Okay, it seems like we are comparing apples and oranges here. Fire rescue teams work under the "we can save a life and rescue them" mentality like they do when responding to fires, and we love them for that. In reality, most dives are salvage jobs with no urgency and all the pre-requisites for a detailed crime scene approach. So lets not beat each other up here, because one day, your Fire Diver may be your rescuer and vice versa.... Whoo Yaa, Deep sea !
