Lead

Realised today I hadn't blipped anything with this weeks challenge in mind so here's my shot at it!
As SCUBA divers Nigel and I use lead weights to get under the water so this is a selection of the different shapes and size they come in. In addition when we climb back aboard a RIB at the end of a dive the first item we take off and hand in is the weight belt , so in this instance it 'leads' the process :)
