Cox is the technical instructor at Dive Dojo in Sabang, Puerto Galera, where he is also the boat captain. A ScubaBoard course report covers Advanced Nitrox, Decompression Procedures and Extended Range taken with him at Sabang and calls him a great instructor; he is also named twice in threads asking where to train technically in Puerto Galera. Those threads are old enough to place him at Capt'n Gregg's, where he taught before Dive Dojo. Recent student accounts are scarce, so ask for references.
