generally. Sam also involves himself actively in dive travel, having put together excursions all over the Philippines, and from Micronesia, South China Sea, Java Sea, Sri Lanka and to the Burma Banks.

Ferg Peoples - - IANTD Trimix and Technical Wreck Instructor

Ferg, who comes from Ireland, got upset with the weather one day and decided the tropics were worth investigating. He began diving in 2000 and quickly realised that sand and sun can even beat a good pint of Guiness. Arriving in the Philippines in 2005, the passion he developed for Technical Diving sabotaged his savings and back to Europe it was for the poor fellow. An email about a tech liveaboard in the South China Sea lured him back in ‘08 and he hasn’t left the diving business since. Now an IANTD Trimix , Technical Wreck Instructor with GUE training to Tech 2 level, and through IANTD on KISS Rebreathers. He enthusiastically and capably jumps in to deal with anything and everything that needs doing. He intends to be a part of the Philippine Tech Diving community for a long time to come.
