You will find all prices for dive courses on the dive courses page. Fun dive is $30 without equipment or $50 with full equipment for one dive. But the price can change depending of the area, i try to keep the same price or a bite lower than itch area.
You can also rent a dive computer or a torch for $10 a day and underwater camera Canon G15 or G16 for $30 a day.
For a sailing trip the price is $100 for a day, including private cabin, meals, non-alcoholic drinks, my home made Ginger beer, snorkling and beach trip. Alcohol is available on board. After discussing your requirements i can personalize your trip and give you a final price.
