Kitesurfing is a sport I do on occasion the same as surfing. If I am in a good location , Sri Lanka for example. Yes, I have professional qualifications for scuba diving and am presently working on some more. Not sure if I want to be an instructor though, just Dive Master and adding other additional technical skills such as Nitrox. Vietnam and Ho Lang Bay is well worth a visit, you are spoilt for choice in SE Asia actually.
