It is common sense to at least appreciate on some level that the environment in which you were trained may be more benign than some others around the world and that you (and your equipment) may not be ready for those conditions. Whether or not further training is required really depends on the quality of the training the diver has received to date and their willingness to seek out an experienced buddy and listen. Trust me if you make the trip up here to the Great Lakes in winter with your warm water regulator and 5mm jumpsuit, a free flow and hypothermia will be waiting for you!
