Johan and Ed Betts of ANDI

Johan (pictured here in grey with Ed Betts of ANDI) was one of the first operators in the area and was on the wrecks the day after the Americans left Subic. This makes him one of the most experienced divers in the area having spent more time on the wrecks than anyone else. During the American occupation of Subic Bay, the wrecks were off limits to recreational diving so there are few who have ever had the opportunity to dive this pristine area.

Johan is actively searching for more wrecks and to date, has been able to add new wrecks to his list of dive sites.
