In the middle of our trip a large white, about 18′ came straight at me, it was viewed by the people in the boat, not me. They warned me about the shark, I thought it was farther away from me than it was so I continued diving. They eventually said the shark had left the area, I had great confidence in my safety because I knew my shield was on and working and that there has never been an attack on a person with a Shark Shield. Later I found out that the shark came within 3 meters of me and the shield and then made a left turn to avoid the shield. Just wanted to say thanks.
