We have done many Marco Island jet ski dolphin tours over the years, including several with Avi and several with other guides. He is definitely the best! He is fun, informative, and knows his way around the 10,000 Islands, but most of all he always finds dolphins and gets them to interact with the group. Don't be mislead by the small number of reviews, he has been doing this for years and just recently went out on his own. If you are looking for a jet ski tour, this is the one you want.
