We seem to be going WAY off track on this thread,we should go back and look at the title,the subject seems to invlove those of us who solo dive and why it is such taboo,why is it such a problem if those of us who do feel we are resposible and/or comfortable enohg to do so.We are all aware of the danger and inherint risk, however ,as a working diver and the background and experience of 20 or so years ,I find it not only nessacary from time to time ,but as stated in the thread,it is a mental check to know it is all up to you and your expertise.I do not rebut or condone this practice for everyone,but then again,not everyone can drive a 200mph race car safely either,it is a personal choice as well as a challenge for those of us who do ,and may be a goal for others.For those of us who do ,be safe and enjoy,for thse of you who don't, but may want to,be patient,be sure and most of all,know your limits,your average air consumption,your equipment ,your dive area and anything else that may make you doubt your dive,then........enjoy and be safe!!!!!
