I'm really shocked at the review of Sea Tel Aviv by The couple who wasn't happy. My son and his friends have done dives with Greg on at least three separate occasions and each time they enjoyed it more than the last one. One of the guys on the first dive was a bit fearful, but Greg's patience, understanding and perseverance enabled him to go for it and continue on to do further dives. I can't say enough for this diving lug. It's a winner.
