About

Phil joined Manta Dive on Gili Trawangan in 2014 armed with 50 dives, a rescue diver certification and a brand new Suunto D6. He quickly worked his way to instructor and soon after began his journey in tech and switched to a Shearwater Perdix. In 2015 he bought his first CCR and never looked back. Since then he has become full cave CCR certified, done expedition trimix dives to 145m on his SF2 eCCR, dived dual rebreather configurations and become an SF2 instructor trainer. Meanwhile in the open circuit side Phil is an extended range instructor and a TDI instructor trainer for ANDP, DPV and Sidemount. His main passion is exploration of the deep trimix CCR variety and shark videography around the Gili Islands in Indonesia.

Christoff is the instructor named in most of Manta Dive Tech's technical reviews, from sidemount through to mixed-gas rebreather courses on the SF2. The consistent thread is pace: students repeatedly say they were never rushed, that theory sessions ran past the syllabus into whatever tech topic came up, and that anything unclear was re-explained calmly until it landed. A recreational instructor of seven years with eighteen years' diving called his AN/DP "by far the most in depth and enjoyable course I have done", and credited him with fixing sidemount harness problems nobody had previously caught. Divers come back — several describe a progression run entirely with him from sidemount through to rebreather, and one couple returned across a year for DPV, AN/DP, guided tech dives and then a CCR course. Reviews also place him at the Gili tech sites specifically, naming Linda's Reef and the Rainbow Reef wall and what is down there.
