The teacher's explanation of what diving is kinda incorrect. "deeper is better hurr durr" no it is not. In Scuba Diving, there is no "goal" that is always set- each dive has its own goal and objectives. It could be for fun, for research, to see something specific, or anything else. I love the attention they give to the buddy system- it really is crucial for diving. Also, the teacher must have an instructor's license, or else he can't teach. Where's your goddamn license my guy. also,
@DanJADO scuba diving courses usually take a couple of days or so, and one day to prepare for the first exam isn't outlandish. They are probably starting their Open Water Diving course, which is around 5 days long.
