Thanks for the quick reply I received but I hope that we respond to each other in a proper manner , since no qestion is stupid. I have stated in the beginning of my letter that I am new in this field. I am perpating a study about diving so I thought that asking professionals will be of help but in a good manner. To continue my so called stupid question what is the difference between diving and scuba diving. Is taking the breathing appratus is scuba while free diving is not scuba
Thanks
Thanks
