Hi this is David at Phuket Dive Tours sorry you are finding things confusing - most of our customers find that sending an email or using the online chat facility a much easier way of communicating with us however thanks for the message in relation to one certified diver and one non-certified diver scuba-diving at Racha Yai in March 2019.
Typically all scuba-diving activities for beginners start at around 4,000 THB for two dives as a certified diver you would be expected to pay 3,500THB this would include equipment for each of you. Please note that additional transfer charges may apply depending on your hotel location
If your friend is a beginner he will need to read the medical form as a beginner if you answered yes to any question he then needs to see a doctor to get written permission scuba-diving the medical form is listed on our website under scuba-diving for beginners.
If you email me with your personal details as well as your hotel location we can then give you a price for scuba-diving based on your hotel location. Our email address can be found on our website.
