East Coast Diving my good man, he lives in Long Sutton, just over the Lincs border, but he is often diving round your way, Winterton etc. He will collect and deliver, ie pick up on a return and deliver on a way out, cost is £25 for a hydro and £10 for a visual, may just be a little more to allow for fuelling the Landie, contact details...
