Dan Tager and I met up at Gilboa last Saturday. It was Dan`s first fresh water dive. He liked feeding the fish, the plane and helecopter. Going down to the tubes was a bit much for him I think. The thermocline in a confined fresh water area can be extreme when compared to the ocean. Temp was 80 on the surface and sropped to around 60 by the tubes. It was still a nice dive. My dive season is almost up, until I get my drysuit.
