We took the dry suit course and then Silfra dive trip. I can't say enough about the experience. Stefanino was an excellent instructor, he was extremely knowledgeable and professional. We felt at ease within minutes of being with him. We were fairly new to diving and he adapted to our skill and showed us a great experience both in the course as well as the Silfra. We highly recommend Dive.IS, they made the experience simple and worry free and if you get the chance recommend Stefanino he is an excellent guide and well versed in his craft. We will definitely be back.
