Description:

From the pontoon entry point the bottom drops gradually down to about 28M when certainly the bottom falls away sharply into an 80M abyss. Using the wall as a useful reference we descended into the dark to our limit of 40M. The steady ascent home took us via the BAE146 and Wessex helicopter.

Notes:

Care should be taken not to sink deeper than planned with close monitoring of visual and computer references. NDAC guidelines require an alternate air source such as a pony.
