Why dive with a buddy?

Never dive alone - One of the key scuba diving safety rules. When scuba diving always dive with a buddy no matter where you are. When you do dive with a buddy, keep an eye on him/her to make sure everything is OK (and hopefully they are doing the same). If something happens, that buddy can be the difference between life and death. Never violate this rule. Also do a pre-dive equipment check with your buddy.
