I was thinking I could always rent a jacket style if needed while I'm actually doing my course it just doesn't make sense to me to change my equipment while training to make situations easier because if a situation arises where I need to use my training in a state of emergency and I am using different gear I won't be as used to the situation where as if I train in what I intend to dive in in the future this will all be more familiar and practiced but I understand a there will be a strict chain of command and I am at the bottom "there's not to reason why there is but to do and die"
