An awesome, albeit cold, Dive Against Debris with a great turnout on a beautiful sunny day. A mix of diver levels and ages but all very keen to do their bit and brave the 8 degree water, some only in wetsuits! With a shallow, silty bottom around some private moorings and slipways we weren't sure what we might bring up from the 'depths'. I am sure there was more down there but it's hard to say with visibility between 0.2 and 0.5 of a meter. The relatively small amount we did find is a good sign of the 'tidy kiwi' attitude in and around the water but it's also good to remove what we did find and thanks to all the helped. After a sausage and cup of tea we documented what we had, got some photos and chucked our haul into the skip before heading back to the shop or home to clean gear and enjoy the rest of Sunday, feeling like we had done a good deed! Thanks to all involved!
