Diving in spring tides at work a couple of days ago , i was diving on moorings putting marker floats on the anchors , i was lugging that much gear (tools etc.) i ran out of places to connect things so i thought id tie the marker float rope to my weight belt , the second i entered the water i realized what i had done , my weight belt and knife plumetting in to the abyss and me flopping around on the surface , i had clipped my belt buckle over the float rope. what a clown !
