ok ill say it lock the gate to that hole it is not worth it .that was my recomendation after the search was completed. There is no need to allow anyone else to push a search back in that cave system . bens equipment and training screams stupid and I am not willing to risk the death of a real caver or wantabe to ease the suffering of a father who has been offered all the sympathy of this industry and the efforts of many great people at no cost to him and accepted the help but refuses the facts presented to him. He values the body ( death certificate)of his son over the life of a diver tell him to go get the training spend a few years gaining experience and go diving. if he wants to spend money to make himself feel better pay the divers that already searched and risked there lives and families( at no cost to bens family) as well. I dont want to come off as uncaring but there comes a time to move on and we have reached it. IF you allowed edd and others to go into that enviroment and then reject their findings despite the years of training knowledge and experience brought to the table. then you are in a grief,greed or emotional funk that you need professional help with. sorry for the harsh tone but a divers life is worth a lot to me.
