MarkA...No, that wasnt bottom bottom.... 52 was at 47 feet! Sorry for the confusion. Im not cert. to deep dive yet. Working on my advacned but ran out of dive time with Padi instructor last year. I will have to do my deep dive for the cert there at Gilboa this summer. But even once certified, dont think Ill do any deep dives there... I hear its just cold and dark! Are you doing the Record attempt there this July??? I signed up and mailed in my money last week and I plan on camping with a few friends, so let me know if your going, we can at least meet up there if not sooner for some dives! Julie
