Have just completed a whirlwind tour of my divecentres in Vietnam: Rainbow Divers : Saigon: Busy teaching resident expats theory + poolwork for PADI Courses. Nha Trang: Diving in the Hon Mun Marine Park. Viz 15m but a bit chilly (23c). Loads of Nudis; they seem to like the colder water! Team gearing up for next IDC. Whale Island: Peaceful 'desert Island' location. One of the very few places in Vietnam where you can enjoy quality beach diving. Con Dao: Stunning location in the middle of nowhere! Totally unspoilt. Viz around 10m and 27c temp. Loads of Turtles!
